Molecular Chaperone Networks in Plants: Maintaining Proteostasis and Enhancing Stress Resilience for Crop Improvement

Plant, Cell &Environment, EarlyView.
ABSTRACT Molecular chaperones play a central role in the plant proteostasis machinery by aiding the folding of nascent proteins, preventing aggregation, and repairing or degrading damaged proteins. These functions are especially essential during abiotic and biotic stress, which can destabilise cellular proteins and disrupt metabolic homoeostasis.

Mechanism of Auxin Perception by the SCF‐TIR1 Ubiquitin Ligase

The FASEB Journal, 2008
The plant hormone auxin regulates almost every aspect of plant physiology and has fascinated biologists since Darwin's time. How plants sense and respond to auxin, however, remained mysterious until recently. In 2005, the substrate receptor subunit of the plant SCF‐TIR1 ubiquitin ligase complex was identified as the long‐sought auxin receptor.

Auxin-dependent interaction of IAA8 with the TIR1 auxin receptor.

, 2012
(A) Yeast (EGY48::pJK103) cells were co-transformed with bait plasmid, which contained a LexA DNA-binding domain (BD)-TIR1 fusion (BD-TIR1) in pEG202, and prey plasmid, which contained activation domain (AD)-Aux/IAA fusions (AD-Aux/IAA) in pJG4-5.

The vesicle trafficking R‐SNARE VAMP714 connects auxin responses, ROS and ion homeostasis in Arabidopsis under salt stress

New Phytologist, Volume 251, Issue 1, Page 207-227, July 2026.
Network of VAMP714‐dependent interactions during salt stress. Summary Plant responses to salt stress include an altered root architecture mediated by ion imbalances, reactive oxygen species (ROS) accumulation, and altered hormonal responses. Auxin is implicated in these processes.

Flexibility of intrinsically disordered degrons in AUX/IAA proteins reinforces auxin co-receptor assemblies

Nature Communications, 2020
Auxin-mediated recruitment of AUX/IAAs by the F-box protein TIR1 prompts rapid AUX/IAA ubiquitylation and degradation. By resolving auxin receptor topology, the authors show that intrinsically disordered regions near the degrons of two Aux/IAA proteins ...

Pseudomonas volatiles shape the root transcriptome and microbiome to promote plant growth under drought

New Phytologist, Volume 251, Issue 1, Page 405-423, July 2026.
Summary Volatile organic compounds (VOCs) emitted by soil bacteria influence interactions with other soil microbes and plants. While their potential as plant growth promoters is well recognized, their role in promoting plant resilience to abiotic stress and the underlying molecular mechanisms remain poorly understood.
