"* Roseobacter Shiba 1991 emend. Martens et al. 2006" . . "In taxonomy, Roseobacter is a genus of the Rhodobacteraceae. The Roseobacter clade falls within the {alpha}-3 subclass of the class Proteobacteria. The first strain descriptions appeared in 1991 which described members Roseobacter litoralis and Roseobacter denitrificans, both pink-pigmented bacteriochlorophyll a-producing strains isolated from marine algae. The role members of the Roseobacter lineage play in marine biogeochemical cycles and climate change cannot be overestimated."@en . . "darkgrey"@en . . . .
