Members of the Roseobacter clade of alpha-proteobacteria are among the most abundant and ecologically relevant marine bacteria. Bacterial isolates and gene sequences derived from this taxonomic lineage have been retrieved from marine environments ranging from sea ice to open ocean mixed layer to tropical coral reefs, and in ecological niches ranging from free-living plankton to sponge symbiont to biofilm pioneer. Although roseobacters are cosmopolitan in the marine environment, their numbers and activity significantly rise with increases in the population density of phytoplankton [1,2], suggesting that these bacteria are highly adapted to engage in these symbioses. This review examines the molecules and phenotypes of roseobacters that are important in establishing and maintaining the symbioses between roseobacters and phytoplankton.
α-变形菌纲的玫瑰杆菌群成员是最丰富和具有生态相关性的海洋细菌之一。从海洋环境中分离出的细菌和从该分类群中获得的基因序列，这些环境范围从海冰到开阔海洋混合层到热带珊瑚礁，生态位从自由生活的浮游生物到海绵共生体到生物膜先驱者不等。尽管玫瑰杆菌在海洋环境中是世界性的，但它们的数量和活性随着浮游植物种群密度的增加而显著增加[1,2]，这表明这些细菌非常适应参与这些共生关系。这篇综述考察了玫瑰杆菌在建立和维持玫瑰杆菌与浮游植物之间共生关系中重要的分子和表型。
