Abstract excerpt
The plant hormone auxin can be regulated by formation and hydrolysis of amide-linked indole-3-acetic acid (IAA) conjugates. Here, we report the characterization of the dominant Arabidopsis iaa-leucine resistant3 (ilr3-1) mutant, which has reduced sensitivity to IAA-Leu and IAA-Phe, while retaining wild-type responses to free IAA. The gene defective in ilr3-1 encodes a basic helix-loop-helix leucine zipper...
