Genome sequence of Planktotalea frisia type strain (SH6-1(T)), a representative of the Roseobacter group isolated from the North Sea during a phytoplankton bloom

Planktotalea frisia SH6-1(T) Hahnke et al. (Int J Syst Evol Microbiol 62:1619-24, 2012) is a planktonic marine bacterium isolated during a phytoplankton bloom from the southern North Sea. It belongs to the Roseobacter group within the alphaproteobacterial family Rhodobacteraceae. Here we describe the draft genome sequence and annotation of the type strain SH6-1(T). The genome comprises 4,106,736 bp and contains 4128 protein-coding and 38 RNA genes. The draft genome sequence provides evidence for at least three extrachromosomal elements, encodes genes for DMSP utilization, quorum sensing, photoheterotrophy and a type IV secretion system. This indicates not only adaptation to a free-living lifestyle of P. frisia but points also to interactions with prokaryotic or eukaryotic organisms.
