| Type: | Family | Name: | AUX/IAA protein |
| Description: | The Aux/IAA family of genes are key regulators of auxin-modified gene expression []. The plant hormone auxin (indole-3-acetic acid, IAA) regulates diverse cellular and developmental responses in plants, including cell division, expansion, differentiation and patterning of embryo responses []. Auxin can regulate the gene expression of several families, including GH3 and SAUR, as well as Aux/IAA itself. The Aux/IAA proteins act as repressors of auxin-induced gene expression, possibly through modulating the activity of DNA-binding auxin response factors (ARFs) (). Aux/IAA and ARF are thought to interact through C-terminal protein-protein interaction domains found in both Aux/IAA and ARF.Recent evidence suggests that Aux/IAA proteins can also mediate light responses []. Some members of the AUX/IAA family are longer and contain an N-terminal DNA binding domain [] and may have an early function in the establishment of vascular and body patterns in embryonic and post-embryonic development in some plants. | Short Name: | AUX_IAA |
