Phytosulfokine signalling blocks mycotoxin toxicity in Arabidopsis and mediates suppression of cell death activated by bacterial microbe‐associated molecular patterns

open access: yesNew Phytologist, Volume 249, Issue 5, Page 2515-2530, March 2026.
Summary Fumonisin B1 (FB1) is a mycotoxin that disrupts ceramide biosynthesis and kills plants. Prior activation with bacterial microbe‐associated molecular patterns (MAMPs), such as components of bacterial flagella, effectively suppresses FB1‐induced cell death.

Controlling Geminiviruses before Transmission: Prospects

open access: yesPlants, 2020
Whitefly (Bemisia tabaci)-transmitted Geminiviruses cause serious diseases of crop plants in tropical and sub-tropical regions. Plants, animals, and their microbial symbionts have evolved complex ways to interact with each other that impact their life ...

Heat Shock Proteins in Aquatic Larvae: Nutritional and Live Feed Modulation of Chaperone‐Mediated Stress Physiology in Fish and Shellfish

open access: yesReviews in Aquaculture, Volume 18, Issue 2, March 2026.
ABSTRACT Heat shock proteins (HSPs) are highly conserved molecular chaperones that maintain proteostasis under environmental and physiological stress. In aquaculture research, HSP responses have been studied primarily in relation to temperature, salinity, pollutants, and pathogens in juvenile and adult stages, whereas the nutritional regulation of HSP ...

Catalysis of Protein Folding by Chaperones Accelerates Evolutionary Dynamics in Adapting Cell Populations [PDF]

open access: yes, 2013
Although molecular chaperones are essential components of protein homeostatic machinery, their mechanism of action and impact on adaptation and evolutionary dynamics remain controversial. Here we developed a physics-based ab initio multi-scale model of a

ZNRD2 Mediated Nucleoprotein Aggregation Impairs Respiratory Syncytial Virus Replication

open access: yesAdvanced Science, Volume 13, Issue 12, 27 February 2026.
During RSV infection, nucleoprotein (N) forms RNA‐bound oligomers. The host protein ZNRD2 binds to these oligomers, promoting their transition into insoluble aggregates. These aggregates simultaneously sequester functional N to restrict viral production and disrupt chaperonin assembly quality control by interfering with ZNRD2's role as an adaptor ...

Chaperonin of Group I: Oligomeric Spectrum and Biochemical and Biological Implications

open access: yesFrontiers in Molecular Biosciences, 2018
Chaperonins play various physiological roles and can also be pathogenic. Elucidation of their structure, e.g., oligomeric status and post-translational modifications (PTM), is necessary to understand their functions and mechanisms of action in health and

Effects of confinement and crowding on folding of model proteins

open access: yes, 2008
We perform molecular dynamics simulations for a simple coarse-grained model of crambin placed inside of a softly repulsive sphere of radius R. The confinement makes folding at the optimal temperature slower and affects the folding scenarios, but both ...

A dsRNA Viral Transcriptional Regulator Evades Innate Immunity by Hijacking Host CoTranscription Factor DHX9

open access: yesAdvanced Science, Volume 13, Issue 10, 18 February 2026.
This study identifies a new viral mechanism by a viral protein σ3 that functions as a vTR to suppress NF‐κB gene expression via its direct interaction with the host helicase DHX9. Through their interaction, σ3 not only impairs the initial recruitment of Pol II but also affects Pol II pause‐release and ultimately suppresses NF‐κB gene expression ...
