摘要: 硫化氢(H2S)是继一氧化碳(CO)和一氧化氮(NO)后植物体内发现的第三种气体信号分子,参与种子萌发、植物生长发育及耐逆性的获得等生理过程。干旱是限制作物产量的最主要的环境胁迫因子。近年来,H2S也已被证实参与植物耐旱性的形成。结合最新的研究进展,在讨论H2S信号与其它信号分子如活性氧(ROS)、NO、CO、脱落酸(ABA)、乙烯(ETH)、microRNAs等交互作用的基础上,从气孔运动、渗透调节物质、抗氧化系统、甲基乙二醛脱毒系统、热激蛋白等方面,综述了H2S诱导植物耐旱性形成的可能机理,并提出了未来的研究方向。进一步拓展了H2S信号的生理功能和植物耐旱性形成的机理,对深入研究H2S与植物耐逆性包括耐旱性的关系,具有重要的指导意义。

Abstract: Hydrogen sulfide(H2S)is found to be the third gaseous signal molecule after carbon monoxide(CO)and nitric oxide(NO)in plants,which involves in many physiological processes such as seed germination,plant growth and development,and the acquisition of stress tolerance. Drought stress is the major environmental stress factor that limits crop plant yield. Recently,the fact that H2S involves in the formation of drought tolerance also has been identified in various plant species. Based on the current progress in H2S field,crosstalk between H2S signal and other signals,such as reactive oxygen species(ROS),NO,CO,abscisic acid(ABA),ethylene(ETH),and microRNAs is discussed. Further,the possible mechanisms of H2S inducing the formation of drought tolerance are summarized from the following aspects of stomata movement,osmolytes,antioxidant system,methylglyoxal detoxification system,and heat shock proteins(HSPs);moreover,the future research direction is presented. This review further expanded the possible physiological functions of H2S signal and the formation mechanism of drought tolerance,which is of significance to deeply understand the relationship between H2S and stress tolerance including drought tolerance in plants.
