Metabolite profiling of wild-type and Ljgln2-2 mutant plants. The metabolomic profiles of wild-type and Ljgln2-2 mutant plants were statistically analyzed using a supervised two-factorial ANOVA, with “genotype” and “time of exposure to normal CO₂” (0, 2, 3, 4, 6, 8, and 10 d after transfer from high to normal CO₂ atmosphere) as factors at a stringent threshold (P < 0.0001). Five different groups were defined by clustering tools. Data represent the direct normalized responses of metabolite pool measures. The color bar represents this relative unit (r.u.).
