Overexpression of the anthocyanin-specific transcription factor PAP1 fails to overcome the anthocyanin repression of fah1. A, Soil-grown pap1-D and fah1 pap1-D plants 3 weeks after planting. B, Representative chromatograms of dissected leaf blades (top) and midribs (bottom) of pap1-D and fah1 pap1-D plants. C, Quantification of total anthocyanin levels in the leaf sections shown in B together with wild-type and fah1 controls. Each bar shows the mean of three samples, with error bars indicating sd.
