GLS pattern in wild-type (Wt), leuc, ipmdh1 and leuc:ipmdh1 mutants. Aliphatic GLSs are grouped according to their chain length (C3–C8), and indole GLS were summed as one group. GLS concentrations are given in µmol/mg ± standard deviation of three independent replicates. Statistical significant differences (F-test, P < 0.05) are indicated by different letters. (A) Seeds. (B) Leaves.
