The full-length cDNAs of rice and wheat S-adenosylmethionine decarboxylase gene were isolated and characterized. The rice SAMDC cDNA is 1560 bp in length, encoding a polypeptide of 398 amino acids, and the wheat SAMDC cDNA is 1351 bp in length, encoding a polypeptide of 392 amino acids. Both the rice and wheat SAMDC proteins contain the conserved proenzyme cleavage site and the PEST domains, which are commonly found in the SAMDC protein sequences of all eukaryotes.
