Transcription of TIR1-controlled Genes Can be Regulated within 10 Minutes by an Auxin-induced Process. Can TIR1 be the Receptor? [PDF]
Frontiers in Plant Science, 2016 ABP1 and TIR1/AFBs are known as auxin receptors. ABP1 is linked to auxin responses several of which are faster than ten minutes. TIR1 regulates auxin-induced transcription of early auxin genes also within minutes.

Arabidopsis thaliana in vitro shoot regeneration is impaired by silencing of TIR1
Biologia Plantarum, 2012 Arabidopsis shoots regenerate from root explants through a two-step process consisting of pre-incubation on an auxin-rich callus induction medium (CIM), followed by transfer to a cytokinin-rich shoot induction medium (SIM).

TIR1-produced cAMP as a second messenger in transcriptional auxin signalling [PDF]
NatureAbstract The phytohormone auxin (Aux) is a principal endogenous developmental signal in plants. It mediates transcriptional reprogramming by a well-established canonical signalling mechanism. TIR1/AFB auxin receptors are F-box subunits of an ubiquitin ligase complex; after auxin perception, they associate with Aux/IAA transcriptional ...

Distinct functions of TIR1 and AFB1 receptors in auxin signalling
Molecular Plant, 2023 Abstract Auxin is the major plant hormone regulating growth and development (Friml, 2022). Forward genetic approaches in the model plant Arabidopsis thaliana have identified major components of auxin signalling and established the canonical mechanism mediating transcriptional and ...

Complex regulation of the TIR1/AFB family of auxin receptors [PDF]
Proceedings of the National Academy of Sciences, 2009 Auxin regulates most aspects of plant growth and development. The hormone is perceived by the TIR1/AFB family of F-box proteins acting in concert with the Aux/IAA transcriptional repressors. Arabidopsis plants that lack members of the TIR1/AFB family are auxin resistant and display a variety of growth defects ...

eLife, 2020 The TIR1/AFB auxin co-receptors mediate diverse responses to the plant hormone auxin. The Arabidopsis genome encodes six TIR1/AFB proteins representing three of the four clades that were established prior to angiosperm radiation. To determine the role of

Model of the TIR1 Pathway for Auxin-Mediated Gene Expression [PDF]
Science's STKE, 2006 Auxin mediates numerous plant responses, some of which have been shown to require transcriptional regulation. One auxin response pathway, which depends on the relief of transcriptional repression, is mediated by TIR1 (transport inhibitor response protein 1). TIR1 is an auxin receptor and also a subunit of an SCF-type ubiquitin ligase.

AgronomyTIR1/AFB proteins are a class of auxin receptors with key roles in plant development and biotic and abiotic stress responses; several have been identified as targets of the auxin-mimicking herbicide picloram.

Tomographic docking suggests the mechanism of auxin receptor TIR1 selectivity [PDF]
Open Biology, 2016 We study the binding of plant hormone IAA on its receptor TIR1, introducing a novel computational method that we call tomographic docking and that accounts for interactions occurring along the depth of the binding pocket.

Final Report [Function of the Arabidopsis TIR1 gene in auxin response] [PDF]
, 2000 During this grant period substantial progress was made in the characterization of the TIR1 gene in Arabidopsis. Studies showed that the TIR1 protein is part of a protein complex that includes AtCUL1, ASK1 and RBX1. This complex, called SCF-TIR1, functions in the ubiquitin-mediated protein degradation pathway.
