Abstract

Auxin induces various distinct developmental responses, partly by regulating gene expression. The Aux/IAA genes are a large gene family, many of which are induced by auxin. Work on Arabidopsis Aux/IAA genes has begun to reveal that they can regulate development and auxin-induced gene expression. Furthermore, auxin responses require Aux/IAA protein turnover. Finally, recent evidence suggests that Aux/IAA proteins can mediate light responses. Work in the near future should test whether Aux/IAA proteins are antennae that connect auxin and light signals to endogenous developmental responses.
