摘　　要：ACC脱氨酶是一种抑制乙烯生物合成的胞内酶,目前在植物体内尚未发现该酶。其作用机理涉及植物体内乙烯生成的蛋氨酸循环途径,在植物的保鲜、寿命延长、以及对Cu、Fe、Zn、Co、Ni、Pb、Cd等重金属的吸附等方面起着重要的作用。就ACC脱氨酶的基因特征、在蛋氨酸循环途径中作用机理、以及转基因应用等方面进行了系统的阐述,并对今后进一步研究提出了适宜的建议。ACC-deaminasc is an endoenzyme that can be able to reduce biosynthesis of ethylene, and has not been discovered in plant body. Its function mechanism involves in methionine circulating path of biosynthesis of plant ethylene. Also, it plays important function in keeping plant fresh, life span extension and adsorbing heavy metals contain. In this paper, the gene characteristic of ACC- deaminase, function mechanism of methionine circulating path and transgenic application were systematical summarized, and feasible suggestions for further researches were presented.
