H2O2 accumulation and callose deposition in the leaves treated with γ-PGA hydrolysates. a H2O2 accumulation in the leaves of wild-type line of Arabidopsis pre-treated with γ-PGA hydrolysates following with infection by Pst DC3000. b Callose deposition in the leaves of wild-type line of Arabidopsis pre-treated with γ-PGA hydrolysates following with infection by Pst DC3000. c H2O2 accumulation in the leaves of mutant lines of Arabidopsis pre-treated with γ-PGA hydrolysates following with infection by Pst DC3000. d Callose deposition in the leaves of mutant lines of Arabidopsis pre-treated with γ-PGA hydrolysates following with infection by Pst DC3000. e Pathogen amounts recovered from the leaves of mutant lines of Arabidopsis pre-treated with γ-PGA hydrolysates following with infection by Pst DC3000. *indicates significant difference from the control (CK, pre-treated with water). γ-PGA: the γ-PGA hydrolysates
