Arabidopsis SHY2/IAA3 inhibits auxin-regulated gene expression.

The Plant cell - 1 Feb 2002

Tian Qing, Uhlir Nicholas J, Reed Jason W

Abstract excerpt

In Arabidopsis, SHY2 encodes IAA3, a member of the auxin-induced Aux/IAA family. Gain-of-function mutations in SHY2/IAA3 cause enlarged cotyledons, short hypocotyls, and altered auxin-regulated root development. Here we show that the gain-of-function mutation shy2-2 decreases both the induction and repression of auxin-regulated genes, suggesting that SHY2/IAA3 acts as a negative regulator in auxin signaling....
