Phosphorylation by the stress-activated MAPK Slt2 down-regulates the yeast TOR complex 2

, 2018
Saccharomyces cerevisiae target of rapamycin (TOR) complex 2 (TORC2) is an essential regulator of plasma membrane lipid and protein homeostasis. How TORC2 activity is modulated in response to changes in the status of the cell envelope is unclear. Here we

The ubiquitin system and jasmonate signaling [PDF]

, 2016
The ubiquitin (Ub) system is involved in most, if not all, biological processes in eukaryotes. The major specificity determinants of this system are the E3 ligases, which bind and ubiquitinate specific sets of proteins and are thereby responsible for ...

Time‐ and space‐resolved transcriptional regulation in Arabidopsis thaliana

Plant Biology, Volume 28, Issue 4, Page 1005-1015, June 2026.
Transcript abundance patterns in time and space of kinases, E3 ligases and transcription factors in Arabidopsis thaliana demonstrate ample room for dynamic and specific regulation of metabolism and stress responses. Abstract General metabolism and responses to internal or external signals are tightly regulated in plants.

Phosphorylation of CENP-A on serine 7 does not control centromere function [PDF]

, 2019
CENP-A is the histone H3 variant necessary to specify the location of all eukaryotic centromeres via its CENP-A targeting domain and either one of its terminal regions.

Stage‐Specific RNA Turnover Drives Small RNA Dynamics in Arabidopsis–Colletotrichum Interactions

Plant Direct, Volume 10, Issue 5, May 2026.
ABSTRACT Small RNAs (sRNAs) are key regulators of plant defense and have been implicated in cross‐kingdom interactions with pathogens. The hemibiotrophic fungus Colletotrichum higginsianum infects Arabidopsis thaliana through three stages: appressorial penetration, biotrophy, and necrotrophy.

The Tetrazole Analogue of the Auxin Indole-3-acetic Acid Binds Preferentially to TIR1 and Not AFB5 [PDF]

ACS Chemical Biology, 2018
Auxin is considered one of the cardinal hormones in plant growth and development. It regulates a wide range of processes throughout the plant. Synthetic auxins exploit the auxin-signalling pathway and are valuable as herbicidal agrochemicals. Currently, despite a diversity of chemical scaffolds all synthetic auxins have a carboxylic acid as the active ...

Indole-3-propionic acid regulates lateral root development by targeting auxin signaling in Arabidopsis

iScience
Summary: Indole-3-propionic acid (IPA) is known to be a microbe-derived compound with a similar structure to the phytohormone auxin (indole-3-acetic acid, IAA). Previous studies reported that IPA exhibited auxin-like bioactivities in plants. However, the

The miR319/bHLH094 Module Regulates Creeping Bentgrass Thermotolerance by Modulating Auxin Biosynthesis and Signalling Pathway

Plant Biotechnology Journal, Volume 24, Issue 5, Page 3201-3218, May 2026.
ABSTRACT MicroRNA319 (miR319) has been demonstrated to regulate plant development and responses to stress such as drought and salt. However, its role in thermotolerance, particularly in cool season grasses, remains unclear. Here we report that miR319 plays a negative role in heat tolerance of creeping bentgrass (Agrostis stolonifera).

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.

Auxin-inducible protein depletion system in fission yeast

BMC Cell Biology, 2011
Background Inducible inactivation of a protein is a powerful approach for analysis of its function within cells. Fission yeast is a useful model for studying the fundamental mechanisms such as chromosome maintenance and cell cycle.
