Changes in metabolite levels in the basal portions of the gs1;2 mutant shoots. Seedlings were grown hydroponically in the presence of 1 mM NH4Cl until the fourth leaf stage. Metabolites that significantly increased in the basal portions of the gs1;2 mutant shoots relative to those of the wild type are in red boxes, while metabolites that decreased in the basal portions of the gs1;2 mutant shoots relative to those of the wild type are in blue boxes (P < 0.05 by Student’s t-test). Open boxes indicate no significant difference between the wild type and gs1;2 mutants regarding metabolite levels. Compounds with gray letters could not detect by using GC-TOF-MS.
