Hao, Ruijie published the artcileIdentification and specific expression patterns in flower organs of ABCG genes related to floral scent from Prunus mume, SDS of cas: 140-11-4, the main research area is Prunus flower ABCG gene expression.
Prunus mume has a unique floral scent feature that can volatilize a large amount of benzyl acetate into the air during flowering. At present, the efficient volatilization mechanism of P. mume floral scent components is still unclear. The volatilization of the key aromatic components in P. mume Caizhi Wufen was explored in different parts of flowers. Our results showed that filaments are the key fragrance-releasing parts of benzyl acetate. Moreover, the volatilization rates of diverse aromatic components were different in several parts. We also identified 130 ABC genes from P. mume, which were divided into eight subfamilies. Among the ABC genes, 55 were PmABCGs, including 24 half-size mol. transporters (white-brown complex, WBC) located on the cell membrane. Combined with RNA sequencing (RNA-seq) anal., most of the ABCG subfamily genes were specifically expressed in flowers. Importantly, they were also WBC genes and expressed high in filaments. Correlation anal. of volatilization rate and the genes expression of PmABCG showed that the volatilization of benzaldehyde and benzyl alc. were highly correlated with PmABCG2, 18, 26, and that of benzyl acetate was highly correlated with PmABCG9, 13 and 23. Therefore, the current study would provide a valuable guide for elucidating the transmembrane transport mechanism of benzenoid volatiles and study further a biol. function of different fragrance-releasing parts of flowers.
