Phenotypes of wild-type and transformed seedlings expressing 35S:IAA3mImII-1, 35S:IAA6mImII-1, 35S:IAA19mImII-1, IAA19:IAA19mImII-1, and IAA19:VP16-IAA19mImII-1 transgenes. A, Photographs of 7-d-old seedlings. Two representative seedlings are shown for the wild type (Wt) and each IAA transformant. B, Histochemical GUS staining of 7-d-old wild-type and transformed seedlings. Seedlings were stained for 15 h at 37°C. C, Hypocotyl length for 7-d-old wild-type and transformed seedlings. Error bars indicate sd (n ≥ 15, ANOVA test, P < 0.05). D, Primary root length for 7-d-old wild-type and transformed seedlings. Error bars indicate sd (n ≥ 15, ANOVA test, P < 0.05). Lanes are as follows: a, the wild type; b, 35S:IAA3mImII-1; c, 35S:IAA6mImII-1; d, 35S:IAA19mImII-1; e, IAA19:IAA19mImII-1; f, IAA19:VP16-IAA19mImII-1.
