Abstract
In taxonomy, Ruegeria is a genus of the Rhodobacteraceae. This genus was formerly known as the marine Agrobacterium before they were reclassified in 1998. It bears in fact the name of Hans-Jürgen Rüger, a German microbiologist, for his contribution to the taxonomy of marine species of Agrobacterium.
Characteristics
The genus is characterised by members who are:
Gram-negative (like all Proteobacteria) ovoid to rod-shaped cells 0.6–1.6 × 1.0–4.0 µm motile by polar flagella, or nonmotile non-sporeformers aerobic oxidase and catalase positive are incapable of photosynthetic growth bacteriochlorophyll a is absent major quinone is ubiquinone 10 mol% G+C of the DNA is 55–59 member of the family Rhodobacteraceae, which is phenotypically, metabolically, ecologically diverse and defined based on 16S sequences data
Phylogenetically it is very close to the genus Silicibacter, but the two remain separate species due to phenotypic differences — two species for which this is problematic are Ruegeria lacuscaerulensis and Ruegeria pomeroyi.YI (H.), LIM (Y.W.) and CHUN (J.): Taxonomic evaluation of the genera Ruegeria and Silicibacter: a proposal to transfer the genus Silicibacter Petursdottir and Kristjansson 1999 to the genus Ruegeria Uchino et al. 1999.

Small non-coding RNAs
Highly abundant bacterial small RNAs have been shown to be present in the bacteria subjected to chronic nutrient limitation. In Ruegeria pomeroyi RNAseq analysis identified 99 putative sRNAs. The bacterial sRNAs regulatory mechanisms are typically based on direct RNA-RNA interaction with a target mRNA. The target gene groups identified by Rivers et al. were genes involved in transport, genes mediating cell-cell interactions, signal transduction and transcriptional regulation.
