Fig. 13From: Gamma-aminobutyric acid (GABA) alleviates salt damage in tomato by modulating Na+ uptake, the GAD gene, amino acid synthesis and reactive oxygen species metabolismContent of H2O2 and tissue staining results in leaves of tomato seedlings under NaCl stress with or without GABA. a: H2O2 content. b: Analysis of ROS production by DAB stainingNote: Each value is the mean ± SD of three independent experiments. Different lower-case letters in each column shape indicate significant difference at P < 0.05 by Duncan’s testBack to article page
