Fig. 6From: 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 skins of ‘Granny Smith’ and ‘Golden Delicious’ fruits after 5-aza-2'-deoxycytidine (5-aza-2’-dC) treatment. a: Structural gene expression in the two cultivars; b: Regulatory gene expression in the two cultivars. 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
