Auxin signaling through TIR1/AFB2/AFB3 mediates feedback regulation of indole-3-acetic acid biosynthesis.
Title: Auxin signaling through SCF

HSP90 stabilizes auxin receptor TIR1 and ensures plasticity of auxin responses
Title: HSP90 stabilizes auxin receptor TIR1 and ensures plasticity of auxin responses.

These results demonstrate that HSP90 masks a point mutation in the auxin receptor TIR1 and thereby buffers auxin-responsive phenotypes.
Title: HSP90 Stabilizes Auxin-Responsive Phenotypes by Masking a Mutation in the Auxin Receptor TIR1.

We propose oligomerization of TIR1 as a novel regulatory mechanism in the regulation of auxin-mediated plant patterning and development.
Title: Oligomerization of SCFTIR1 Is Essential for Aux/IAA Degradation and Auxin Signaling in Arabidopsis.

Results suggest the MIRNA393a and MIRNA393b -mediated regulation of TIR1 and AFB2 during embryogenic transition.
Title: miR393 contributes to the embryogenic transition induced in vitro in Arabidopsis via the modification of the tissue sensitivity to auxin treatment.
