Ruegeria [SEP] parent taxon
Ruegeria
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
for which this is problematic are "Ruegeria lacuscaerulensis" and "Ruegeria pomeroyi".
Two species that have been removed from the genus are Marinovum algicola (Ruegeria algicola) and Thalassobius gelatinovorus (Ruegeria gelatinovora).
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.
