Streptomyces development is involved in the efficient containment of viral infections.

ABSTRACT: The formation of plaques represents the hallmark of phage infection visualizing the clearance of the bacterial lawn in structured environments. In this study, we have addressed the impact of cellular development on phage infection in Streptomyces undergoing a complex developmental life cycle. Analysis of plaque dynamics revealed, after a period of plaque size enlargement, a significant regrowth of transiently phage-resistant Streptomyces mycelium into the lysis zone. Analysis of Streptomyces venezuelae mutant strains defective at different stages of cellular development indicated that this regrowth was dependent on the onset of the formation of aerial hyphae and spores at the infection interface. Mutants restricted to vegetative growth (ΔbldN) featured no signif
