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.

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.

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.

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.

Sporulation activated via σW protects Bacillus from a Tse1 peptidoglycan hydrolase T6SS effector

The paper identifies Tse1 as a T6SS effector that triggers sporulation in Bacillus through sigmaW and KinA/KinB, providing a defense mechanism against Pseudomonas.

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.
