Loss of AtPRX71 increases growth. A to C, Representative picture (A), fresh weight (B), and dry weight (C) of 4-week-old soil-grown wild-type (WT), atprx71-1, and atprx71-2 rosettes. Bar =1.5 cm. D, Fresh weight of 10-d-old wild-type, atprx71-1, and atprx71-2 seedlings grown in vitro on solid medium in the light. E, Hypocotyl length of 5-d-old wild-type, atprx71-1, and atprx71-2 etiolated seedlings grown in vitro on solid medium. B to E, Bars represent average weight ± se (n > 10 in each experiment); asterisks indicate statistically significant differences between the wild type and mutants according to Student’s t test. *, P < 0.05; ***, P < 0.01.
