FIGURE 3.
Metabolic analysis of phenolic compounds and expression analysis of related biosynthetic genes in different parts of tea flowers. (A) Phenotypes of different parts of the flower. (B) Metabolic analysis of the main phenolic compounds in different parts of tea flowers. The petal/anther data were relative peak area comparisons of the petal to the anther. The peak area data of anthers, filaments, pistils, and calyxes were processed and fell into the interval [0, 1] according to the ratio. FGs*, Flavone glycosides. (C) Expression analysis of genes in the shikimate, phenylpropanoid, and flavonoid pathways in different parts of the tea flower. The value represents the FPKM value.
