Plant Biology, Год журнала: 2020, Номер 23(S1), С. 50 - 57

Опубликована: Авг. 3, 2020

With continued climate changes, soil drought stress has become the main limiting factor for crop growth in arid and semi-arid regions. A typical characteristic of is burst reactive oxygen species (ROS), causing oxidative damage. Plant-associated microbes, such as arbuscular mycorrhizal fungi (AMF), can regulate physiological molecular responses to tolerate stress, they have a strong ability cope with drought-induced damage via enhanced antioxidant defence systems. AMF produce limited arbuscule-containing root cortical cells. Similar plants, modulate fungal network enzymatic (e.g. GmarCuZnSOD GintSOD1) non-enzymatic GintMT1, GinPDX1 GintGRX1) systems scavenge ROS. Plants also respond mycorrhization enhance tolerance metabolites induction genes. The present review provides an overview plant - fungus dialogue mitigating stress. Future studies should involve identifying genes transcription factors from both host plants response utilize transcriptomics, proteomics metabolomics clarify clear mechanism between burst.

One of the most chronic constraints to crop production is grain yield reduction near harvest stage by lodging worldwide. This more prevalent in cereal crops, particularly wheat and rice. Major factors associated with involve morphological anatomical traits along chemical composition stem. These have built up remarkable relationship rice genotypes either prone or displaying resistance. In this review, we made a comparison our conceptual perceptions foregoing published reports proposed fundamental controlling techniques that could be practiced control devastating effects stress. The management stress is, however, reliant on chemical, agronomical, genetic are reducing risk threat But, still, there many questions remain answered elucidate complex phenomenon, so agronomists, breeders, physiologists, molecular biologists require further investigation address challenging problem.

Опубликована: Ноя. 10, 2022

Breeding crop plants with increased yield potential and improved tolerance to stressful environments is critical for global food security. Drought stress (DS) adversely affects agricultural productivity worldwide expected rise in the coming years. Therefore, it vital understand physiological, biochemical, molecular, ecological mechanisms associated DS. This review examines recent advances plant responses DS expand our understanding of DS-associated mechanisms. Suboptimal water sources affect growth yields through physical impairments, physiological disturbances, biochemical modifications, molecular adjustments. To control devastating effect plants, important its consequences, mechanisms, agronomic genetic basis sustainable production. In addition responses, we highlight several mitigation options such as omics approaches, transgenics breeding, genome editing, mechanical methods (foliar treatments, seed priming, conventional practices). Further, have also presented scope speed breeding platforms helping develop drought-smart future crops. short, recommend incorporating multi-omics, traditional strategies, cultivars achieve 'zero hunger' goal.

Hormonal impact on photosynthesis and photoprotection in plants

PLANT PHYSIOLOGY, Год журнала: 2021, Номер 185(4), С. 1500 - 1522

Опубликована: Янв. 1, 2021

Abstract Photosynthesis is not only essential for plants, but it also sustains life on Earth. Phytohormones play crucial roles in developmental processes, from organ initiation to senescence, due their role as growth and regulators, well central the regulation of photosynthesis. Furthermore, phytohormones a major photoprotection photosynthetic apparatus under stress conditions. Here, addition discussing our current knowledge auxin, cytokinins, gibberellins, strigolactones promoting photosynthesis, we will highlight abscisic acid beyond stomatal closure modulating photosynthesis various conditions through crosstalk with ethylene, salicylates, jasmonates, brassinosteroids. controlling production scavenging photosynthesis-derived reactive oxygen species, duration extent photo-oxidative redox signaling be discussed detail. Hormones have significant impact processes plants both optimal conditions, hormonal interactions, complementation, being important spatiotemporal integrative during development at whole-plant level.

Drought Stress in Grain Legumes: Effects, Tolerance Mechanisms and Management

Agronomy, Год журнала: 2021, Номер 11(12), С. 2374 - 2374

Опубликована: Ноя. 23, 2021

Grain legumes are important sources of proteins, essential micronutrients and vitamins for human nutrition. Climate change, including drought, is a severe threat to grain legume production throughout the world. In this review, morpho-physiological, physio-biochemical molecular levels drought stress in described. Moreover, different tolerance mechanisms, such as morphological, mechanisms legumes, also reviewed. various management approaches mitigating effects assessed. Reduced leaf area, shoot root growth, chlorophyll content, stomatal conductance, CO2 influx, nutrient uptake translocation, water-use efficiency (WUE) ultimately affect yields. The yield loss varies from species species, even variety within depending upon severity several other factors, phenology, soil textures agro-climatic conditions. Closure stomata leads an increase temperature by reducing transpiration rate, and, so, plant faces another under stress. biosynthesis reactive oxygen (ROS) most detrimental effect Legumes can adapt changing their morphology, physiology mechanism. Improved system architecture (RSA), reduced number size leaves, stress-induced phytohormone, closure, antioxidant defense system, solute accumulation (e.g., proline) altered gene expression play crucial role tolerance. Several agronomic, breeding both conventional molecular, biotechnological used practices developing drought-tolerant without affecting crop yield. Exogenous application plant-growth regulators (PGRs), osmoprotectants inoculation Rhizobacteria arbuscular mycorrhizal fungi promotes legumes. Genome-wide association studies (GWASs), genomic selection (GS), marker-assisted (MAS), OMICS-based technology CRISPR/Cas9 make work easy save time developmental cycle get resistant drought-resistant chickpea, faba bean, common bean pigeon pea, were developed institutions. Drought-tolerant transgenic example, chickpeas, introgressing desired genes through approaches. quantitative trait loci (QTLs), candidate occupying traits, identified but not all proper implementation. Hence, more research should be conducted improve traits avoiding losses during drought.
