Fig. 2From: The effect of promoter methylation on MdMYB1 expression determines the level of anthocyanin accumulation in skins of two non-red apple cultivarsRelative expression levels of genes related to anthocyanin biosynthesis in ‘Granny Smith’ and ‘Golden Delicious’ skins after bag removal. a: Expression of structural genes in the two cultivars after bag removal; b: Expression of regulatory genes in the two cultivars after bag removal. Data represent means ± standard deviation of four replicate samples. Different lower case letters indicate significant differences by Tukey’s multiple range test (p < 0.05)Back to article page
