Drought stress leads to a significant amount of agricultural crop loss. Thus, with changing climatic conditions, it is important to develop resilience measures in agricultural systems against drought stress. Roots play a crucial role in regulating plant development under drought stress. In this review, we have summarized the studies on the role of roots and root-mediated plant responses. We have also discussed the importance of root system architecture (RSA) and the various structural and anatomical changes that it undergoes to increase survival and productivity under drought. Various genes, transcription factors, and quantitative trait loci involved in regulating root growth and development are also discussed. A summarization of various instruments and software that can be used for high-throughput phenotyping in the field is also provided in this review. More comprehensive studies are required to help build a detailed understanding of RSA and associated traits for breeding drought-resilient cultivars.
干旱胁迫导致大量农业作物减产。因此，随着气候条件的变化，开发农业系统对干旱胁迫的恢复力措施非常重要。根在调节植物对干旱胁迫的发育中起着至关重要的作用。在这篇综述中，我们总结了关于根和根介导的植物响应的研究。我们还讨论了根系结构（RSA）的重要性以及它在增加干旱条件下的生存和生产力方面所经历的各种结构和解剖变化。还讨论了参与调节根生长和发育的各种基因、转录因子和数量性状位点。本文综述还提供了可用于田间高通量表型分析的各种仪器和软件的总结。需要更全面的研究来帮助深入了解 RSA 及其相关性状，从而培育抗旱品种。
