Phenotypes, anthocyanin contents and expression levels of PbCOP1 genes at different leaf developmental stages. (A) Leaf phenotypes. (B) Anthocyanin contents in leaves. (C) PbCOP1 expression levels in leaves. R, red; HR, half red; G, green. ZS, ‘Zaosu’; RZS, ‘Red Zaosu’. All data are presented as the means ± standard errors of three biological replicates, and different letters above the columns indicate significant differences at P < 0.05 (Duncan’s range test).
