Interplay between ROS Production and ROS Scavenging Modulates the ROS Wave in Response to HS.

(A) Experimental design showing the application of HS to local leaves (blue or red arrows) and the subsequent sampling of systemic tissue (black arrows).

(B) Time-course protein blot analysis showing the accumulation of MBF1c in systemic tissue of wild-type, rbohD, and apx1 mutants in response to a local HS stimulus.

(C) Quantification of protein expression in (B) (n = 3). Error bars = sd. **Student’s t test significant at P < 0.01.
