Complementation of rnt1-1: comparison of wild type (wt), rnt1-1, molecularly complemented rnt1-1 (mol compl), and three independent rnt1-1 lines functionally complemented by ectopic overexpression of CYP83A1 (2.8.6, 2.9.5, and 2.24.3). Seedlings were analyzed after 1 week and after 2 weeks (bar = 3 mm); mature plants were analyzed after 6 weeks (bar = 10 cm). Hypocotyl lengths of 1-week-old seedlings: wt, 2.6 ± 0.1 mm; rnt1-1, 3.6 ± 0.2 mm; mol compl, 2.1 ± 0.1 mm; 2.8.6, 1.7 ± 0.1 mm; 2.9.5, 1.8 ± 0.1 mm; and 2.24.3, 1.7 ± 0.1 mm. Hypocotyl lengths are given with their ses of mean (n = 20).
