Arabidopsis IAR4 modulates auxin response by regulating auxin homeostasis.

Plant physiology - 1 Jun 2009

Quint Marcel, Barkawi Lana S, Fan Kai-Ting, Cohen Jerry D, Gray William M

Abstract excerpt

In a screen for enhancers of tir1-1 auxin resistance, we identified two novel alleles of the putative mitochondrial pyruvate dehydrogenase E1alpha-subunit, IAA-Alanine Resistant4 (IAR4). In addition to enhancing the auxin response defects of tir1-1, iar4 single mutants exhibit numerous auxin-related phenotypes including auxin-resistant root growth and reduced lateral root development, as well as defects in...
