摘　　要：乙烯具有复杂的生物学功能,它调节着植物生长发育和许多的生理生化过程。乙烯也被认为是一种胁迫应答激素,直到近几年关于乙烯生物合成及信号转导途径与植物盐胁迫的关系才逐渐被挖掘出来。乙烯在不同水平、层次参与盐胁迫反应,包括乙烯合成关键酶(ACS)和乙烯受体,细胞质中CTR1和EIN2以及细胞核中EIN3传导、响应盐信号。但是乙烯合成和信号转导途径在植物盐胁迫响应过程中仍然存在许多未解决的问题。主要介绍乙烯合成及信号转导途径的各组分与盐胁迫关系的最新研究进展,并讨论其存在的主要问题。Ethylene has complex biological functions,it is well known for its participation in modulating growth dynamics,developmental events and the physiological and biochemical processes.Ethylene also has been regarded as a stress hormone,but only recently the links among ethylene biosynthesis,ethylene signaling pathway and salt stress are slowly uncovered.Ethylene biosynthesis and ethylene signaling modulate salt response at different levels,including the key enzyme of ethylene biosynthesis（ACS）,membrane receptors,CTR1 and EIN2 in cytoplasm,and EIN3 in nucleus perceive and respond to the salt signal.However,the roles of ethylene biosynthesis and the ethylene signaling pathway in salt stress responses remain an open question.In this paper,we summarized the related evidences for the relationships among ethylene biosynthesis,the whole ethylene signaling pathway and plant salt stress.Then,we discussed some remaining problems.
