Drought is considered one of the major limiting factors for crop production. Drought-affected areas are consistently expanding. As rice stands as a primary grain widely consumed as a staple food by people across the globe, with a particular prominence in Asian countries. Due to its short root structure, thin cuticular wax layer and quick stomatal closure, rice is considered as drought-sensitive crop. The impact of drought on rice amplifies with plant growth and its adverse effects are more pronounced during the reproductive phase, including stages such as blooming, filling and maturity. Every year rice growers are facing a considerable deterioration of yield due to abiotic stresses specially drought. To address this undesirable consequences, multi-omics approaches are successfully being utilized as a mitigation strategy. A thorough, precise and systematic comprehension of the fundamental biological and cellular mechanisms activated by crop plants during stress is achieved through a range of omics technologies, including genomics, transcriptomics, proteomics and metabolomics. The integration of multi omics approaches offers a holistic understanding of cellular dynamics during drought or other stress conditions. These omics-based tools can identify and manipulate drought-tolerant genes. Utilizing omics approaches to stack these genes in rice contributes to the development of a drought resistant plant architecture. This review article aims to compile the latest published strategies on the application of multi omics approaches to accelerate the development of drought-tolerant rice plants.
干旱被认为是作物生产的主要限制因素之一。受干旱影响的地区一直在扩大。由于水稻是全球人们广泛食用的主要谷物，在亚洲国家尤为突出。由于其根系结构短、表皮蜡层薄和气孔关闭快，水稻被认为是对干旱敏感的作物。干旱对水稻的影响随着植株生长而加剧，其不利影响在生殖阶段更为明显，包括开花、灌浆和成熟等阶段。每年，水稻种植者都面临着由于非生物胁迫特别是干旱导致的产量大幅下降。为了解决这一不良后果，多组学方法正被成功地用作一种缓解策略。通过一系列组学技术，包括基因组学、转录组学、蛋白质组学和代谢组学，可以全面、精确和系统地理解作物在胁迫期间激活的基本生物学和细胞机制。多组学方法的整合提供了对干旱或其他胁迫条件下细胞动态的整体理解。这些基于组学的工具可以识别和操纵耐旱基因。利用组学方法将这些基因整合到水稻中有助于培育耐旱的植株结构。这篇综述文章旨在汇编最新发表的关于应用多组学方法加速耐旱水稻植株开发的策略。
