Abstract

Bacterial blight of rice caused by Xanthomonas oryzae pv. oryzae is one of the most destructive diseases of rice. Development of resistant varieties is the most economical and environmentally friendly strategy for the management of the disease. Phenotypic screening of 50 rice germplasm accessions from South India were carried out by artificial inoculation using three virulent isolates of bacterial blight pathogen. Two accessions were moderately resistant against two Xoo isolates, (Xoo13 and Xoo63). None of the accessions tested were resistant or moderately resistant to the most virulent isolate Xoo57. Out of the 50 accessions six were moderately resistant to Xoo 63 and two accessions were moderately resistant to Xoo13. All other accessions were moderately susceptible to highly susceptible in nature. The genotypic survey was carried out using molecular markers linked to Xa4, xa5 and xa13 and Xa21 genes viz., MP, RM 122 xa13 prom and pTA 248. No amplicons specific to xa13 and xa21 allele were detected showing the absence of these two genes in the germplasm screened. 25 accessions amplified 150 bp size fragments specific to Xa4 gene. 20 accessions amplified 240 bp fragments specific to xa5 gene. 10 accessions carry Xa4 and xa5 genes in homozygous condition. Among the two accessions phenotypically moderately resistant to two isolates of the pathogen, one contains only xa5 gene and other does not carry any of these four genes studied. Further search for other genes contributing resistance is needed. The accessions having moderate resistance carrying Xa4 and xa5 genes could be utilized for the development of bacterial blight resistant varieties through molecular breeding.

Abstract

Bacteria are one of the major factors causing haemorrhagic septicemia to the edible fishes and create a growing threat to aquaculture. Thus, necessity of use of chemical compounds with antibacterial activities has increased to protect the fishes against the bacteria. Nowadays, use of commercial antibiotics is no longer effective in aquaculture, due to increased incidence of appearance of antibiotic resistant strains. The uses of medicinal plants as therapeutics have no side effects or very less side effects than the antibacterial drugs. In the present study antibacterial activity of Piper betel (Paan) and Syzigium aromaticum (Labanga) were tested against Pseudomonas aeruginosa strain PKB113 (accession number JX426137 in the GenBank database) which was isolated from the septicemic lesions of the freshwater edible fishes. The in vitro antibacterial activity test of both the plants was done by means of disc diffusion method as well as bacterial growth curve analysis. The present study also showed that methanolic extracts of both Piper betel (Paan) and Syzigium aromaticum (Labanga) have significant antibacterial effect against the test bacterium Pseudomonas PKB 113 but Syzigium aromaticum (Labanga) was more effective than Piper betel (Paan). From the present study, it can also be commented that the use of medical herbs may be an alternative treatment for the remedy of disease as to replace antibiotics, which is preferable for health of animals and humans’ beings. It is also an option to reduce cost of treatment, and to promote the use of available natural sources within the country.

Abstract

The current study deals with the antimicrobial activity of various fractions of different extracts from Anisomeles malabarica and was analyzed by using the agar well diffusion method. To determine the zone of inhibition in bacterial and fungal organisms using plant extracts of aqueous and benzene solvents. The concentration of extracts in (standard, 25, 50, 75, 100μg/ml) was tested against bacteria such as Streptococcus pyogenes, E. coli, Salmonella sp and Klebsiella pneumoniae. For antibacterial activity, the zone of inhibition (mm) of extracts was compared to standards such as streptomycin. The extracts of Anisomeles malabarica were tested against fungi such as Aspergillus niger, A. flavus, A. terreus and A. fumigatus as well as standards like fluconozole for antifungal activity. The maximum zones of inhibition for leaves, flowers and seeds were aqueous in bacteria and benzene in fungi. When all parts of Anisomeles malabarica were compared, the maximum concentration was 100 µg/ml. The results support the use of A. malabarica to treat a variety of infectious illnesses. Finally, these results suggest that Anisomeles malabarica can be used as a source of antibiotic compounds for potential bacterial infection treatment and medication development. Recent research has identified the most valuable Anisomeles species for phyto-pharmaceuticals.

Abstract

Biological control consists of the introduction of beneficial predatory (or) parasitic species into the cultivation system. Integrated pest management (1PM) is an alternative to unilateral intervention strategies using agrochemicals with a wider focus on the ecology of the insect pests as well as the crop plants. Metarhizium anisopliae is the most utilised fungal species and the natural genetic variability of entomopathogenic fungi is considered one of the principle advantages of microbial insect control. Metarhizium anisopliae, an anamorphic fungus related to the phylum Ascomycota is the most intensively studied genus of Metarhizium, considering that the teleomorph is Cordyceps brittlebank isoides. The reproductive structure of Metarhizium anisopliae (the anamorph, the most commonly encountered form) consists of conidiophores and conidic Metarhizium anisopliae produces leveduri-form structures (or) blastospores and appressoria via mycelia differentiation. Blastospores can function in certain cases as reproductive units and are produced in submerged cultures. Entomopathogenic fungi are unique in that they can produce a wide range of bioactive compounds, including helvolic acid (1,2-dihydrohelvolic acid), each with its own molecular formula and molecular weight. Metarhizium anisopliae was discovered to be insect material dependent and to produce antibacterial compounds, which were purified from culture to homogeneity. This specific novel bioactive compound indicated that insect-derived material would be useful for enhancing the diversity of compounds produced by entomopathogenic fungi.

Abstract

The present work is an update on earthworm fauna of Eastern Haryana forming main part of Trans-Gangetic region. Survey of earthworm species in this Eastern Haryana with reference to diversity, distribution, and composting efficiency of local species revealed the presence of 14 species of earthworms belonging to 5 families, 11 genera. Out of 14 species Two species belonging to family Ocnerodrillidae (Gordiodrilus elegans) and Lumbricidae (Eisenia andrei) was reported for the first time from Trans-Gangetic region of Haryana. During the survey Lampito mauritii was the dominant species in this surveyed region representing 54.81% of total earthworm population. This anecic species had been recorded almost from all studied pedoecosystems. Therefore, the potential efficiency of this species of earthworms (L. mauritii) has been done by culturing them in kitchen waste rich organic matter. It was found that L. mauritii can be used as a vermicompost species in the northern region of India. Along with this the genetic diversity of some species had also been studied and phylogenetic relatedness among different species of earthworms was constructed which showed the presence of highly diverged lineages species of earthworms inhabiting Haryana soils. For genetic studies 10 random primers (OPA-1, OPA-2, OPA-3, OPA-4, OPA-5, OPA-6, OPA-7, OPA-8, OPA-9and OPA-10) were used in the amplification of DNA from the six species of earthworms (Eisenia fetida, Metaphire posthuma, Eutypheous incommodus, Lampito mauritii, Perionyx simlaensis and Dichogaster bolaui). Based on amplified primers it is concluded that OPA-6 primer, revealed slight differences in Eisenia fetida from other species like P. simlaensis and D. bolaui. Primer OPA-8 revealed a monomorphic pattern of bands starting from 250bp to 750bp in five species (E. fetida, M. posthuman, E. incommodus, L. mauritti, P. simalaensis).

Abstract

Vermicomposting is a green technique used to produce organic compost from organic waste with the aid of specific earthworm species. The resulting compost is rich in nutrients that can improve plant health and fertility. This study was conducted to produce organic compost using a developed vermicomposting technique and to enhance the exchangeable nutritional content in the soil for utilization in sustainable agriculture. The experiment was carried out with Eisenia fetida worms in a treatment technique using fish waste, mango pulp and biofertilizer. Six feeding compositions – different combination of fish waste (FW) + Mango pulp (MP) waste (C1, C2 and C3) alone; C1/C2/C3 + Earthworms (E. fetida) EW (C1E1/ C2E1/ C3E1); C1/C2/C3 + EW + Azospirillum- AZ (C1E2/ C2E2/ C3E2); C1/C2/C3 + EW+ Phosphobacteria - Pb (C1E3/ C2E3/ C3E3); C1/C2/C3 + EW+ Rhizobium-Rb (C1E4/ C2E4/ C3E4); C1/C2/C3 + EW + AZ+Pb+Rb (C1E5/ C2E5/ C3E5). The physiochemical parameters, namely pH, electrical conductivity and seven different nutrients, were assessed in different compost samples and the growth and reproductive performance of epigeic earthworm Eisenia fetida in biofertilizers enriched FW + MP vermicomposting was studied. The vermicomposting co-efficient of physicochemical parameters shows an increased trend in EC, OC, N, P, K, S, Zn and Fe, except pH. Maximum number of earthworms was recorded in C1E3 and the highest average body weight and body length were observed in C3E5. The microbial populations and availability of food materials from biofertilizers enriched fish waste with fruit waste increases the biomass, average body weight, average body length and also increases the reproductive.

Abstract

Basal kernel blight disease of barley due to Pseudomonas syringae pv. syringae (Pss) is known for remarkable crop losses worldwide. Current investigation was carried out for assessment of physiological and biochemical changes induced due to natural infection of Pss in barley seed samples. It was observed that moisture, fibre, ash and total carbohydrates were variable with significant values in all infected samples. Total phenols increased significantly in all Pss infected seed samples. Notably protein content was increased significantly in the infected samples, whereas crude fat, crude fibre and total carbohydrates decreased significantly. However, the enzymes such as polyphenoloxidase (PPO), catalase (CAT) and peroxidase (POD) were remarkably higher in the infected samples. The results suggest that interaction of Pss with host metabolism interferes with biochemical pathways and production of various defensive enzymes and other products in process to bring disease symptoms on the barley. It is concluded that this study will serve as a pool of information to understand the response of barley to Pss infection on biochemical basis.

Abstract

The most common sterilising silver nanoparticles used in consumer and medical products include fabrics, food storage bags, refrigerator surfaces and personal care products. This study exhibits the synthesis of silver nanoparticles using Pleurotus ostreatus. The biosynthesized Ag-NPs were characterized using a UV-Vis spectrophotometer, Fourier transform infrared spectroscopy (FTIR), Scanning electron microscope (SEM), Transmission electron microscope (TEM), X-ray diffractometer (XRD) and antibacterial activity. The maximum absorption peak was measured in the UV-Vis spectra of silver nanoparticles at 460 nm. The next analysis is performed with a comparison of control and concentration 10mM. The FTIR were detected by the presence of functional groups necessary for the conversion of silver nitrate to silver ions. The formation of silver nanoparticles was observed by SEM analysis of the brown colour stable samples, while silver nitrate-treated samples revealed well-dispersed nanoparticles. The TEM images revealed that the size of Ag-NPs was found to be about 50 and 100 nm. Ag-NPs, XRD pattern showed 2θ values, which are related to the silver (111) crystalline phase index. Aeromonas hydrophila, Bacillus cereus, B. subtilis, Escherichia coli, Klebsiella pneumoniae, Vibrio cholera and Staphylococcus aureus were the microbes selected for the current study for the antibacterial activity of the silver nanoparticles was performed by well diffusion method. The maximum zone of inhibition was found in the control (10.16±0.18mm) at Klebsiella pneumoniae and concentration 10mM (12.20±0.08mm) at Bacillus cereus and least against the control (7.30±0.22mm) at E. coli and concentration 10mM (7.67±0.72mm) at Klebsiella pneumoniae. This study concluded that the silver nanoparticles have a significant amount of potential as an antimicrobial compound against the pathogenic microorganisms studied and can be used to treat infectious diseases caused by bacteria. Silver nanoparticles have a major role on nanotechnology and nanomedicine.

Abstract

Pollination can increase the yield, quality and stability of fruit and seed crops. Animal pollination plays an important role in sexual reproduction and the successful pollination of many crops. Inadequate pollination not only reduces yield, but can also affect yield and produce a high percentage of poor-quality fruit. Most of our crops are poorly adapted to biotic and abiotic stresses such as disease, pests, drought, salinity and the constant introduction of new adaptive genes lead to preserve crop diversity and enhance pollination. Pesticides kill pollinators directly, and herbicides kill pollinators indirectly by reducing what they eat. Habitat destruction has reduced pollination in agricultural and natural areas. Pollinator numbers are believed to be declining worldwide, resulting in reduced yields in some crops, ultimately impact on food production and food security.

Abstract

The neuropeptide S receptor is a member of the G-protein coupled receptor superfamily of integral membrane proteins which binds neuropeptide S. It was formerly an orphan receptor, GPR154, until the discovery of neuropeptide S as the endogenous ligand. In this In-silico work, we found out the total number of mutated amino acids of the NPSR1 protein present in the domain’s regions. The normal and mutated structure of the NPSR1 protein sequence was modelled using automated molecular modelling techniques. The modelled structure was validated and the 3D structure was visualized using advanced molecular visualization tool in order to view the molecular structural details with its mutated amino acids domains region in 3D form. The overall results clearly deliver the involvement of the mutated amino acids in the domains region of the modelled NPSR1 protein. Finally, we conclude that the identified domain regions of the amino acids act as potential drug binding sites which will be beneficial further in the field of drug designing for NPSR1 related diseases.

Abstract

The present study mainly focused to analyze the behavior of Soybean prices in Bidar and Dharwad markets in Karnataka and forecasting the prices for the future. Based on secondary data from January 2005 to October 2022, the future prices were predicted for the next six months, by employing the Auto Regressive Integrated Moving Average (ARIMA) technique. The annual increase in price trend of Soybean in Bidar and Dharwad markets were observed to be Rs 288.0 and 388.0 per quintal per annum. The highest seasonal indices of prices were observed in the month of February (106.1), May (109.3) in Bidar and Dharwad markets respectively. Highest indices of arrivals were found in November (381.0) in Bidar, (175.5) in Dharwad market. Maximum R-Square (0.92), (0.91), minimum Mean Absolute Percentage Error (MAPE) (8.563), (9.902), Root Mean Square Error (RMSE) (290.65), (313.59), Mean Absolute Error (MAE) (196.21), (209.24) and Normalized BIC (11.45) and (11.550) respectively in Bidar and Dharwad markets, were used as a criteria to select the best model for price forecasting. Based on the above criteria the model (1,1,2) (0,0,0) and (0,1,2) (1,0,1) were found to fit the time series to predict future prices. The forecasted price of soybean would be ranging from Rs 4678 to 6301 and Rs 5028 to 6535 per quintal during the cram months in Bidar and Dharwad markets respectively.

Abstract

New eco-friendly techniques should be used to fulfill the demand for foodstuffs of the day-by-day increasing population. So that we can overcome negative impacts on the environment as well as on land because of the overuse of chemical fertilizers and pesticides for enhancing crop productivity and increasing yield. It leads to hyperaccumulation of chemicals, soil degradation, soil compaction reduction, reduction in soil organic matter, leaching problems, and soil becoming infertile. In addition to this climatic change is one of the major problems. To overcome this PGPR growth-promoting bacteria can use direct and indirect mechanisms which lead to the acquisition of resources and also helps in the regulation of plant hormone levels and also assist in suppressing the inhibitory effects of pathogens on plant growth and development. It also acts as a biocontrol agent (BCA) to soil-borne pathogens and ISR. This can be achieved by the ability of PGPR to synthesize compounds such as Siderophore production, and the synthesis of lytic enzymes which hydrolyze the phytopathogen’s cell wall and suppress negative effects on crops, Antibiotic production is one of the important antagonist’s mechanisms against plant pathogens and also acts ISR to certain pathways for inducing systemic resistance and stress detecting markers which includes ACC deaminase and it produces various stress markers enzymes. Indirect mechanisms also cope with some nanobiotechnological aspects to improve crop productivity by creating certain genetic manipulation, thus suppressing detrimental effects on crop productivity.

Abstract

The present study revealed complete information on length-weight relationships (LWRs), length-length relationships (LLRs), and meristic counts (covering different fin rays and ocellies) of a total number of 150 Macrognathus aral species collected from lotic water bodies and fish markets. The total length of the male and female species results from a range of 18.3cm to 32.5cm and 15.7cm to 29.0cm while body weight varies from 21.35gm to 156.6gm and 29.9gm to 138.9gm, respectively. The parabolic equation between total length and the total weight of M. aral is as W = 0.177000982 L2.4837 for male species and W= 0.105737 L2.9929 for female species. A strong relationship between length and weight shows a 93% (P<0.05) correlation in females and 82% (P<0.05) correlation in males. The values of ‘b’ showed negative allometric growth (b<3.0) in both sexes. The mean values of Fulton’s condition factors (K3) shown in male and female species were 0.378 and 0.558 respectively, while on the other side the values of Modified condition factors (Kb) shown in male and female species were 1.875 and 0.571, respectively, which indicates good health condition of the species in their natural habitats.

Abstract

Crop failure due to natural hazard and other human interventions can cause a serious matter of concern to a rural population dominated agricultural country like India. The issue of food security and nourishment pose a major stress to the economy and sustainability of agriculture in the near future. Agricultural risk can be categorized as production risk, price or market, financial or credit, and institutional risks etc. The farmers are not assured of good quality and disease-free crop which is essential for obtaining reasonable yield sufficient to recover expenses. Crop insurance is one of the major management strategies to overcome risk to greater extent. The present study is focused on assessing the parameters of risk and identifying the risk prone zones and stressing the need for crop insurance as a measure of mitigation in districts of Rajasthan.

Abstract

Lycopene is a lipid soluble carotenoid compound synthesized naturally by plants and microorganisms. It is one of the dominant antioxidants among dietary carotenoids and is principally responsible for imparting red colour in fruits and vegetables. Emerging research suggests, lycopene as an important micronutrient with many health benefits and it is a potent anticancer agent against several types of cancers including prostrate, epithelial, oral, hepatocarcinoma etc. Fruits of Elaeagnus species are an abundant source of lycopene and its derivatives. However, this genus remains underutilized due to lack of proper knowledge and scientific study. Here, in this review we have summarized the chemical nature of lycopene, its availability in different species of the genus Elaeagnus and its role in prevention of cancer. The obtainable data is promising, however more detailed information on the bioavailability, biochemistry and anticancerous activity of lycopene are needed to utilize fruits of this genus as functional food and in pharmacological industries in near future. We hope that this review will prompt future researches and shade light on the value of lycopene in the fruits of the genus Elaeagnus.

Abstract

Similipal is one of the Sal dominated large forest in Odisha and also in India. There are many forest types are present in this Biosphere Reserve such as- Tropical dry deciduous forest, Moist Deciduous Forest, Semi-evergreen forest, Mixed deciduous forest, High Level Sal Forest, Hill Forest, Savannah and Grassland meadow types. That’s why in this paper we analysis all the tree species found in this Biosphere along with their ethno-medicinal importance. The main objectives of the study are to identify and classify all tree plants present within the reserve and documented their ethno-medicinal uses. The study was done in three seasonal conditions- pre monsoon, post monsoon and in winter. Many photographs were taken for their further identification. Plants were collected in field and note their habit, habitat, flower colour, fruit colour, odour, and after that prepare herbarium, analyzed through proper and available flora. In present study we exclude tree species of Monocotyledons, Gymnosperms and Pteridophytes. The present study deals with only tree species present in Similipal Biosphere Reserve. More attention should be paid to the tree species showing very low amount. Similipal Biosphere Reserve is a protected forest, still the forest vegetation is experiencing destruction due to the interaction of the local people for their dependence on the forest for the timber, medicine, fire wood, as well as non- wood forest products. Overgrazing by the livestock has added to the parameter of destruction of newly germinating seeds. This preliminary study will add to the knowledge about the present status of vegetation in the biosphere. Many endangered, rare and endemic species are also at high-risk position. Plantation of the species and thereby restoration of the forest vegetation is the key massage of the survey.

Abstract

The interspecific association of egg parasitism between membracids and chalcidoid parasitoids was studied. Gonatocerus brevifuniculata and Gonatocerus narayani (Mymaridae), Mirufens afrangiata and Brachygrammatella indica (Trichogrammatidae), Centrodora azizi and Centrodora mumtazi (Aphelinidae) parasitized the eggs of membracids, viz., Leptocentrus taurus, Otinotus oneratus and Oxyrhachis taranda. The parasitisation by each parasitoid species was calculated. The emergence hole formed by each parasitoid species was specific on the host eggs parasitized by each chalcidoid species, from which percentage of parasitisation was calculated. The respective percentage of egg parasitism in Leptocentrus taurus by Gonatocerus brevifuniculata, Brachygrammatella indica, Mirufens afrangiata and Centrodora azizi was 6.80, 2.49, 5.77 and 3.19; in Otinotus oneratus by Gonatocerus brevifuniculata, Gonatocerus narayani, Brachygrammatella indica, Mirufens afrangiata and Centrodora mumtazi, was 9.90, 11.80, 7.15, 6.99 and 10.36; and in Oxyrhachis taranda by Gonatocerus brevifuniculata, Gonatocerus narayani, Mirufens afrangiata and Centrodora azizi was 7.47, 6.68, 4.18 and 3.80.

Abstract

Oviposition studies using ovitraps are proven advantages in vector surveillance, because they are used to monitor mosquito species as well as pre and post density counts, and has been used to identify areas with high concentrations of vector breeding based on egg density index from unexposed breeding sites and surrounding areas. In the present study, the ovipositional preference of Aedes albopictus in different containers (ovitraps), viz., new coconut shell (C1), used coconut shell (C2), new black coloured plastic cup (C3), and used black coloured plastic cup (C4) was assessed in three different types of experiment sets viz., (i) in the above mentioned containers (E1), (ii) rubber leaf infusion placed inside the containers (E2), and (iii) rubber leaf infusion + Bacillus thuringiensis placed inside the containers (E3). Further, different treatments ranging from T1 to T8 were set up with varied concentrations of rubber leaf infusions with presence and absence of Bacillus thuringiensis was also experimented. The results revealed that maximum eggs were oviposited in C4, and amongst the experimental set up, maximum number of eggs were oviposited in E2. Further, T4 (Container holding rain water + 10% rubber leaf infusion with Bacillus thuringiensis) recorded the maximum number of eggs oviposited. The present study demonstrated that the black-coloured containers and the rubber leaf infusions attracted Aedes albopictus and stimulated its ovipositional preference.

Abstract

Shrimp production in India has continued to face an increasing challenge in the last two years owing to improper farm and disease management and lack of efficient probiotic availability. India mainly comprises two varieties of shrimp: Pacific white leg shrimp (Litopenaeus vannamei) and Indian black tiger shrimp (Penaeus monodon). Generally, shrimps lack an adaptive immune system to combat invading pathogens. Probiotics have been suggested as a substitute strategy to improve immune function and prevent or minimize shrimp disease. A variety of imported single- or multi-strain probiotic formulations and products have been available in markets, but the cell viability and shelf life of the strains in shrimp farms are questionable to date. The current perspective is that new dietary multistrain probiotics must be formulated and immobilized on fruit-based solid matrices for long-term viability and increased shelf life in India. Dried banana peel powder is suggested herein as a food matrix or probiotic carrier because it is a low-cost fruit waste that is readily available and contains more total dietary fiber with antioxidant activity. Hence, dietary multi-strain probiotics could be ideally viable in the pond environment by reducing the bacterial and organic loads, which will fetch larger profits with additional savings in the production costs of shrimp farming.

Abstract

Seaweeds are exploited for their rich source of pharmacologically bioactive secondary metabolites and phytocompounds for anticancer properties. In the present study, the chloroform extract of Sargassum wightii was tested for antitumor activity against human liver, colon and breast cancer cells. MTT assay was adopted, and the percentage of cell viability was calculated. The inhibitory activity of Sargassum wightii chloroform extract tested at five different concentrations of treatments (25, 50, 100, 250 and 500µg/mL) with control against three different cancer cells showed significant inhibition at higher concentrations. The dose-dependent chloroform extract of Sargassum wightii inhibited cell growth inhibitions in vitro 85% of liver cancer cells (hepG2), 70% of colon cancer cells (HT-29), and 55% of breast cancer cells (MCF7) when compared with control. Cell morphology studies undertaken exhibited the presence of dead cancer cells of liver, colon and breast at the highest concentration (500µg/mL). Detailed examination are needed on the mechanisms involved in cell death, as Sargassum wightii chloroform extract was found to exhibit promising results towards anticancer property.

Abstract

Utilization of indigenous isolates of Purpureocillium lilacinum (Thom.) has good potential for the management of plant parasitic nematodes. Nematotoxic compounds from culture filtrates of P. lilacinum have negative effect on these nematodes. This study was designed to assess the effect of culture filtrates of two indigenous endophytic entomopathogenic isolates of P. lilacinum viz., EEF 4 and EEF 64 on juveniles of root knot nematode, Meloidogyne incognita. The tested fungal isolates as filtrate affected the survival of second stage juveniles at different degrees according to fungal filtrate dilution and exposure period under in vitro study. After 24 hours, significantly higher mortality of juveniles was recorded in the isolate EEF 64 (86.11%), followed by EEF 4 (75.00%) at 100% concentration. Maximum cumulative mean mortality of 72.37 per cent was observed in EEF 64 at 100% concentration, followed by EEF 4 at 100% concentration (63.92%). It can be concluded that these isolates proved to be effective against root knot nematode. Further studies are needed to explore the endophytic nature of these fungal entomopathogenic isolates against nematodes and insect pests.

Abstract

Khurja is a prominent industrial and commercial town in Bulandshahr district, Uttar Pradesh the two main employment and livelihood sources in Khurja are pottery and agriculture, at roughly 50% each. The pottery industry directly employs about 25,000 workers with a further 5000-7000 employed in various support services and allied activities. Other sources of employment in Khurja include trade and commerce and a very small amount of other manufacturing. Tin oxide, also known as stannic oxide, is the inorganic compound with the formula SnO2. The mineral form of SnO2 is called cassiterite, and this is the main ore of tin. With many other names, this oxide of tin is an important material in tin chemistry. It is a colourless, diamagnetic, amphoteric solid. Tin oxide has long been used as an opacifier and as a white colorant in ceramic glazes. Keeping these points in view, the present study is undertaken to assess impact of pottery industry chemical tin oxide on total erythrocyte count, and hemoglobin concentration of Channa punctatus (Bloch.). The TEC and Hb. Conc. have been found to be decreased after treatment due to hematotoxic effect of tin oxide and adverse effect on hemopoietic system of fish.

Abstract

In this work, we have used sawdust, a waste biomaterial of wood working operations for the isolation of lignin in ionic liquids, without using any catalyst followed by production of vanillin from oxidative depolymerization of lignin in the ionic liquid media using oxygen. Out of the three ionic liquids used in our work, the highest lignin and vanillin yields were obtained for [OMIM][OH], followed by [BMIM][OH]. Both the lignin solubility and vanillin production were favoured by high temperature conditions and longer reaction time in [OMIM][OH]. The amount of isolated lignin was improved with the increase in concentration of the ionic liquid. However, the amount of [OMIM][OH] did not seem to affect the amount of vanillin produced. UV-Vis., FT-IR, mass spectroscopy, 1H-NMR and 13C-NMR spectroscopy were used to characterize the vanillin produced by our method. The antioxidant activity of the produced vanillin was evaluated by FRAP Assay and found that antioxidant activity of the produced vanillin is analogous to that of standard pure vanillin.

Abstract

Lipaphys erysimi Kalt is the most damaging pest of the mustard crop, as it affects the crop in diverse ways resulting in reducing the crop yield. In this study, invasive weeds like Parthenium hysterophorus L. and Argemone mexicana L. were used to check their insecticidal effectiveness against mustard aphid using leaf dip and film smear method in laboratory conditions. The bio-efficacy of aqueous extract of both the weeds was compared with efficiency of chemical pesticide Rogor (Dimethoate). The results revealed that, rogor showed the maximum mortality but P. hysterophorus L. showed highest efficiency than A. mexicana L. in both the bio-assays. The leaf dip method was more efficient than film smear method. The present study suggests that chemical pesticides can be replaced with bio formulations derived from these invasive weeds grown in the crop field, which indirectly can be the ecofriendly management of the invasive weeds.

Abstract

The terrific coronavirus disease first started as a locally circulating infection in 2019. The WHO characterized COVID-19 virus disease as a pandemic on 11th March, 2020. This pandemic specified as the greatest global humanitarian challenge the world had faced since the World War II. The COVID- 19 pandemic induced a total 68 days nationwide and different state wise continuous specific lockdowns in India, has a huge economic shock. It stalled the economy with complete closure imposed on enterprises across all sectors in all over the world. That overall unfavourable condition also triggered a massive reverse migration from the urban to rural areas in large parts of the country. Though in initial lockdown phases the agriculture activities were exempted, but the fisheries value chain faced large-scale disruptions. The Govt. and other organizations have taken different mitigation measures to push the sector in the previous sustainable position. Although there were huge negative impacts but the pandemic & it’s regarding lockdowns seem to have numbers of positive impact on the fisheries sectors.

Abstract

Peanut oil is one of the healthiest oils. It is a vegetable oil that is naturally trans fat-free, cholesterol free, and low in saturated fats. Peanut consumption may improve lipid profiles without promoting weight gain. Peanut oil is used to lower cholesterol and prevent heart disease, to extract the maximum amount of oil we have experimented in varying concentrations of Ammonium sulphate in different dilutions of tertiary-butanol. Varying parameters (like temperature, pH) were analyzed using peanut purchased from the market and the peanut grown through tissue culture. The main purpose of this work was to compare the plants and to provide a method for maximum extraction of peanut oil. Peanut oil is high in unsaturated fats, especially monounsaturated fat, like olive oil. It is also a source of antioxidant, vitamin E and phytosterols, which benefit heart health. Maximum oil production was seen at room temperature having pH 7 and also found maximum in 1:1 concentration (slurry: tertiary butanol). Maximum oil was obtained at 30% ammonium sulphate concentration.

Abstract

The phenotypic characterization of traits associated directly or indirectly with grain yield is a pre requisite for plant breeding program. With an aim to improve the existing varieties with high yielding potentials this experiment was carried out to study the association of twelve yield attributing characters with grain yield and path analysis in 64 rice genotypes of North Bank Plain Zone of Assam. Character association studies indicated that direct selection of 100 grain weight, grain length, grain breadth, biological yield and harvest index, would bring about improvement in grain yield. Path analysis at genotypic and phenotypic level showed filled grains per panicle, effective tillers per plant, 100 grain weight, panicle length, days to maturity and biological yield had positive and high direct effect on grain yield respectively. Hence selection of these traits will be effective for future breeding programs that will simultaneously contribute in improvement of yield.

Abstract

This study describes the preparation of activated carbons from fruit peel waste [Garcinia mangostane peel carbon (GMPC) and Datura stramonium peel carbon (DSPC)] and their application as adsorbents of synthetic alizarin cyanine green (ACG) dye. The different batch adsorption experiments were followed by varying the initial dye concentration, mass of adsorbent, contact time and pH of the medium. The equilibrium adsorption data of ACG dye on GMPC and DSPC were analyzed by Langmuir and Freundlich models. The results indicate that the Freundlich model provides the best correlation of the experimental data. The adsorption capacities of the activated GMPC and DSPC for removal of ACG dye was determined with the Langmuir equation. Adsorption data were modelled using the pseudo-first-order, pseudo-second order and intra-particle diffusion kinetics equations. It was shown that pseudo-first order kinetic equation could best describe the adsorption kinetics. The results of this work showed that indigenously prepared GMPC and DSPC are an excellent environmentally friendly adsorbent for removal of ACG dye from industrial effluents.

Abstract

In this study, the effects of heavy metal (Cd- Cadmium) on the growth hormone (GH) protein of Oreochromis mossambicus (Tilapia) were analyzed. Molecular mechanics protocols are used to explore the 3D structure of the Oreochromis mossambicus and were visualized using advanced molecular visualization tools. The modelled structure was applied to a Metal protein binding server to identify the positions where the amino acids bind with the metal protein. The results clearly elucidated in a graphical manner which amino acid has a high binding affinity with the metal. The results were validated using an Insilico molecular visualization tool which clearly explains the binding positions of the 3D amino acids with Cd present in Oreochromis mossambicus. In conclusion, the molecular interaction between the growth hormone protein of tilapia was observed and it was found that the binding of Cd with the growth hormone inhibits the normal function of the growth of Tilapia. These results play a vital role in understanding the factors affecting the growth of Tilapia in the fish farming sector.

Abstract

Endophytic microorganisms residing in various parts of the plants enhance the growth of the host plant by producing several bioactive compounds and are usually with no associated negative effects. Endophytic bacteria were isolated from the root tubers of the medicinal plant Asparagus racemosus for assessing their plant growth promoting properties. The strains were morphologically and biochemically characterized and screened for Indole 3 acetic acid, ACC deaminase and siderophore production and phosphate solubilisation. Among the 26 strains isolated, four strains such as AR6, AR10, AR11 and AR12 were found to have multiple plant growth promoting properties and were identified as Pseudomonas sp., Priestia sp., Brucella sp. and Enterobacter sp. respectively by morphological, biochemical and 16S rRNA partial gene sequence analysis. All these strains are capable of producing Indole acetic acid, ACC deaminase and siderophore while Priestia sp. and Brucella sp. have the ability to dissolve insoluble phosphate. The highest IAA concentration (310.5µg/mL) was produced by Enterobacter sp. followed by Priestia sp. and Brucella sp. and the production was also confirmed by HPLC analysis. Priestia sp. was found to produce the highest concentration of Siderophore (76.44 units) and have higher capacity to solubilise phosphate than the other strains. The highest ACC deaminase production was shown by Enterobacter sp. The present study indicates that the isolated strains may enhance the growth of the host plant as they possess multiple plant growth promoting properties.

Abstract

Banana is the fourth most important commodity at global level next to rice, wheat and dairy products. It is the earliest fruit known to mankind and has always been an important part of the diet of millions all over the world. It could be considered as 'Poor man's apple' and it is the cheapest among all other fruits in the country. Most of the banana growers are still practicing primitive technologies in crop cultivation. This is primarily due to the reason that there is considerable gab between the technology developed on the research farms and its implementation in the banana field. The transfer of technology is a function of many development factors, training being an important one. Hence, a study was undertaken to identify the training needs of banana growers in crop cultivation. The study was taken up in Erode District of Tamil Nadu State with a sample size of one hundred and twenty growers selected based on random sampling procedure. This study revealed that majority of the respondents expressed high level of training needs for nine major subject matter areas i.e., ‘Plant protection measures’, ‘sucker treatment’, ‘bio-fertilizer application’, ‘marketing’, ‘plant growth regulators’, ‘nutrient management’, ‘micro-nutrient application’, ‘irrigation management’ and ‘weed management’.

Wheat (Triticum aestivum L.) is an important cereal crop for majority of world’s populations. It is the major staple food of about two billion people (36% of the world population). Because of late sowing of wheat crop faces low temperature stress during germination stage. Seed hardening with calcium salt is one the process by which thermotolerance can be induced in seed for better germination, growth and yield. Ca2+ has been found to be involved in the regulation of responses of plants to environmental stresses. Calcium salts namely calcium chloride (CaCl2) and calcium nitrate (Ca(NO3)2) were used for present investigation. Results showed that 15mM CaCl2 was more efficient in up regulating of HSPs and other proteins during low temperature. Seeds hardened with 15mM CaCl2 can influence tolerance against cold temperature during the germination.

Abstract

Dendroclimatology is the branch of dendrochronology for the reconstruction of past climate by using tree-rings as a proxy. In this study, cross-sectional discs of 3 trees in a time span of 1949 to 2012 collected from Nilambur by the College of Forestry, KAU were utilized. This study was to look at teak tree ring chronologies in Nilambur, identify the relationship between tree growth and climate, and ultimately assess the dendroclimatic potential of trees. TSAP-Win software in association with LINTAB was used to measure and cross date the ring width. ARSTAN was used to standardize tree ring data using a tool called cubic smoothing spline to remove the non-climatic signals of the series. The climate data was obtained from CRU TS V.3.21. By using PAST software, a bootstrap correlation with moving intervals was done to determine the relationship between tree growth and climate. The study used monthly rainfall and temperature as the climatic parameters. In general, rainfall showed a positive and temperature showed a negative correlation with tree growth. All chronologies exhibited desired levels of SNR and EPS which are the statistical parameters to determine the dendroclimatological potential of trees, and thus proved the site's high dendroclimatic potential.

Abstract

Oreochromis niloticus or the Nile Tilapia is a cichlid fish which is an inhabitant of North Africa and the Levante area, including Israel, and Lebanon. In this In silico research investigation, two major findings are involved. We, first, analyze the protein sequence in the growth hormone of Oreochromis niloticus in order to identify the motif regions present in the sequence. Next, we predict the 3D structure of the protein sequence and then analyze the heavy metal binding sites, particularly, Mercury (Hg) present in it. In methodology, we use NCBI database to retrieve the protein sequence of the sps. in FASTA format. The retrieved sequence was analyzed for molecular functional details (motifs) using motif and domain servers. The 3D structure was explored using automated homology modelling servers and was applied into a metal-binding identification tool. Our results clearly explain that, in the protein sequence of the growth hormone of Oreochromis niloticus, the heavy metal, Mercury, binds with the functional part along with various other regions of the protein. Hence, we strongly conclude that the non-essential heavy metal, Mercury, is directly involved in the inhibition of the growth hormone of Oreochromis niloticus. The results obtained from our study play a vital role in rescuing aquatic species from the harmful effects of heavy metals.

Abstract

The water is an essential natural resource for sustaining life and environment but over the last few decades the water quality is deteriorating due to it is over exploitation. Limestone rock mining in the district started about a decade ago to meet the requirements of the cement plants of the area. In recent years, number of cement plants and quantum of limestone mining have increased drastically leading to severe environmental problems ranging from deforestation and degradation of land to water pollution and water scarcity. This study reports the impact of limestone mining on water quality based on analyses of various physico-chemical parameters of water samples of the area and its comparison with the results of unaffected water body. The physico-chemical status of water samples from ten major part of locality in Sankari was assessing. The sampling points were selected based on their importance. The physicochemical parameter like, temperature, pH, electrical conductivity (EC), total dissolved solids (TDS), total alkalinity (TA), total hardness (TH), calcium (Ca) magnesium (Mg), sodium (Na), potassium (K), chloride (Cl), fluoride (F), nitrate (NO3) sulphates (SO4) and phosphate (PO4) of Open Well and Bore well was determined. The results were compared with standards prescribed by WHO (1973) and ISI (10500-91). It was found that the ground water was contaminated at few sampling sites namely Karumapurathanur, Sankari, ICL Colony and Kasthuripatti While the sampling sites Devannagoundanur, Chinnagoundanur, ICL Plant, Veerachipalaiyam, Sanniyasipatti and Padaiveedu showed physicochemical parameters within the water quality standards and the quality of water is good and it is fit for drinking purpose.

Abstract

Revolutionary advancement in technology has resulted in an increase in food production and also there is a tremendous loss of stored food products annually due to the destruction of them by various storage pests. Thousands of plant products with insecticidal properties have been identified so far. The present study was aimed to test the efficacy of protein fractions of Pisum sativum as a potential insecticidal agent in the management and regulation of storage pest, Tribolium castaneum as well as its use as an anti-microbial agent. Purified protein fractions of three different concentrations, 0.25g, 0.5g and 1.0g repeated five times, were mixed with the 10g feed, into which five pairs of Tribolium castaneum adults from a stock culture were released. The trends in their mortality were observed over a period of 7 days. The results of the study revealed a positive relation between the concentration of protein fractions and the average mortality rate of adult pests. Biochemical analysis of the treated insects also revealed a significant reduction in their metabolic rates. Besides, promising results were also obtained on the assessment of anti-microbial properties exhibited by the same against pathogenic inoculums of Streptococcus pneumonia, Salmonella typhii and E. coli.

Abstract

Lion Tailed Macaque is believed to be the forebear of all Asian macaques. Wanderoo macaque is endemic to the Western Ghats and has been observed in the regions of Karnataka, Kerala and Tamil Nadu. It draws the attention of scientists and researchers because of its K- strategy of populace growth and a unique characteristic, of evolution. This species has a very less populace and is also listed on the IUCN Red List of endangered species due to various anthropogenic activities. The Evolutionary tree helps in better understanding the behavioral personae of the macaque along with its familial history. A Phylogenetic tree has been constructed with Mega X software and the fallouts have been interpreted to apprehend the evolutionary antiquity of the macaque.

Abstract

During present investigation authors collected the monotypic genus Leptosiropsis Jao from two different sites of Supaul district of North Bihar. Earlier the genus was also reported from Bihar by [5-6]. It was also reported by [5], [7] from West Bengal. Hence it is evident that it occurs frequently in some parts of eastern Bihar. Apart from Bihar it was reported from Lucknow by [2-3]. Hence distribution pattern of the genus Leptosiropsis Jao reflects its very restricted occurrence. A critical study is needed to ascertain that whether it is due to ecological factors or our poor state of exploration. Lack of plasticity in morphological characters is another point to pay attention because all specimens reported from different localities so far show very little variation in dimension or other characters. Hence a further intense study is needed to understand the nature and systematic position of this rare taxon. During the taxonomic investigations of freshwater filamentous green algae of Supaul district of North Bihar, the authors recorded a good number of Chaetophoralean algae. In this communication a rare monotypic genus Leptosiropsis (type species: L. torulosa Jao) is described and illustrated.
