DESCRIPTION

Also known as GH38_ORYSI, GH3.8, GH3-8. Catalyzes the synthesis of indole-3-acetic acid (IAA)-amino acid conjugates, providing a mechanism for the plant to cope with the presence of excessive free auxin (PubMed:18192436). Produces more IAA-Asp levels than IAA-Ala levels in vitro (PubMed:18192436). May participate in the activation of disease resistance by preventing the accumulation of free IAA, which reduces the expression of a group of auxin-responsive genes encoding expansins that control cell wall loosening and expansion (PubMed:18192436). Contributes to late events in stamen and carpel differentiation, and influences floret fertility (PubMed:22016342).
