The ArcZ small RNA activates SlyA production to control contact-dependent antibacterial killing and diffusible antifungal activity in Dickeya solani

Quentin Dubois, Marcel Sprenger, Sebastian Krautwurst…·Erwan Gueguen

The paper identifies an sRNA regulatory cascade in Dickeya solani that controls both antifungal and antibacterial activities by activating SlyA translation.

Host infection selects for sRNA variants that drive bacterial social cheating

Quentin Dubois, Typhaine Brual, Marcel Sprenger…·Erwan Gueguen

The paper shows that single-nucleotide mutations in the sRNA ArcZ of Dickeya solani generate social cheater variants during potato infection, which exploit a shared metabolic benefit without contributing to it.
