摘要:Marinomonas posidonica IVIA-Po-181T Lucas-Elío et al. 2011 belongs to the family Oceanospirillaceae within the phylum Proteobacteria. Different species of the genus Marinomonas can be readily isolated from the seagrass Posidonia oceanica. M. posidonica is among the most abundant species of the genus detected in the cultured microbiota of P. oceanica suggesting a close relationship with this plant, which has a great ecological value in the Mediterranean Sea, covering an estimated surface of 38,000 Km2. Here we describe the genomic features of M. posidonica. The 3,899,940 bp long genome harbors 3,544 protein-coding genes and 107 RNA genes and is a part of the Genomic Encyclopedia of Bacteria and Archaea project.
