Figure 5. Flavonoid content (relative peak area) in mutant lines changed in flavonoid metabolism under non-acclimated (NA) and 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 or six (only Col-0 wild type and single mutants) biological replicates with higher flavonoid content in mutant lines in comparison to corresponding wild type in red and lower content in blue, as indicated by the scale bar. Central flavonols and anthocyanins are framed in green and purple, minor flavonoids and flavonols with unknown structure in black (see also Suppl. Table 2).
