Complete Genome Sequence of Loktanella vestfoldensis Strain SMR4r, a Novel Strain Isolated from a Culture of the Chain-Forming Diatom Skeletonema marinoi

We report here the genome sequence of Loktanella vestfoldensis strain SMR4r, isolated from the marine diatom Skeletonema marinoi strain RO5AC. Its 3,987,360-bp genome consists of a circular chromosome and two circular plasmids, one of which appears to be shared with an S. marinoi-associated Roseovarius species.
