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.

A novel mechanism of auxin habituation: upregulation of auxin receptor TRANSPORT INHIBITOR RESPONSE 1 allows cell proliferation independent of external auxin. [PDF]

New Phytol
Summary Exogenously applied auxins are essential for establishing cell lines in tissue cultures and maintaining their proliferation. Cell lines may develop the ability to proliferate even in media lacking auxin, they may become auxin‐habituated. This study investigated the mechanisms underlying this process.

A comprehensive genetic analysis of candidate genes regulating response to Trypanosoma congolense infection in mice. [PDF]

PLoS Neglected Tropical Diseases, 2010
African trypanosomes are protozoan parasites that cause "sleeping sickness" in humans and a similar disease in livestock. Trypanosomes also infect laboratory mice and three major quantitative trait loci (QTL) that regulate survival time after infection ...

Engineering the auxin-inducible degron system for tunable in vivo control of organismal physiology [PDF]

Nature Communications
The auxin-inducible degron (AID) system is designed for the rapid and near-complete degradation of a specific target protein in vivo. However, to understand the dynamics of complex physiological networks, researchers often need methods that produce ...

Development of functional fermented feed additives enhanced with xylo-oligosaccharides and yeast proteins from corn cobs [PDF]

Journal of Animal Science and Technology
The use of agricultural by-products, such as corn cobs, has gained significant attention as a sustainable and promising strategy for developing functional feed additives.

Primed to Burst: Corepressors Coordinate Transcriptional Activation and Efficient Switching Between Cell States. [PDF]

Bioessays
We hypothesize that the TPL corepressor (and likely others) acts as a transcriptional linchpin, stabilizing a state similar yet distinct from the metazoan paused state by recruiting Mediator and other components needed to initiate and coordinate transcriptional bursts across multiple genes.

HSP90 regulates temperature-dependent seedling growth in Arabidopsis by stabilizing the auxin co-receptor F-box protein TIR1

Nature Communications, 2016
A moderate increase in temperature promotes hypocotyl elongation in Arabidopsis. Here, Wang et al.show that elevated temperature not only increases auxin biosynthesis but also acts via the co-chaperones HSP90 and SGT1 to stabilize the TIR1 auxin receptor.

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.

miRNA-targeted auxin nuclear signalling elements orchestrate flower fate and drought response in yellow lupine [PDF]

Scientific Reports
Yellow lupine (Lupinus luteus L.) is a promising protein crop, but domestication has increased flower abscission. Flowers in higher whorls are more likely to abscise, providing a model to study factors influencing flower fate before abscission zone ...

Regulation of SCFTIR1/AFBs E3 ligase assembly by S-nitrosylation of Arabidopsis SKP1-like1 impacts on auxin signaling [PDF]

Redox Biology, 2018
The F-box proteins (FBPs) TIR1/AFBs are the substrate recognition subunits of SKP1–cullin–F-box (SCF) ubiquitin ligase complexes and together with Aux/IAAs form the auxin co-receptor.
