Drought Stress in Plants: Causes, Consequences, and Tolerance
2016年5月26日 · Drought stress is a multidimensional stress and causes changes in the physiological, morphological, biochemical, and molecular traits in plants. Many plants have improved their resistance mechanisms to tolerate drought stress, but these mechanisms are varied and depend on the plant species.
A review on drought stress in plants: Implications, mitigation and the ...
2021年9月1日 · Drought stress is one such abiotic stress which causes major setbacks to agricultural productivity every year. Water scarcity due to decline in rainfall and increased frequency of dry spells give rise to drought conditions. Often drought is accompanied by other detrimental effects like salinity, heat and attack of pathogens.
The physiology of plant responses to drought | Science - AAAS
2020年4月17日 · From the perspective of molecular biology, cellular water loss marks the first event of drought stress. At the cellular level, drought signals promote production of stress-protectant metabolites such as proline and trehalose, trigger the antioxidant system to maintain redox homeostasis, and deploy peroxidase enzymes to prevent acute cellular ...
Plant drought stress: effects, mechanisms and management
Drought stress reduces leaf size, stem extension and root proliferation, disturbs plant water relations and reduces water-use efficiency. Plants display a variety of physiological and biochemical responses at cellular and whole-organism levels towards prevailing drought stress, thus making it a complex phenomenon.
Drought Stress Responses and Resistance in Plants: From Cellular ...
2020年9月9日 · In this review, we summarize recent advances in research on drought stress responses, focusing on long-distance signaling from roots to shoots, ABA synthesis and transport, and metabolic regulation in both cellular and whole-plant levels of Arabidopsis and crops.
Widespread and complex drought effects on vegetation ... - Nature
2023年8月15日 · Increased VOD ratio suggests that drought stress leads to reduced stomatal conductance and relatively higher vegetation water content during the day than the night.
Down-to-earth drought resistance | Nature Plants
2024年4月23日 · As mild drought stress affects a large proportion of drought-prone rice-growing areas in the world, a laboratory experiment that applies severe stress treatment can hardly be expected to...
Crop traits and production under drought - Nature
2024年2月6日 · Drought limits crop productivity and threatens global food security, with moderate drought stress — when crops grow at a reduced rate — commonly experienced.
Drought Stress Impacts on Plants and Different Approaches to
2021年1月28日 · Among the abiotic stresses, drought stress is gaining attention due to its adverse effect on plant growth and development and significant reduction in plant yield and biomass causing global food insecurity. Drought stress affects plants through the life cycle i.e., from germination till maturity.
