FERONIA-mediated TIR1/AFB2 oxidation stimulates auxin signalling in Arabidopsis.
Molecular PlantThe phytohormone auxin plays a pivotal role in governing plant growth and development. While the TRANSPORT INHIBITOR RESPONSE1/AUXIN SIGNALING F-BOX (TIR1/AFBs) receptors function in both the nucleus and cytoplasm, the mechanism governing the ...

Adenylate cyclase activity of TIR1/AFB auxin receptors in plants
Nature, 2022The phytohormone auxin is the major coordinative signal in plant development1, mediating transcriptional reprogramming by a well-established canonical signalling pathway. TRANSPORT INHIBITOR RESPONSE 1 (TIR1)/AUXIN-SIGNALING F-BOX (AFB) auxin receptors are F-box subunits of ubiquitin ligase complexes.

The F-box protein TIR1 is an auxin receptor
Nature, 2005The plant hormone auxin regulates diverse aspects of plant growth and development. Recent studies indicate that auxin acts by promoting the degradation of the Aux/IAA transcriptional repressors through the action of the ubiquitin protein ligase SCF(TIR1). The nature of the signalling cascade that leads to this effect is not known.

Mechanism of auxin perception by the TIR1 ubiquitin ligase
Nature, 2007 Auxin is a pivotal plant hormone that controls many aspects of plant growth and development. Perceived by a small family of F-box proteins including transport inhibitor response 1 (TIR1), auxin regulates gene expression by promoting SCF ubiquitin-ligase-catalysed degradation of the Aux/IAA transcription repressors, but how the TIR1 F-box protein senses

The Arabidopsis F-box protein TIR1 is an auxin receptor
Nature, 2005Despite 100 years of evidence showing a pivotal role for indole-3-acetic acid (IAA or auxin) in plant development, the mechanism of auxin perception has remained elusive. Central to auxin response are changes in gene expression, brought about by auxin-induced interaction between the Aux/IAA transcriptional repressor proteins and the ubiquitin-ligase ...

Cloning and functional characterization of auxin receptor TIR1 in Gossypium hirsutum
Acta Physiologiae Plantarum, 2021Transport inhibitor response 1 (TIR1), as an F-box family protein, is a nucleus receptor of auxin in plants. It is essential in the auxin signal transduction pathway and the expression of auxin-responsive genes. As the most important hormone in plants, auxin has a great influence on the ovule and fiber development of cotton (Gossypium hirsutum L ...
