Abstract
ABSTRACTStreptomycesare renowned for their prolific production of specialized metabolites with applications in medicine and agriculture. These multicellular bacteria present a sophisticated developmental cycle, and play a key role in soil ecology. Little is known aboutStreptomyces-phage interactions and the impact of phages onStreptomycesphysiology. In this study, we investigated the conditions governing the expression and production of ‘Samy’, a prophage found inStreptomyces ambofaciensATCC 23877. This siphoprophage is produced simultaneously with the activation of other mobile genetic elements. We show that Samy production increases bacterial dispersal underin vitrostress conditions. Altogether, we unveiled a new property of a bacteriophage infection that it is closely linked to the multicellular community life ofStreptomycesbacteria.Graphical summaryIMPORTANCEStreptomycesare multicellular bacteria producing valuable metabolites, including antibiotics, with applications in medicine and agriculture. In this study, we characterized a novel temperate phage, named Samy, and its impact on bacteria physiology. Remarkably, the presence and production of Samy increases bacterial dispersal underin vitrostress conditions. This constitutes an emerging property associated with bacteriophage infection that might enhance the spread of the species. Our study reveals a new aspect of bacteriophage infection in the context of multicellular aggregate dynamics.
