Resistance to B. cinerea and ROS production in response to SMS in leaves of A. thaliana Col0 . (A) Effect of 10 SMS events on resistance of A. thaliana Col0 to B. cinerea (n = 48; ±SE). Four representative pictures of necrosis caused by B. cinerea were placed above each histogram as a visual illustration. (B) Quantification of ROS production in leaves of A. thaliana Col0 after 10 events of SMS (n = 12; ±SD). ROS were determined immediately after SMS. Three representative images of the fluorescent leaf surface were placed above each histogram as a visual illustration. (C) Dose–response of SMS-induced resistance to B. cinerea and ROS accumulation in leaves of A. thaliana Col0. Single or multiple SMS events were carried out on leaves prior to inoculation with B. cinerea (n = 48; ±SE). (D) Dose–response of SMS-induced ROS accumulation in leaves of A. thaliana Col0. Single or multiple SMS events were carried out on leaves prior to quantification of ROS production (n = 12; ±SD). One representative image of the fluorescent leaf surface was placed above each histogram as a visual illustration. For all experiments in this figure, plants were kept under humid conditions after treatment and each experiment was repeated 4 times with similar results. Asterisks indicate statistically significant differences between treated samples and non-treated samples, T-Test (p < 0,01).
