Figure 8. Different environmental conditions alter anthocyanin accumulation by changing the expression of anthocyanin related MBW-complex and biosynthetic genes.

(A) Leaves harvested from the different temperature conditions. (B) Leaves harvested in 1, 3, 5 day after 15 °C treatment plants. (C) The ‘Zijuan’ tea leaves harvested from different photoperiod conditions. (D) The genes expression profile after 15 °C treatment with 0, 10, 24, 48 h. (E) Low temperature (15 °C) increases the accumulation of anthocyanin in leaves. The 0, 1, 3, 5 day indicates anthocyanin levels after 15 °C treatment. (F) The genes expression profile under different photoperiod conditions. (G) The anthocyanin levels under different photoperiod conditions. Error bars on each symbol indicate the mean ± SD of three replicate reactions. Asterisks indicate significant difference (P < 0.01) between combinations by Student’s t-test.
