Anthocyanin biosynthetic patterns in RVE-overexpression. (a) Phenotypes of ‘Zaosu’ fruitlet skins transiently overexpressing PbRVE1a, 1b, 7 and 8. (b) The overexpression levels of PbRVE1a, 1b, 7 and 8 in ‘Zaosu’ fruitlet skins. (c) The anthocyanin contents and the expression patterns of ALBGs in ‘Zaosu’ fruitlet skins which overexpressing PbRVEs. The number means the ratio of anthocyanin content in ‘Zaosu’ fruitlets skin overexpressing PbRVEs compared with the empty vector. OE: overexpression. The significant differences are based on comparisons with the empty vector. Error bars indicate the SEs of the means (n = 3). Data in (c) were analyzed using Student’s t-test: * p < 0.05, ** p < 0.01.
