an- t1 seedlings cope better with drought stress and pathogen attack than the wild type. (A-C) Phenotypic characterization of wild type and an-t1 under pathogen attack. Pathogenic lesions on wild type (A) and an-t1 (B) leaves are depicted. (C) Quantitative data of pathogenic assay is represented. (D-I) Phenotypic characterization of wild type and an-t1 under well watered (D), dehydrated (E) and re-hydrated (F) conditions. The H2O2 accumulations under well watered (G), dehydrated (H) and re-hydrated (I) are represented. After drought stress (E), the an-t1 was able to regain physiological functions upon re-hydration and resume normal growth, unlike wild type that withered away (F). H2O2 content is estimated in U/g FW, where U represents μmol, and FW represents fresh weight. Asterisks indicate significant differences between the mutant and the wild type. *P <0.001, **P <0.05, Student’s t test.
