IAA Dose–Response for Primary Root Length in Arabidopsis Plants Transformed with Antisense Orientation of AtRanBP1c.
Data shown are means ±sd of primary roots (n ≥ 5). The arrow indicates the mean length of the primary root of wild-type plants (17.1 ± 2.7 mm). This length did not change significantly in wild-type plants treated with IAA concentrations ≤10−10 M. Mean root lengths of transgenic plants treated with 10−10 and 10−12 M IAA differed significantly from each other and from the lengths of plants not treated with IAA or treated with 10−14 IAA (P ≤ 0.05), but the lengths of roots not treated with IAA or treated with 10−14 M IAA did not differ significantly when significance was analyzed by Student's t test.
