Metabolic changes in the primary metabolism in shoots and roots in response to drought. Variation in metabolite levels in shoots and roots are presented as a log₂ ratio per variety, pairwise by stress versus control conditions. Bold values indicate significant differences between drought and well-watered conditions (Student t-test with Bonferroni correction, P < 0,05). Colour coding indicates significantly different metabolites with a log2FC higher or lower than one (two-fold in linear scale)
