Ruegeria Ruegeria pomeroyi

Description and Significance

Ruegeria pomeroyi is a gram negative, rod shaped, aerobe. R. pomeroyi is found in costal oceanic ecosystems. R. pomeroyi is a key player in these ecosystems because of its ability to breakdown dimethylsulfoniopropionate (DMSP), a sulfur based osmolyte closely associated with algae and seaweed. When breaking down DMSP R. pomeroyi can use the sulfur to make useful sulfur based amino acids. The real importance of R. pomeroyi is that even though degrading DMSP is not specific to this species, R. pomeroyi has been the key to unlocking the genes that are linked to the degradation of DMSP.

Genome Structure

R. pomeroyi's chromosome contains 4,109,437 bp and has a circular chromosome, as well as a 491,611 bp circular megaplasmid. The sequence gives a good insight into how R. pomeroyi's role in the carbon cycle in the ocean (Rivers, 2014).
