The Arabidopsis Auxin Receptor F-Box Proteins AFB4 and AFB5 Are Required for Response to the Synthetic Auxin Picloram

G3: Genes, Genomes, Genetics, 2016
The plant hormone auxin is perceived by a family of F-box proteins called the TIR1/AFBs. Phylogenetic studies reveal that these proteins fall into four clades in flowering plants called TIR1, AFB2, AFB4, and AFB6. Genetic studies indicate that members of

S-Nitrosation of E3 Ubiquitin Ligase Complex Components Regulates Hormonal Signalings in Arabidopsis

Frontiers in Plant Science, 2022
E3 ubiquitin ligases mediate the last step of the ubiquitination pathway in the ubiquitin-proteasome system (UPS). By targeting transcriptional regulators for their turnover, E3s play a crucial role in every aspect of plant biology.

The pea branching RMS2 gene encodes the PsAFB4/5 auxin receptor and is involved in an auxin-strigolactone regulation loop [PDF]

, 2017
Strigolactones (SLs) are well known for their role in repressing shoot branching. In pea, increased transcript levels of SL biosynthesis genes are observed in stems of highly branched SL deficient (ramosus1 (rms1) and rms5) and SL response (rms3 and rms4)

Towards an integrated molecular understanding of plant hormones

Journal of Integrative Plant Biology, EarlyView.
This review offers a comprehensive overview of the nine plant hormones, delving into their biosynthesis, transport, signaling and crosstalk mechanisms. Because the complexity of plant hormonal control goes beyond these core elements, additional specific features are discussed. Lastly, this review highlights how fundamental insights drive hormonal‐based

Arabidopsis inositol polyphosphate kinase activities regulate COP9 deneddylation functions in phosphate homeostasis

Journal of Integrative Plant Biology, EarlyView.
Plant phosphate (Pi) homeostasis relies on coordinated activities of the inositol polyphosphate kinases IPK1 and ITPK1, which balance localized InsP7 biosynthesis to control COP9 signalosome (CSN)‐dependent deneddylation of cullin 1 (CUL1). Perturbation of this equilibrium affects the stability of SPX4, a key negative regulator of phosphate starvation ...

HSP90 Stabilizes Auxin-Responsive Phenotypes by Masking a Mutation in the Auxin Receptor TIR1 [PDF]

Plant and Cell Physiology, 2016
Heat shock protein 90 (HSP90) is a molecular chaperone that is required for the function of various substrate proteins, also known as client proteins. It is proposed that HSP90 buffers or hides phenotypic variations in animals and plants by masking mutations in some of its client proteins. However, none of the client proteins with cryptic mutations has

Cis-regulatory elements and transcription factors related to auxin signaling in the streptophyte algae Klebsormidium nitens

Scientific Reports, 2023
The phytohormone auxin affects numerous processes in land plants. The central auxin signaling machinery, called the nuclear auxin pathway, is mediated by its pivotal receptor named TRANSPORT INHIBITOR RESPONSE 1/AUXIN SIGNALING F-BOX (TIR1/AFB).

Is thyroid nodule location associated with malignancy risk? [PDF]

, 2019
PURPOSE: Nodules located in the upper pole of the thyroid may carry a greater risk for malignancy than those in the lower pole. We conducted a study to analyze the risk of malignancy of nodules depending on location.
