Thermosensor Desk Measures Membrane Thickness [PDF]

Biophysical Journal, 2011
The bacterium Bacillus subtilis adjusts the composition of membrane lipids to cope with temperature variations. The histidine kinase DesK is a five-pass transmembrane thermosensor suited to remodel membrane fluidity in B. subtilis according to temperature. To understand the mechanism of sensing, individual transmembrane segments (TMS) were fused to the

Sensing and Filtering Environmental Fluctuations: The Case of Biomolecular Condensates in Plants

Advanced Science, Volume 13, Issue 27, 13 May 2026.
The diversity of plant condensates reflects constraints of sessile organisms to coordinate postembryonic development with environmental adaptation. This review examines how plants employ condensates to integrate temperature, light, redox, and nutrient signals.

SEMI‐1, A Novel Neuronal Selenium‐Binding Protein 1 Homolog Without Methanethiol Oxidase Activity, Modulates Stress Resistance, Lifespan, and Thermotaxis in C. elegans

BioFactors, Volume 52, Issue 3, May/June 2026.
SEMI‐1 is a selenium‐binding protein in C. elegans that, different from its paralog, SEMO‐1, and its human ortholog, SELENBP1, has no enzymatic activity as a methanethiol oxidase. It is expressed in AFD and BAG neurons only and affects nematode thermotaxis, stress resistance, and lifespan.

Thermosensors in eubacteria: role and evolution

Journal of Biosciences, 2007
Temperature is an important physical stress factor sensed by bacteria and used to regulate gene expression. Three different macromolecules have been identified being able to sense temperature: DNA, mRNA and proteins. Depending on the induction mechanism, two different pathways have to be distinguished, namely the heat shock response and the high ...

Driving the catalytic activity of a transmembrane thermosensor kinase

Cellular and Molecular Life Sciences, 2019
DesK is a Bacillus thermosensor kinase that is inactive at high temperatures but turns activated when the temperature drops below 25 °C. Surprisingly, the catalytic domain (DesKC) lacking the transmembrane region is more active at higher temperature, showing an inverted regulation regarding DesK.

Conkazal‐M1 from the MKAVA family of conotoxins: A dual‐function protease inhibitor and neuroactive peptide

Protein Science, Volume 35, Issue 5, May 2026.
Abstract Marine cone snails produce a diverse array of bioactive peptides, known as conotoxins, in their venom. Given their high target potency and specificity, conotoxins are attractive compounds for the development of precision research tools and pharmacological agents.

A genome-wide survey of highly expressed non-coding RNAs and biological validation of selected candidates in Agrobacterium tumefaciens. [PDF]

PLoS ONE, 2013
Agrobacterium tumefaciens is a plant pathogen that has the natural ability of delivering and integrating a piece of its own DNA into plant genome. Although bacterial non-coding RNAs (ncRNAs) have been shown to regulate various biological processes ...

Cross‐Depth Genetic Connectivity Supports the Role of Deep Kelp Forests as Refuge From Climate Change

Diversity and Distributions, Volume 32, Issue 5, May 2026.
ABSTRACT Aim Ocean warming and marine heatwaves are threatening the persistence of kelp forests, but cooler, deeper reefs might act as refuges from which shallow populations can recover. This study aimed to assess the genetic connectivity, diversity, and adaptive structure of deep kelp reefs to evaluate their potential as climate refuges.

Thai Oakleaf Lettuce Phenocopies a Phytochrome B Mutant

Biology
Photomorphogenic development in seedlings may be diagnostic of future plant performance. In this report, we characterize the Thai Oakleaf lettuce genotype, as it exhibited abnormalities in photomorphogenic development that were the most conspicuous under
