摘要：

We isolated an Arabidopsis knockout line lacking glutamate decarboxylase 1 (GAD1), one that produced gamma-aminobutyrate (GABA), as an oxidative stress-insensitive mutant, and found that chloroplastic H2O2 enhances GAD1 expression and GABA levels. This suggests a possible relationship between GABA metabolism and the chloroplastic H2O2-mediated stress response.
