摘　　要：乙烯是一种重要的植物激素,在植物生长和发育以及对外界环境信号的响应中发挥重要作用。乙烯调控了豆科植物的黄化苗的三重反应和光下幼苗的生长,能够促进叶片和花的衰老和脱落。豆科植物能与根瘤菌形成互利共生关系,在根部形成一种特异的固氮器官——根瘤。在结瘤过程中,由于豆科植物结瘤习性或遗传背景的不同,乙烯能够抑制或者促进根瘤的形成。乙烯与其它植物激素的互作也调控了豆科植物根瘤的形成。文章对乙烯信号途径调控豆科植物的生长发育和根瘤形成的相关研究做了综述和分析,并就未来关于豆科植物乙烯信号转导的研究进行了探讨和展望。As an important gaseous phytohonnone, ethylene plays important roles in plant growth, development and responses to external environmental cues. Ethylene regulates not only the triple response of etiolated seedlings, hut also the growth and development of seedlings under light, which includes the senescence and abscission of leaf and flower in legumes. Legumes can establish a symbiotic relationship with rhizobia, resulting in the formation of root nodules that can fix nitrogen. Ethylene can inhibit or stimulate the nodulation depending on the differences of nodule development or genotypes of legumes. The crosstalk between ethylene and other phytohormones also plays a regulator）, role in nodulation. This article reviewed the current advances in the ethylene regulation of growth, development and nodulation in legumes. The research prospect of ethylene signaling in legumes were also discussed.
