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 ...

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).

ComputationAuxins are chemical compounds of wide interest, mostly due to their role in plant metabolism and development. Synthetic auxins have been used as herbicides for more than 75 years and low toxicity in humans is one of their most advantageous features ...

Role of TIR1/AFB family genes during grafting in Carya cathayensis
Frontiers in Plant ScienceAuxins play significant roles in plant growth and development. The transporter inhibitor response1/auxin signaling F-box (TIR1/AFB) gene family encodes the auxin receptor proteins and plays an essential role in the auxin signaling pathway.

BMC Plant Biology, 2023 Background The plant hormone auxin is widely involved in plant growth, development, and morphogenesis, and the TIR1/AFB and AUX/IAA proteins are closely linked to rapid auxin response and signal transmission.

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 ...

A Super Strong Engineered Auxin–TIR1 Pair [PDF]
Plant and Cell Physiology, 2018 Auxin regulates diverse aspects of plant growth and development through induction of the interaction between TRANSPORT INHIBITOR RESPONSE 1/AUXIN SIGNALING F-BOX proteins (TIR1/AFBs) and AUXIN/INDOLE-3-ACETIC ACID (Aux/IAA) co-receptor proteins and the subsequent transcriptional regulation.

Oligomerization of SCFTIR1 Is Essential for Aux/IAA Degradation and Auxin Signaling in Arabidopsis. [PDF]
PLoS Genetics, 2016 The phytohormone auxin is a key regulator of plant growth and development. Molecular studies in Arabidopsis have shown that auxin perception and signaling is mediated via TIR1/AFB-Aux/IAA co-receptors that assemble as part of the SCFTIR1/AFB E3 ubiquitin-

GIGANTEA regulates lateral root formation by modulating auxin signaling in Arabidopsis thaliana
Plant Signaling & Behavior, 2022 Lateral root (LR) formation is a vital organogenetic process that determines the root architecture in plants. The number of root branches governs the degree of anchorage, efficiency of nutrients acquisition, and water uptake.

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 ...
