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

SH6-1 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 group within the alphaproteobacterial family . Here we describe the draft genome sequence and annotation of the type strain SH6-1. 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 but points also to interactions with prokaryotic or eukaryotic organisms.
