【摘要】 气体信号分子是广泛存在于植物体内的一种重要的信号物质,在植物生长发育过程中承担着重要作用,并且对植物的抗逆性有较为明显的缓解作用。从一氧化碳、一氧化氮、硫化氢3种主要气体信号分子的来源出发,介绍了气体信号分子在植物抗旱性方面的研究成果,综述了气体信号分子诱导植物产生抗旱性的机理,分析了其在植物抵御干旱胁迫中的作用,并对气体信号分子在植物抗旱性的应用进行了展望。更多还原

【Abstract】 Gas signaling molecule is an important signaling material widely existed in plants. It plays important role in plant growth and development and has significant effect on alleviating plant stress resistance. Starting from the origin of 3 major gas signaling molecules: carbon monoxide,nitric oxide and hydrogen sulfide,this paper introduced the research results of gas signal molecules in plant drought resistance; reviewed the mechanism of plant drought resistance induced by gas signal molecules; analyzed the effects of plant in resisting drought stress; and prospected the application of gas signal molecules in plant drought resistance.更多还原
