Primary metabolism pathways of metabolites measured in detached leaves of Arabidopsis under light or dark conditions compared between Col-0 (wild-type) and the prodh1 prodh2 double-mutant. Heat-maps are shown for changes in metabolites in pooled samples of leaves 7–9 from the base of the plant after 5 d under light (left square) or dark (right square) conditions: the blue-to-yellow scale shows the log₂ ratio of the fold-change between the double-mutant and the wild-type. Data represents the mean values of four biological replicates for each time-point.
