乙烯是一种气态植物激素，最有可能在绿藻的进化过程中成为一种功能激素，在陆地定居之前。从这个古老的起源，乙烯演变成一个重要的生长调节剂，是必不可少的无数植物的发育过程。在营养生长中，乙烯似乎有双重作用，刺激和抑制生长，这取决于物种、组织和细胞类型、发育阶段、激素状态和环境条件。此外，乙烯信号和反应是内部和外部信号串扰的复杂网络的一部分。乙烯除了是控制根和芽生长的关键因素外，还可以促进开花、果实成熟和脱落，以及叶片和花瓣的衰老和脱落，因此，乙烯几乎在植物生命的每个阶段都起作用。最后但并非最不重要的是，与茉莉酸、水杨酸和脱落酸一起，乙烯在控制应激反应中很重要。
Ethylene is a gaseous plant hormone that most likely became a functional hormone during the evolution of charophyte green algae, prior to land colonization. From this ancient origin, ethylene evolved into an important growth regulator that is essential for myriad plant developmental processes. In vegetative growth, ethylene appears to have a dual role, stimulating and inhibiting growth, depending on the species, tissue, and cell type, developmental stage, hormonal status, and environmental conditions. Moreover, ethylene signaling and response are part of an intricate network in cross talk with internal and external cues. Besides being a crucial factor in the growth control of roots and shoots, ethylene can promote flowering, fruit ripening and abscission, as well as leaf and petal senescence and abscission and, hence, plays a role in virtually every phase of plant life. Last but not least, together with jasmonates, salicylate, and abscisic acid, ethylene is important in steering stress responses.
