Metabolite profiling of soluble sugars (including sorbitol, a sugar alcohol) for Arabidopsis Col-0 wild-type and nia1nia2 mutant upon 2.5 mM 3BN treatment for 24 h. For sucrose, One-way ANOVA and Tukey post hoc test were used with different letters denoting a significant difference (P < 0.05). For glucose, fructose and sorbitol, where the homogeneity of variance assumption could not be fulfilled, Welch one-way test and pairwise t-test were used with different letters denoting a significant difference (P < 0.05).
