Biogeography of pLA6_12-like plasmids. Sampling locations of Roseobacter group isolates are shown in squares. Locations where metagenomes have been obtained are shown in circles and triangles. Integration cassette motifs are indicated by a color code consistent with Fig. 2. pLA6_12-like plasmids were found exclusively in marine environments, but scattered across the world. Black triangles represent metagenome fragments, which encode pLA6_12-like repL genes, but are too incomplete to allow conclusions on the respective integration cassette.
