Prunus mume is the only plant in genus of Rosaceae family with a characteristic floral scent, and main component this scent benzyl acetate. By contrast, acetate not synthesized persica flowers. Here, we searched for alcohol acetyltransferase (BEAT) genes based on genomic data from P. found 44 unique PmBEATs mume. These genes, which were mainly detected clusters chromosomes, originated gene duplication events during species evolution mume, retroduplication tandem two dominant patterns. The PmBEAT34, PmBEAT36 PmBEAT37, generated by duplication, highly expressed flowers, their highest levels blooming stage. In vitro, PmBEAT3, PmBEAT37 all had activity that was localized cytoplasm. Overexpression or increased production petal protoplasts interference expression these slightly decreased content. addition, light temperature regulated genes. According to results, hypothesize expansion PmBEAT genome induce
