A novel family of nonribosomal peptides modulate collective behavior in Pseudovibrio bacteria isolated from marine sponges

This study identifies a novel family of nonribosomal peptides, pseudovibriamides, produced by Pseudovibrio bacteria that modulate motility and biofilm formation, distinct from known surfactant lipopeptides.

Phytotoxic tryptoquialanines produced in vivo by Penicillium digitatum are exported in extracellular vesicles

This study shows that Penicillium digitatum exports tryptoquialanine A, a phytotoxic alkaloid, in extracellular vesicles during citrus infection, inhibiting seed germination and causing tissue damage.

Commensal gut bacteria convert the immunosuppressant tacrolimus to less potent metabolites

This study identifies gut bacteria, particularly Clostridiales, as a source of tacrolimus metabolism, producing less potent metabolites that may explain variable drug exposure after oral dosing.
