AtPRX71 negatively affects leaf epidermal cell size. Rosette leaves from 3-week-old wild-type (WT; A), atprx71-1 (B), and atprx71-2 (C) plants and two lines overexpressing AtPRX71 (35S:AtPRX71 lines 22 [D] and 24 [E]) were cleared and stained with ruthenium red, and images of the epidermis were taken with a microscope. Bars = 100 µm. F, Bars represent the average area of epidermal cells ± se (n > 20). Asterisks indicate significant differences between the wild type and mutants or transgenic plants according to Student’s t test. 71-1, atprx71-2; 71-2, atprx71-2. *, P < 0.05; ***, P < 0.01.
