A newly isolated roseophage represents a distinct member of Siphoviridae family.

ABSTRACT:

Background

Members of the Roseobacter lineage are a major group of marine heterotrophic bacteria because of their wide distribution, versatile lifestyles and important biogeochemical roles. Bacteriophages, the most abundant biological entities in the ocean, play important roles in shaping their hosts' population structures and mediating genetic exchange between hosts. However, our knowledge of roseophages (bacteriophages that infect Roseobacter) is far behind that of their host counterparts, partly reflecting the need to isolate and analyze the phages associated with this ecologically important bacterial clade.

Methods

vB_DshS-R4C (R4C), a novel virulent roseophage that infects Dinoroseobacter shibae DFL12^T, was isolated with the double-layer agar method. The phag
