Impact of Hanks Kinase‐Dependent Phosphorylation of CodY on the Physiology and Virulence in Bacillus cereus

MicrobiologyOpen, Volume 14, Issue 6, December 2025.
CodY is a global regulator whose phosphorylation at serine 215 by PrkC/YbdM alters its DNA binding, thereby modulating gene expression and impacting motility, biofilm formation, cytotoxicity, and pathogenicity in Bacillus cereus, suggesting a conserved regulatory mechanism in Firmicutes ABSTRACT CodY acts as a key regulatory protein involved in ...

Foundation species loss alters algal community structure and dynamics at a trailing range edge

Journal of Ecology, Volume 113, Issue 12, Page 3858-3872, December 2025.
These findings show the indirect effects of climate‐driven population loss, through changes in ecological interactions such as competition, that can propagate through entire communities. Given kelp underpin the wider temperate reef food web, this will likely have serious knock‐on consequences at the ecosystem level.

Exploring the Cultivation of Ulva intestinalis in Low-Salinity Environments of the Baltic Sea

Oceans
Ulva intestinalis holds promise for sustainable aquaculture in the Baltic Sea, but success has so far been limited by high environmental variability.

Multiple hybrid zones involving four Cardamine species and their triploid progeny: watching allopolyploid speciation in action?

New Phytologist, Volume 248, Issue 5, Page 2616-2635, December 2025.
Summary Hybrid zones provide excellent opportunities to study evolutionary processes linked to interspecific gene flow, including introgression, genetic erosion, polyploid establishment, and speciation. The genus Cardamine (Brassicaceae) serves as an excellent model for polyploid evolution, including one of the few well‐documented neo‐allopolyploid ...

Chromatin dynamics during plant sexual reproduction

Frontiers in Plant Science, 2014
Plants have the remarkable ability to establish new cell fates throughout their life cycle, by contrast to most animals that define all cell lineages during embryogenesis.

The use of germinants to potentiate the sensitivity of Bacillus anthracis spores to peracetic acid [PDF]

, 2016
Elimination of Bacillus anthracis spores from the environment is a difficult and costly process due in part to the toxicity of current sporicidal agents.

Transcriptome Profiling of Resistance Gene Analogs in Soybean's Cross‐Tolerance to Water Limitation and Rust Stress

Food and Energy Security, Volume 14, Issue 5, September/October 2025.
ABSTRACT Asian soybean rust (ASR), caused by Phakopsora pachyrhizi, is the most destructive foliar disease of soybean, with yield losses up to 90%. With climate change intensifying drought and expanding disease incidence, it is critical to understand how combined abiotic and biotic stresses influence plant defense.

A Fossil Record of Spores before Sporophytes

Diversity
Because their resistant, sporopolleninous walls preserve a record of morphogenetic change during spore formation, fossil cryptospores provide a direct physical record of the evolution of sporogenesis during the algal–plant transition.

Seasonal and Spatial Variation in the Growth, Biomass Production, Mortality and Potential Blue Carbon Production of Golden Kelp (Ecklonia radiata) Off Eastern Australia

Austral Ecology, Volume 50, Issue 9, September 2025.
ABSTRACT Kelp removes carbon from the oceans as it grows, with the potential for long‐term removal of this ‘blue carbon’ through the sequestration of kelp detritus in deep offshore sediments and waters. However, understanding the magnitude of kelp's blue carbon potential requires more detailed information about kelp growth, biomass production, and ...
