Hydrogen sulfide (HS) is considered the third gas signal molecule in recent years. A large number of studies have shown that HS not only played an important role in animals but also participated in the regulation of plant growth and development and responses to various environmental stresses. Waterlogging, as a kind of abiotic stress, poses a serious threat to land-based waterlogging-sensitive plants, and which HS plays an indispensable role in response to. In this review, we summarized that HS improves resistance to waterlogging stress by affecting lateral root development, photosynthetic efficiency, and cell fates. Here, we reviewed the roles of HS in plant resistance to waterlogging stress, focusing on the mechanism of its promotion to gained hypoxia tolerance. Finally, we raised relevant issues that needed to be addressed.
硫化氢（HS）是近年来被认为的第三种气体信号分子。大量研究表明，HS不仅在动物中发挥重要作用，还参与植物生长发育的调控以及对各种环境胁迫的响应。涝害作为一种非生物胁迫，对陆生的涝害敏感植物构成严重威胁，而HS在植物对涝害的响应中发挥着不可或缺的作用。在本综述中，我们总结了HS通过影响侧根发育、光合效率和细胞命运来提高对涝害胁迫的抗性。在此，我们综述了HS在植物抗涝害胁迫中的作用，重点关注其促进植物获得耐缺氧能力的机制。最后，我们提出了一些需要解决的相关问题。
