RTE1 is required for the rescue of ctr1-1 growth by etr1^1-349. A and B, Phenotype (A) and hypocotyl length (B) of etiolated ctr1-1 seedlings with or without the etr1^1-349 and 35S:RTE1 transgenes. C and D, Phenotype of light-grown ctr1-1 seedlings (C) and adult plants (D) with or without the etr1^1-349 and 35S:RTE1 transgenes. E and F, Phenotype (E) and seedling hypocotyl length (F) of ctr1-1, ctr1-1 rte1-2, and mutants with the etr1^1-349 transgene. G and H, Phenotype of light-grown seedlings (G) and rosettes (H) of ctr1-1, ctr1-1 rte1-2, and mutants with the etr1^1-349 transgene. I to K, Relative expression of ERF1 (I), CHIB (J), and PDF1.2 (K) in ctr1-1 with or without etr1^1-349 and 35S:RTE1 transgenes. L, Relative expression of the etr1^1-349 transgene in etr1^1-349 ctr1-1 and RTE1ox etr1^1-349 ctr1-1. L10, The etr1^1-349 transgene was from the transformation line etr1^1-349ctr1-1 L10 by genetic cross. Data are means ± sd. ** P < 0.01 by Student’s t test (B) and Fisher’s lsd (G–I).
