Draft Genome Sequences of Three Bacterial Isolates from Cultures of the Marine Diatom Thalassiosira rotula

Phytoplankton often both provision and depend on heterotrophic bacteria. In order to investigate these relationships further, we sequenced draft genomes of three bacterial isolates from cultures of the marine diatom Thalassiosira rotula to identify metabolic functions that may support interactions with T. rotula .
