Abstract: Polyamine plays important roles in plant growth and the response to biotic and abiotic stress. S-adenosylmethionine decarboxylase (SAMDC) is a key enzyme involved in the biosynthesis of the polyamines. The substrate for the SAMDC is S-adenosylmethionine (SAM) and the product is decarboxylated SAM which provides the aminopropyl groups for subsequent synthesis of spermidine and spermine. This article reviews the progress on classification， evolution， structure character and biological function of SAMDC genes in plants.
