Climate Change and the Incidence of Drought and Heat Stress in Agriculture
摘要
One of the main global concerns is the gradual rise in temperature brought on by human activity. Plant development is negatively impacted by the resulting heat (HS) and drought stress (DS), endangering ecosystem quality, and global food security at jeopardy. Plant growth, physiological processes, and yield are all impacted by HS and DS due to the physical damage, physiological disruptions, and biochemical changes that happen at distinct stages of growth. Thus, a deeper comprehension of how plants respond to HS/DS has practical ramifications for developing defence mechanisms, mitigating tactics, and recognizing the distinctions between HS/DS and the accompanying drought stress. To create HS/DS-tolerant genotypes in crops grown for food or feed, conventional breeding, biotechnological, and molecular methods are utilized. The molecular mechanisms behind HS/DS are now better understood thanks to recent advancements in omics methods. To increase plant resilience to HS, smart crop practice management is still beneficial. Proper timing of seeding, priming the seed, treating the seed with bacteria, controlling water and nutrients, applying osmo-protectants exogenously, and preserving soil moisture are crucial strategies for enhancing plant behavior in the critical habitat situations brought about by climate change and warming of the planet.
