摘要

硫化氢(H2S)是植物中一种新兴的多任务细胞信号分子,通常被认为是仅次于一氧化氮和一氧化碳的第三种气体传递素。越来越多的证据表明H2S具有许多生物学功能,包括种子萌发、植物生长、生理以及防御反应的调节。虽然植物在硫同化过程中产生H2S已经知道了很长一段时间,但我们对H2S的完整合成和信号作用的了解最近才开始出现。最近的一些报道指出,植物细胞中H2S的控制释放是在非生物胁迫条件下存活的重要信号。此外,H2S启动还通过重建氧化还原稳态、维持离子平衡、增强渗透物积累、调节基因表达等方式诱导机体对一系列非生物胁迫条件的抗性。此外,越来越多的证据表明H2S信号与植物激素、过氧化氢、一氧化氮和其他信号分子相互作用。然而,目前关于H2S介导的翻译后修饰、S -巯基化及其对植物蛋白质活性的直接影响的研究仍处于起步阶段。随着H2S在植物中的重要性日益增加,以及我们对其功能和靶点的认识不足,在充分认识其在植物抗逆性中的信号作用之前,需要在生理、生化和分子水平上进行进一步的详细分析。

Hydrogen Sulfide in Plant Abiotic Stress Tolerance
Hydrogen sulfide (H2S) is an emerging, multitasking cell signaling molecule in plants often considered as third gasotransmitter after nitric oxide and carbon monoxide. Accumulating evidence has imparted many biological functions to H2S including seed germination, plant growth, and physiology as well as the moderation of defense responses. While its production in plants during sulfur assimilation has been known for quite a while, our knowledge of the complete synthesis and signaling role of H2S only started emerging recently. Several recent reports have pointed the controlled release of H2S in plant cells as a crucial signal for the survival under abiotic stress conditions. Besides, H2S priming also induce systemic resistance against a range of abiotic stress conditions majorly by reestablishment of redox homeostasis, maintaining ion balance, enhancing osmolyte accumulation, regulating gene expression. Additionally, mounting evidence indicates that H2S signaling interacts with plant hormones, hydrogen peroxide, nitric oxide, and other signaling molecules. However, current research on the role of H2S mediated post translational modification, S‐sulfhydration, and its direct effects on the activity of proteins is still in its infancy in plants. The growing importance of H2S and our insufficient knowledge on its functions and targets in plants calls for further detailed analyses at the physiological, biochemical and molecular levels before fully accepting its signaling roles in plant stress tolerance.
