CapP mediates the structural formation of biofilm-specific pili in the opportunistic human pathogen Bacillus cereus

This paper identifies BC1280 as an essential chaperone for biofilm-specific pili assembly in B. cereus, showing its role in filament formation and regulation of EPS expression.

Molecular response to multiple trace-element contamination of the European sardine

This study investigates the molecular response of European sardines to trace-element contamination, finding upregulated stress and immune pathways and potential biomarkers for monitoring sardine health.

Cyclo(Pro-Tyr) elicits conserved cellular damage in fungi by targeting the ATPase Pma1 in plasma membrane domains

This study identifies cyclo(Pro-Tyr) as a metabolite that disrupts eukaryotic cellular membranes by targeting Pma1 ATPase in microdomains, inducing oxidative stress and membrane fluidity changes in fungi and nematodes.

Potential climate change effects on the distribution of urban and sylvatic dengue and yellow fever vectors

The paper assesses how climate change may affect the distribution of dengue and yellow fever vectors, identifying areas where transmission risk could increase.

Molecular characterization of the N-terminal half of TasA during functional amyloid assembly and its contribution to Bacillus subtilis biofilm formation

This study investigates the N-terminal half of TasA in Bacillus subtilis, identifying sequence features critical for amyloid assembly and biofilm formation.

Digestive exophagy of Bacterial Biofilms by an Amoeba Predator is Mediated by Specific Biofilm Recognition

This study shows that E. histolytica degrades bacterial biofilms via digestive exophagy, involving cysteine proteases and stress response modulation.

A non-invasive method for time-lapse imaging of microbial interactions and biofilm dynamics

This paper introduces BacLive, a non-invasive method for time-lapse imaging of microbial interactions and biofilm dynamics using fluorescence microscopy and ImageJ processing.

Denitrification in foraminifera has ancient origin and is complemented by associated bacteria

The paper shows denitrification genes are conserved in foraminifera and their microbiome complements the pathway, revealing an ancient origin of this trait in these organisms.

Mutualistic interactions between B. subtilis and seeds dictate plant development

This study shows that B. subtilis interacts with seeds through its extracellular matrix components, influencing lipid metabolism and plant growth programs.

Sporulation is dispensable for the vegetable-associated life cycle of the human pathogen Bacillus cereus

This study shows that sporulation is not necessary for B. cereus to cause food poisoning in vegetables like endives, challenging current detection protocols based on spores.

Chemical interplay and complementary adaptative strategies toggle bacterial antagonism and co-existence

The paper investigates how chemical interactions and mutations in two plant-beneficial bacteria influence their antagonism and coexistence.

Biofilm formation displays intrinsic offensive and defensive features of Bacillus cereus

The paper shows that Bacillus cereus forms biofilms with defensive and offensive subpopulations, using RNAseq and iTRAQ to reveal metabolic and functional differences.

Dual functionality of the TasA amyloid protein in Bacillus physiology and fitness on the phylloplane

This study identifies two distinct roles of TasA in Bacillus subtilis: structural ECM formation and membrane dynamics stabilization during stationary phase, impacting biofilm formation and phylloplane survival.

Extracellular matrix components are required to protect Bacillus subtilis colonies from T6SS-dependent Pseudomonas invasion and modulate co-colonization of plant

This study shows that the extracellular matrix protects Bacillus subtilis from Pseudomonas invasion via T6SS and influences their co-colonization on plants.
