FIGURE 2

Changes of gene expression involving chlorophyll biosynthesis (A) and carotenoid biosynthesis (B) in the leaves of purple-leaf, green-leaf, and yellow-leaf tea cultivars. Data were assessed by one-way ANOVA followed by Fisher’s LSD test. Values in the same row that are labeled with different letters (a–f) differ significantly (p < 0.05). The letters A and B after the tea cultivar name represent new leaves (one bud and two leaves) and old leaves, respectively. HEMA, glutamyl-tRNA reductase; HEML, glutamate 1-semialdehyde aminotransferase; HEME, uroporphyrinogen decarboxylase; HEMF, coproporphyrinogen oxidative decarboxylase; FECH, ferrochelatase; CHLH, Mg chelatase H subunit; POR, protochlorophyllide oxidoreductase; CAO, chlorophyllide a oxygenase; NOL, NYC1-like; PSY, phytoene synthase; PDS, phytoene desaturase; ZDS, ζ-carotene desaturase; ZEP, zeaxanthin epoxidase.
