Figure 7From: Perception of soft mechanical stress in Arabidopsis leaves activates disease resistanceThe effect of humidity on resistance of A. thaliana Col0 to B. cinerea and ROS accumulation after SMS. Leaves were stimulated by SMS and maintained for 1.5 h under high humidity in tightly covered well-watered trays (humid) or left in uncovered trays (dry) at room conditions prior to inoculation with B. cinerea and ROS detection. (A) Resistance to B. cinerea (n = 64; ±SE). One representative picture of the growth of B. cinerea was placed above each histogram as a visual illustration (trypan blue staining was carried out 3 days after inoculation). (B) Quantification of ROS production; three representative images of the fluorescent leaf surface were placed above each histogram as a visual illustration (n = 16; ±SD). Asterisks indicate statistically significant differences between treated samples and non-treated samples in humid and dry conditions, T-Test (p < 0,01).Back to article page
