Fig. 2From: Unraveling the expression of differentially expressed proteins and enzymatic activity in response to Phytophthora nicotianae across different flue-cured tobacco cultivarsActivities of defense-related enzymes across different flue-cured tobacco cultivars in response to black shank pathogen. PPO activity (A), POD activity (B), SOD activity (C), and MDA contents (D). Error bars represent the standard error of means (± SEM, n = 3). Different small letters on error bars indicate a significant difference according to Duncan's multiple range test at p < 0.05Back to article page
