Genetic characterization of mutants resistant to the antiauxin ${it p}$-chlorophenoxyisobutyric acid reveals that ${it AAR3}$, a gene encoding a DCN1-like protein, regulates responses to the synthetic auxin 2,4-dichlorophenoxyacetic acid in Arabidopsis roots

We screened mutants for root growth resistance to a putative antiauxin, PCIB, which inhibits auxin action by interfering the upstream auxin signaling events. Eleven PCIB-resistant mutants were obtained. Genetic mapping indicates that the mutations are located in at least 5 independent loci including two known auxin-related loci, ${it TIR1}$ and ${it AtCUL1}$. ${it antiauxin-resistant}$ mutants (${it aar}$s) ${it aar3-1}$, ${it aar4}$ and ${it aar5}$ were also resistant to 2,4-D as shown by a root growth assay. Positional cloning of ${it aar3-1}$ revealed that the ${it AAR3}$ gene encodes a protein with a domain of unknown function (DUF298), which has not previously been implicated in auxin signaling. The protein has a putative nuclear localization signal and shares homology with the DCN-1 protein through the DUF298 domain. The results also indicate that PCIB can facilitate the identification of factors involved in auxin or auxin-related signaling.

A Small acidic protein 1 (SMAP1) mediates responses of the arabidopsis root to the synthetic auxin 2,4-dichlorophenoxyacetic acid

2,4-D, a chemical analogue of IAA, is widely used as a growth regulator and exogenous source of auxin. It is believed that they share a common response pathway. Here, we show that a mutant, ${it antiauxin resistant1}$ (${it aar1}$) is resistant to 2,4-D, yet nevertheless responds like the wild type to IAA. That the ${it aar1}$ mutation alters 2,4-D responsiveness specifically was confirmed by analysis of GUS expression in the${it DR5:GUS}$ and ${it HS:AXR3NT-GUS}$ backgrounds, as well as by real-time PCR quantification of ${it IAA11}$ expression. Complementation and RNAi experiments identified a gene that confers 2,4-D responsiveness. The gene encodes a ${it small, acidic protein 1}$with unknown function and present in plants, animals, and invertebrates. These results suggest that SMAP1 is a regulatory component that mediates responses to 2,4-D and that responsiveness to 2,4-D and IAA are partially distinct.

PCIB (${it p}$-chlorophenoxyisobutyric acid) is known as a putative antiauxin and is widely used to inhibit auxin action, although the mechanism of PCIB-mediated inhibition of auxin action is not characterized very well at molecular level. In the present work, we showed that PCIB inhibited BA::GUS expression induced by IAA, 2,4-D and NAA. PCIB also inhibited auxin dependent DR5::GUS expression. RNA hybridization and quantitative RT-PCR analyses suggested that PCIB reduced auxin-induced accumulation of transcripts of ${it Aux/IAA}$ genes. In addition, PCIB relieved the reduction of GUS activity in ${it HS::AXR3NT-GUS}$ transgenic line in which auxin inhibits GUS activity by promoting degradation of the AXR3NT-GUS fusion protein. Physiological analysis revealed that PCIB inhibited lateral root production, gravitropic response of roots and growth of primary roots. These results suggest that PCIB impairs auxin signaling pathway by regulating Aux/IAA protein stability, and thereby affects the auxin-regulated Arabidopsis root physiology.
