BBX11 promotes accumulation of photo-protective metabolites. A, Heat map showing the relative accumulation of central and secondary metabolites and (B) relative accumulation of phenolic acids, in 18-day-old seedlings of the indicated genotypes grown in constant white light and exposed to 0, 24, and 96 h of supplemental UV-B 3 before harvesting. In (A) heat map scale (+3 to −3) indicates abundance of metabolite. Four biological replicates were taken for the analyses from each of the treatments. In (B) error bars represent sem, n = 4. Statistical groups indicated by letters were determined by one-way ANOVA, with Tukey’s test P ≤ 0.05.
