Metabolite levels in WT and mutant plants.

The levels of different metabolites were determined from leaves of WT and Ljgln2-2 mutant plants grown in high CO₂ conditions (0 days) and after different periods of time under normal CO₂ conditions. Metabolite levels are expressed as relative units with the exception of NH₄⁺ and CP that are expressed in μmol·g FW^-1. Numbers in bold represent significant differences between WT and mutant genotypes at this time point according to Student’s t test (p<0.05).

*CP levels have two decimal digits since they were measured using a different technique compared to the other metabolites.
