The bacterial strain SMR4y belongs to the diverse microbiome of the marine diatom Skeletonema marinoi strain R05AC. After assembly of its genome, presented here, and subsequent analyses, we placed it in the genus Sphingorhabdus This strain has a 3,479,724-bp circular chromosome (with 3,340 coding sequences) and no known plasmids.Copyright © 2019 Töpel et al.
Genome Sequence of Arenibacter algicola Strain SMS7, Found in Association with the Marine Diatom Skeletonema marinoi.
Arenibacter algicola strain SMS7 was isolated from a culture of the marine diatom Skeletonema marinoi strain ST54, sampled from top-layer sediments in Kosterfjord, Sweden. Here, we present its 5,857,781-bp genome, consisting of a circular chromosome and one circular plasmid, in all containing 4,932 coding sequences.
Complete genome sequence of novel Sulfitobacter pseudonitzschiae strain SMR1, isolated from a culture of the marine diatom Skeletonema marinoi.
When studying diatoms, an important consideration is the role of associated bacteria in the diatom-microbiome holobiont. To that end, bacteria isolated from a culture of Skeletonema marinoi strain R05AC were sequenced, one of which being bacterial strain SMR1, presented here. The genome consists of a circular chromosome and seven circular plasmids, totalling 5,121,602 bp. After phylotaxonomic analysis and 16S rRNA sequence comparison, we place this strain in the taxon Sulfitobacter pseudonitzschiae on account of similarity to the type strain. The annotated genome suggests similar interactions between strain SMR1 and its host diatom as have been shown previously in diatom-associated Sulfitobacter, for example bacterial production of growth hormone for its host, and breakdown of diatom-derived DMSP by Sulfitobacter for use as a sulfur source.
