Expression of Anthocyanin Regulators in 35Spro:Lc Petunias.
(A) Anthocyanin pigmentation phenotypes of wild-type MP or plants expressing the maize bHLH anthocyanin regulator Lc from a CaMV35S promoter, grown under shade (50 to 350 µmol m−2 s−1) or high-light (750 µmol m−2 s−1) conditions.
(B) Transcript abundance for the Lc transgene or endogenous anthocyanin regulators in MP or Lc petunias. Means ± se are shown (n = 4 biological replicates); statistical significance was determined by one-way ANOVA (P < 0.001); significant differences between means (LSD, P = 0.05) are indicated where letters (a, b, c, and d) above the bar differ.
