Research Progress and Perspective on Drought Stress in Legumes: A Review

International Journal of Molecular Sciences, Journal Year: 2019, Volume and Issue: 20(10), P. 2541 - 2541

Published: May 23, 2019

Climate change, food shortage, water scarcity, and population growth are some of the threatening challenges being faced in today's world. Drought stress (DS) poses a constant challenge for agricultural crops has been considered severe constraint global productivity; its intensity severity predicted to increase near future. Legumes demonstrate high sensitivity DS, especially at vegetative reproductive stages. They mostly grown dry areas moderately drought tolerant, but DS leads remarkable production losses. The most prominent effects reduced germination, stunted growth, serious damage photosynthetic apparatus, decrease net photosynthesis, reduction nutrient uptake. To curb catastrophic effect legumes, it is imperative understand effects, mechanisms, agronomic genetic basis sustainable management. This review highlights impact on proposes appropriate management approaches alleviate stress. In our discussion, we outline influence physiological aspects (such as uptake), parameters yield. Additionally, various strategies, instance, practices (planting time geometry, management), plant growth-promoting Rhizobacteria arbuscular mycorrhizal fungal inoculation, quantitative trait loci (QTLs), functional genomics advanced strategies (CRISPR-Cas9) also critically discussed. We propose that integration several such biotechnological well genome editing tools needed develop drought-tolerant legume cultivars.

Meta‐analysis of drought and heat stress combination impact on crop yield and yield components

Physiologia Plantarum, Journal Year: 2020, Volume and Issue: 171(1), P. 66 - 76

Published: Sept. 3, 2020

Episodes of prolonged drought coupled with heat waves (i.e. and combination) can have a devastating impact on agricultural production crop yield. It is therefore not surprising that improving tolerance to combination has been major goal for breeders biotech companies. Although much known about the physiological molecular responses vegetative tissues stress, less this stress yield different components. Here, we used meta‐analysis approach synthesize results from over 120 published case studies combined stress. Our findings reveal significantly impacts by decreasing harvest index, shortening life cycle crops, altering seed number, size composition. Furthermore, these are more severe when applied during reproductive stage plants. We further identify differences in how legumes cereals respond utilizing C3 or C4 metabolism may provide an advantage plants combinations. Taken together our study highlights need focus future studies, as well breeding efforts, at species.

Published: June 22, 2020

Abstract Background Incidences of heat stress due to the changing global climate can negatively affect growth and yield temperature-sensitive crops such as soybean variety, Pungsannamul. Increased temperatures decrease crop productivity by affecting biochemical, physiological, molecular, morphological factors either individually or in combination with other abiotic stresses. The application plant growth-promoting endophytic bacteria (PGPEB) offers an ecofriendly approach for improving agriculture production counteracting negative effects stress. Results We isolated, screened identified thermotolerant B. cereus SA1 a bacterium that could produce biologically active metabolites, gibberellin, indole-3-acetic acid, organic acids. inoculation improved biomass, chlorophyll content, fluorescence plants under normal conditions 5 10 days. Heat increased abscisic acid (ABA) reduced salicylic (SA); however, markedly ABA SA. Antioxidant analysis results showed ascorbic peroxidase, superoxide dismutase, glutathione contents plants. In addition, decreased amino contents; they were inoculation. days shock protein (HSP) expression, GmHSP expression was observed after days; augmented response HSP expression. stress-responsive GmLAX3 GmAKT2 overexpressed SA1-inoculated may be associated reactive oxygen species generation, altered auxin stimuli, enhanced potassium gradients, which are critical Conclusion current findings suggest used mitigation damage commercialized biofertilizer only case found non-pathogenic.

Mechanistic insights on melatonin‐mediated drought stress mitigation in plants

Physiologia Plantarum, Journal Year: 2020, Volume and Issue: 172(2), P. 1212 - 1226

Published: Dec. 11, 2020

Abstract Drought stress imposes a serious threat to crop productivity and nutritional security. adaptation mechanisms involve complex regulatory network comprising of various sensory signaling molecules. In this context, melatonin has emerged as potential molecule playing crucial role in imparting tolerance plants. Melatonin pretreatment regulates plant physiological processes such osmoregulation, germination, photosynthesis, senescence, primary/secondary metabolism, hormonal cross‐talk under water deficit conditions. Melatonin‐mediated regulation ascorbate‐glutathione (AsA–GSH) cycle plays scavenge reactive oxygen species generated the cells during drought.
