Os01g0178500
The rice Os01g0178500 was reported as OsIAA1 in 2009 [1] by researchers from China.

Annotated Information
Function
- Aux/IAA and auxin response factor (ARF) are two important families that have been well recognized for their roles in auxin-mediated responses.
- OsIAA1 may play important roles in the cross-talk of auxin and brassinosteroid signaling pathways and plant morphogenesis.
Expression
- The results indicated that OsIAA1 was constitutively expressed in all the tissues and organs investigated.
- The expression of this gene was induced by various phytohormones including IAA, 2,4-D, kinetin, 24-epibrassinolide, and jasmonic acid.
Phenotypic analysis
- Over-expression of OsIAA1 in rice resulted in reduced inhibition of root elongation to auxin treatment, but increased sensitivity to 24-epiBL treatment. In addition, the OsIAA1-overexpression transgenic plants showed distinctive morphological changes such as decreased plant height and loose plant architecture.
