摘　　要：多胺是一类小分子生物活性物质,广泛存在于生物体内,与植物的生长发育、衰老及抗逆性都有着密切的联系。就多胺合成途径中的两个关键酶基因,即S-腺苷甲硫氨酸合成酶基因(SAMS)和S-腺苷甲硫氨酸脱羧酶基因(SAMDC)的克隆、表达,以及转S-腺苷甲硫氨酸合成酶基因(SAMS)和转S-腺苷甲硫氨酸脱羧酶基因(SAMDC)表达调控等方面的研究进行回顾总结,并对其应用前景进行展望。Polyamine is an important physiological regulation substance functioning in a wide variety of biological processes, such as plant growth, development, senescence and adversity stress tolerance, which widely exist in all living organisms. S-adenosylm ethionIne synthetase gene（SAMS）and S-adenosylmethionine decarboxylase gene（SAMDC）are the two key genes in the polyamine synthesis pathway. This paper summarized the gene cloning, expression and transgenic expression regulation of SAMS and SAMDC, and other aspects also reviewed. Its application prospect was discussed in the end.
