With ongoing global climate change, water scarcity-induced drought stress remains a major threat to agricultural productivity. Plants undergo a series of physiological and morphological changes to cope with drought stress, including stomatal closure to reduce transpiration and changes in root architecture to optimize water uptake. Combined phenotypic and multi-omics studies have recently identified a number of drought-related genetic resources in different crop species. The functional dissection of these genes using molecular techniques has enriched our understanding of drought responses in crops and has provided genetic targets for enhancing resistance to drought. Here, we review recent advances in the cloning and functional analysis of drought resistance genes and the development of technologies to mitigate the threat of drought to crop production.
随着全球气候变化的持续，水资源短缺引发的干旱胁迫仍然是农业生产力面临的主要威胁。植物会经历一系列生理和形态变化来应对干旱胁迫，包括气孔关闭以减少蒸腾作用，以及根系结构变化以优化水分吸收。最近，结合表型和多组学研究在不同作物品种中鉴定出了许多与干旱相关的遗传资源。利用分子技术对这些基因进行功能解析，丰富了我们对作物干旱反应的理解，并为增强抗旱性提供了遗传靶点。在此，我们综述了抗旱基因克隆与功能分析的最新进展以及减轻干旱对作物生产威胁的技术发展。
