Log2 fold change of relative transcript abundance (2^−ΔCt) of flavonoid biosynthesis genes in mutant lines relative to Col-0 or Ler wild type under non-acclimated (NA) and cold acclimated (ACC) conditions.

Mutant lines in Col-0 (yellow framed) and Ler (orange framed) are sorted according to their positions in the flavonoid biosynthetic pathway. Data represent averages of three biological replicates per line and condition with higher relative expression in mutant lines compared to wild type in red and lower expression in blue, as indicated by the scale bar. Genes encoding TFs are framed in black, flavonol biosynthesis genes in green and anthocyanin biosynthesis genes in purple (see also Suppl. Table 1).
