Drought has been highly prevalent around the world especially in Sub-Saharan Africa and South-East Asian countries. Consistent climatic instabilities and unpredictable rainfall patterns are further worsening the situation. Rice is a C3 staple cereal and an important food crop for the majority of the world's population and drought stress is one of the major growth retarding threats for rice that slashes down grain quality and yield. Drought deteriorates rice productivity and induces various acclimation responses that aids in stress mitigation. However, the complexity of traits associated with drought tolerance has made the understanding of drought stress-induced responses in rice a challenging process. An integrative understanding based on physiological adaptations, omics, transgenic and molecular breeding approaches successively backed up to developing drought stress-tolerant rice. The review represents a step forward to develop drought-resilient rice plants by exploiting the knowledge that collaborates with omics-based developments with integrative efforts to ensure the compilation of all the possible strategies undertaken to develop drought stress-tolerant rice.

提高水稻的耐旱性:通过多维方法确保粮食安全

干旱在世界各地非常普遍,特别是在撒哈拉以南非洲和东南亚国家。持续的气候不稳定和不可预测的降雨模式使情况进一步恶化。水稻是一种 C3 主食谷物,也是世界上大多数人口的重要粮食作物,干旱胁迫是导致水稻生长迟缓的主要威胁之一,会降低谷物质量和产量。干旱会降低水稻的生产力并引发各种有助于缓解压力的适应反应。然而,与耐旱性相关的性状的复杂性使得对水稻干旱胁迫诱导反应的理解成为一个具有挑战性的过程。基于生理适应、组学、转基因和分子育种方法先后支持开发耐旱水稻。该审查代表了通过利用与基于组学的开发合作的知识以及综合努力来确保开发抗旱水稻的所有可能策略的汇编,从而开发抗旱水稻植物。本文受版权保护。版权所有。
