Loss of AtPRX71 partially restores qua2-1 growth defects. A, Representative picture of wild-type (WT), atprx71-1, qua2-1, and atprx71-1 qua2-1 3-week-old soil-grown rosettes. Bar = 1 cm. B, Rosette fresh weight of wild-type, atprx71-1, qua2-1, and atprx71-1 qua2-1 4-week-old soil-grown plants. Bars indicate average weight ± se (n > 10). C, Hypocotyl length of 5-d-old wild-type, atprx71-1, and atprx71-2 etiolated seedlings grown in vitro on solid medium (n > 10). Different letters in B and C indicate significant differences according to one-way ANOVA followed by Tukey’s significance test (P < 0.05).
