Plant hormone indole-3-acetic acid (IAA) has various physiological function, but IAA biosynthetic and signal pathway is still unclear. Also the components mediating the crosstalk between IAA and other plant hormones are little known. As IAA is essential for plant growth, the analysis of IAA biosynthesis knock-out mutants in the main pathway and the selection of double mutant with the knock-out mutant background may have been difficult. There are several pathways in IAA biosynthesis and some of them may function complementarily to each other. Mutants that have defect in such pathway may show no significant phenotype to distinguish mutants from wild type. On the other hand, the use of IAA specific biosynthesis inhibitor may bypass these difficulties and would make it possible to isolate new mutants. We can raise the next point as an overall merit of using IAA biosynthesis inhibitor for isolating IAA mutants. That is, we could isolate double or triple mutant-like mutants by screening mutants with the inhibitor.
