Relative expression level and FPKM (Fragments Per Kilobase of transcript per Million mapped reads) of candidate structural genes involved in anthocyanin biosynthesis, chlorophyll metabolism, and carotenoid biosynthesis in three different colored leaves. C1, C2, and C3 stands for variegated pink–green leaves, light pink leaves, and pink leaves respectively. C3 was used as reference to calculate the relative expression of genes. Error bar represents ±SE of the means of three duplications. Asterisks represent significant differences by T–test (*p < 0.05, ** p < 0.01)
