title: Analysis of a putative auxin biosynthesis inhibitor, indole-3-oxoethylphosphonic acid, in Arabidopsis.
abstract: Previously we identified indole-3-acetic acid (IAA) biosynthesis inhibitors that act on the conversion of l-tryptophan to indole-3-pyruvic acid in the IAA biosynthesis of Arabidopsis. In the present study, we synthesized a new compound, indole-3-oxoethylphosphonic acid (IOEP), and found that IOEP had an inhibitory effect on IAA biosynthesis in Arabidopsis. The results suggest that IOEP is a novel inhibitor of auxin biosynthesis in Arabidopsis.
