Gaseous molecules, such as hydrogen sulfide (H S) and nitric oxide (NO), are crucial players in cellular and (patho)physiological processes in biological systems. The biological functions of these gaseous molecules, which were first discovered and identified as gasotransmitters in animals, have received unprecedented attention from plant scientists in recent decades. Researchers have arrived at the consensus that H S is synthesized endogenously and serves as a signaling molecule throughout the plant life cycle. However, the mechanisms of H S action in redox biology is still largely unexplored. This review highlights what we currently know about the characteristics and biosynthesis of H S in plants. Additionally, we summarize the role of H S in plant resistance to abiotic stress. Moreover, we propose and discuss possible redox-dependent mechanisms by which H S regulates plant physiology.
气态分子，如硫化氢（H2S）和一氧化氮（NO），是生物系统中细胞和（病理）生理过程中的关键参与者。这些气态分子的生物学功能最初在动物中被发现并鉴定为气体信号分子，近年来受到植物科学家的空前关注。研究人员已经达成共识，即 H2S 是内源性合成的，并在植物整个生命周期中作为信号分子发挥作用。然而，H2S 在氧化还原生物学中的作用机制在很大程度上仍未得到探索。本综述重点介绍了我们目前对植物中 H2S 的特性和生物合成的了解。此外，我们总结了 H2S 在植物抵御非生物胁迫中的作用。此外，我们提出并讨论了 H2S 调节植物生理学的可能的依赖于氧化还原的机制。
