Comparison of secondary metabolite contents and transcript levels of flavonoid biosynthesis–related genes in small- and large-leaf varieties. (a) Contents of total phenol, flavonoids, and anthocyanins in the young and old leaf tissues of different tea varieties. (b) Transcript levels of CsCHS, CsANS, and CsANR in the young leaf tissues of different tea varieties. Transcripts levels were measured using qRT-PCR and normalized to that of 18S rRNA. (c) The flavonoid biosynthesis pathway in tea. Values are presented as the mean ± SD of three biologically independent experiments. Different letters indicate significant differences between varieties assessed using the LSD post-hoc test (p < 0.05). ANS anthocyanidin synthase; ANR anthocyanidin reductase; CHS chalcone synthase; DW dry weight; FW fresh weight; GAE gallic acid equilibrium.
