IAA17/AXR3: biochemical insight into an auxin mutant phenotype.

The Plant cell - 1 Apr 2001

Ouellet F, Overvoorde P J, Theologis A

Abstract excerpt

The Aux/IAA genes are rapidly and specifically induced by the plant hormone auxin. The proteins encoded by this gene family are short-lived nuclear proteins that are capable of homodimerizing and heterodimerizing. Molecular, biochemical, and genetic data suggest that these proteins are involved in auxin signaling. The pleiotropic morphological phenotype and altered auxin responses of the semidominant axr3-1...
