Insufficient food availability, increasing population, poverty, malnutrition, and depletion of natural resources may lead to a global food crisis. Stable and greater production of nutritious food crops may be an alternative to overcome these difficulties. Mung bean ( Vigna radiata ) is an important food legume with an excellent source of easily digestible protein. It is also recommended for health benefits due to the presence of bioactive compounds. Short life cycle and nitrogen fixing ability makes it suitable for major cropping system. Mung bean is highly sensitive towards various abiotic and biotic stress factors prevailing in the environment. The present review focuses on drought and salinity stress as major abiotic stresses limiting mung bean production. It includes adverse effects, mung bean response, management strategies, and significant efforts made towards these challenges. In this review, the need of addressing the current demand on modern agriculture and food production activities impaired by global climate change has been focused.","PeriodicalId":8135,"journal":{"name":"Annals of Plant Sciences","volume":"83 1","pages":"3899-3906"},"PeriodicalIF":0.0,"publicationDate":"2020-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77567883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Besides this they improve the growth and yield of crop and the quality parameters. Nano-fertilizers are very effective for precise nutrient management in precision agriculture with matching the crop growth stage for nutrient and may provide nutrient throughout the crop growth period. However, it has also been speculated that nano-fertilizers can increase the crop growth up to certain optimum concentrations, further increase in concentration may cause nutrient toxicity thereby inhibiting the crop growth. It is also necessary to assess the effect of slow release nano-fertilizer on the soil enzyme activity and soil microbial population. The introduction of nano-fertilizers into the natural environment may pose threat to beneficial microbial communities. The impact of nano-fertilizers on microbial activity could be determined through measurement of soil respiration and enzymatic activities. This review would therefore focus on the effect of nano-fertilizers on the activity of soil microorganisms including both their beneficial and deleterious effects.","PeriodicalId":8135,"journal":{"name":"Annals of Plant Sciences","volume":"111 1","pages":"3846-3859"},"PeriodicalIF":0.0,"publicationDate":"2020-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89448585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Seed and soil health are important in growing crop. Seeds of Pearl millet in different concentration of effluent (0, 10, 50 and 100 %) have been treated to study germination and mycoflora grown during germination. Increased seed mycoflora were found in 50% treatment ( Aspergillus niger , A. flavus, A. terreus, Penicillium verruculosum , Fusarium oxysporum , and Curvularia lunata ). Aspergillus flavus were common in 100 %, 10, %, and control (0%). Percent germination was 0 % in 100 % effluent treatment. Highest percent germination was reported in control (86%) followed by 10 % (48 %), and 50 % effluent treatment (24 %)). The rhizosphere and non-rhizosphere mycoflora of Pearl millet at different growth period (15, 30, 45, and 90 day) were studied with different concentration of sugar factory effluent, (0, 10,50 and 100 %) following serial dilution plate method, (Timonin, 1940). Species of Aspergillus, Fusarium and Penicillium were very commonly isolated from the rhizosphere. The rhizosphere mycoflora was very high at flowering stage of plant growth i.e. the microbial population was increased with age of plant up to flowering stage then it was decreased. Qualitatively 16 fungal species were recorded from the rhizosphere and soil. It is seen that Aspergillus niger , A. flavus , A. fumigatus , A. nidulans , A. terreus , Alterneria sp., Penicillium funiculosum , Rhizoctonia bataticola, Rhzopus stolonifera were dominant both in the rhizosphere and soil. The species like Cladosporium oxysporum , A. ustu s, curvularia lunata , Helminthosprium sp., Mucor sp., Aspergillus acculeaus and Trichothecium sp. were occurred randomly. Results on an average basis indicated that Aspergillus niger , A. fumigatus, A. ustus , Curvularia lunata , Fusarium oxysporum , Mucor sp . Penicillium f uniculosum , and Trichothecium roseum appeared to be stimulated due to effluents whereas species like Aspergillus nidulans , Aspergillus terreus , Alterneria sp., Cladosporium oxysprum , Rhizopus s tolonifera , Torula sp., and Aspergillus acculeatus were found to be inhibited due to effluent treatment.

Glyoxalase enzymes play the key role in MG detoxification and help the plant to survive. The glyoxalase system of Rhizophora mucronata Lam. was decoded; characterized and salt dependant increase in gene expression was analyzed in our previous studies ( GenBank Accessions GGEC01061405, GGEC01044968, and GGEC01022591) . In order to utilize these stress responsive genes in crop improvement, it is needed to monitor their methylglyoxal detoxification efficiency in vivo . For this, over expression of the glyoxalase enzyme(s) in a model/cop plant system can be done. Construction of a binary vector carrying coding region of glyoxalase gene(s) which can replicate both in E coli and Agrobacterium tumefaciens is the prime step in plant transformation research. In the present study in silico cloning of glyoxalase I, II and III specific to R. mucronata (Rm GLY I, Rm GLY II and Rm GLY III) were performed into pBA 002 plant expression vector carrying 6x myc insert. The binary vector is linearized with BSrG1 restriction enzyme. Cloning primers for all the three glyoxalase coding regions with 5’ end terminal homology to the linear myc pBA were synthesized and validated in vitro . To account for in silico cloning, the Rm GLY I insert was successfully cloned via homologous recombination into myc pBA. The presence of Rm GLYI insert in the final construct was confirmed by colony PCR and sequence analysis.","PeriodicalId":8135,"journal":{"name":"Annals of Plant Sciences","volume":"14 1","pages":"3834-3842"},"PeriodicalIF":0.0,"publicationDate":"2020-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88337195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
