Abstract: 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.

Key words: polyamine, SAMS, SAMDC, gene clone, expression regulation
