SapB and the rodlins are required for development of Streptomyces coelicolor in high osmolarity media

Abstract Streptomyces coelicolor produces spore-forming aerial hyphae after a period of vegetative growth. These aerial structures are decorated with a hydrophobic coating of rodlets consisting of chaplins and rodlins. Here, we show that rodlins and the surface-active peptide SapB are essential for...

Description
Summary:Abstract Streptomyces coelicolor produces spore-forming aerial hyphae after a period of vegetative growth. These aerial structures are decorated with a hydrophobic coating of rodlets consisting of chaplins and rodlins. Here, we show that rodlins and the surface-active peptide SapB are essential for development during growth in a medium with high osmolarity. To this end, both vegetative and aerial hyphae secrete SapB, whereas rodlins are only secreted by the spore-forming aerial hyphae.
