The expression pattern of genes related to ethylene and polyamine biosynthesis were analyzed in octoploid strawberry fruits in different ripening phases. RNA was isolated from Fragaria x ananassa Duch cv. Asia and used to synthesize cDNA by reverse transcriptase enzyme, which was applied in qPCR with primers designed for S-adenosyl-L-methionine synthases (FaSAMS1-3), S-adenosyl-L-methionine decarboxylases (FaSAMDC1-3), arginine decarboxylase (FaADC), spermidine synthase (FaSPDS), 1-aminocyclopropane-1-carboxylate synthases (FaACS1-4) and 1-aminocyclopropane-1-carboxylate oxidase (FaACO1-4) gene sequences. Based on the comparison made between the expression patterns of ethylene- and polyamine-related genes and those of the common precursor- and pathway shift-related genes, it appeared that with the exception of FaSAMS2, FaSAMDC1 and FaSAMDC2, the genes involved in polyamine biosynthesis showed decreasing level of expression as ripening proceeded.
