Project description:Nereida ignava strain 2SM4(T) (= CECT 5292(T)?=?DSM 16309(T)?=?CIP 108404(T)?=?CCUG 49433(T)) is a marine bacterium belonging to the Roseobacter group of the family Rhodobacteraceae within the class Alphaproteobacteria. The strain was isolated from sea water surrounding cultivated oysters 2-3 miles off the Mediterranean coast near Valencia (Spain) and was phylogenetically related to uncultured clones of gall symbiont bacteria of some species of Prionitis alga. Here we describe the genome sequence and annotation of this organism, the type strain of the single species of this genus. The genome comprised 2,888,349 bp, 2,872 protein-coding genes and 52 RNA genes. The annotation revealed the capacity to produce bacteriocins, vitamins and auxins. Besides, it contained sulfur cycling related genes.
