Role of RpoN from Labrenzia aggregata LZB033 (Rhodobacteraceae) in Formation of Flagella and Biofilms, Motility, and Environmental Adaptation.

ABSTRACT: Labrenzia aggregata LZB033 (Rhodobacteraceae), which produces dimethylsulfoniopropionate (DMSP) and reduces nitrate to nitrogen, was isolated from seawater of the East China Sea. Its genome encodes a large number of transcriptional regulators which may be important for its adaptation to diverse marine environments. The alternative σ54 factor (RpoN) is a central regulator of many bacteria, regulating the transcription of multiple genes and controlling important cellular functions. However, the exact role of RpoN in Labrenzia spp. is unknown. In this study, an in-frame rpoN deletion mutant was constructed in LZB033, and the function of RpoN was determined. To systematically identify RpoN-controlled genes, we performed a detailed analysis of gene expression differences between the wild-type s
