Hydrogen sulfide (HS) is regarded as a "New Warrior" for managing plant stress. It also plays an important role in plant growth and development. The regulation of root system architecture (RSA) by HS has been widely recognized. Plants are dependent on the RSA to meet their water and nutritional requirements. They are also partially dependent on the RSA for adapting to environment change. Therefore, a good understanding of how HS affects the RSA could lead to improvements in both crop function and resistance to environmental change. In this review, we summarized the regulating effects of HS on the RSA in terms of primary root growth, lateral and adventitious root formation, root hair development, and the formation of nodules. We also discussed the genes involved in the regulation of the RSA by HS, and the relationships with other signal pathways. In addition, we discussed how HS regulates root growth in response to abiotic stress. This review could provide a comprehensive understanding of the role of HS in roots during development and under abiotic stress.
硫化氢（HS）被视为管理植物应激的“新战士”。它在植物生长和发育中也起着重要作用。HS 对根系结构（RSA）的调节已得到广泛认可。植物依赖 RSA 来满足其对水和营养的需求。它们部分也依赖 RSA 来适应环境变化。因此，深入了解 HS 如何影响 RSA 可能会提高作物功能和对环境变化的抗性。在这篇综述中，我们总结了 HS 对主根生长、侧根和不定根形成、根毛发育以及根瘤形成等方面对 RSA 的调节作用。我们还讨论了 HS 调节 RSA 的相关基因，以及与其他信号通路的关系。此外，我们还讨论了 HS 如何调节根的生长以响应非生物胁迫。这篇综述可以提供对 HS 在发育过程中和非生物胁迫下根系中的作用的全面理解。
