Deciphering the biology and chemistry of the mutualistic partnership between Bacillus velezensis and the arbuscular mycorrhizal fungus Rhizophagus irregularis

This study investigates the mutualistic interaction between Bacillus velezensis and Rhizophagus irregularis, revealing how they modulate each other's metabolism to enhance plant protection.

The fate of bacterial secondary metabolites in the rhizosphere: Streptomyces degrades and feeds on cyclic lipopeptides produced by competitors

This study shows Streptomyces venezuelae degrades cyclic lipopeptides from competitors like Bacillus and Pseudomonas, using them as nutrients and altering microbial interactions.

Mechanosensing and Sphingolipid-Docking Mediate Lipopetide-Induced Immunity in Arabidopsis

This study identifies that lipopeptide elicitor surfactin activates immunity in Arabidopsis by docking into sphingolipid domains, causing membrane deformation and mechanosensitive ion channel activation, leading to resistance against B. cinerea.

Surfactin stimulated by pectin molecular patterns and root exudates acts as a key driver of Bacillus-plant mutualistic interaction

This paper shows that Bacillus velezensis produces surfactin in response to pectin and root exudates, which enhances biofilm formation, motility, and plant immunity.

Chelator sensing and lipopeptide interplay mediates molecular interspecies interactions between soil bacilli and pseudomonads

The paper investigates molecular interactions between Bacillus velezensis and Pseudomonas, showing how chelator sensing and lipopeptides influence competitive outcomes in the rhizosphere.

The bacterial virulence factors rhamnolipids and their (R)-3-hydroxyalkanoate precursors activate Arabidopsis innate immunity through two independent mechanisms

This paper shows that rhamnolipids and their (R)-3-hydroxyalkanoate precursors activate Arabidopsis immunity through two distinct mechanisms involving different receptors and signaling pathways.
