Functional divergence of flagellar type III secretion system: A case study in a non-flagellated, predatory bacterium.

ABSTRACT: The lack of functional flagella and the ability to prey upon other microorganisms are well-known traits of Lysobacter enzymogenes, a plant beneficial bacterial species. Here, we report a possible link between these two traits in the model strain L. enzymogenes OH11 (OH11). The genome of OH11 encompasses several homologous genes involved in the flagellum formation but it lacks a functional fliC, encoding the flagellin. Despite the lack of the main component of the flagellum, OH11 genome includes genes involved in the flagellar type III secretion system (FT3SS), which is commonly deployed by flagellated bacteria to transport flagellar subunit proteins. To understand the role played by FT3SS in OH11, we showed that the remaining FT3SS genes were expressed under laboratory
