Genome analysis revealed the presence of a CRISPR-Cas system in a predatory bacterium, suggesting its ecological role in northern soils.
<ns3:p>Predatory bacteria are abundant in soil, but their diversity and functions remain not fully understood, especially in subarctic regions. Here, we report strain 1-FT3.2, a predatory bacterium obtained from peatland soil in Northern Finland (Pallas, 68 °N). The bacterium was cultivated on <ns3:italic>Mucilaginibacter cryoferens</ns3:italic> FT3.2 as prey. Although a pure culture of strain 1-FT3.2 was not obtained, its draft genome was assembled from sequencing reads derived from the co-culture with its prey. The draft genome of 1-FT3.2 is 7.2 Mb in length and 81% complete. Genome analyses suggested that 1-FT3.2 belongs to the family <ns3:italic>Polyangiaceae</ns3:italic> (phylum <ns3:italic>Myxococcota</ns3:italic>), which comprises predatory bacteria. The genome annotation revealed (near-)complete metabolic modules of central carbon metabolism and aerobic respiration. Two proviral regions were predicted in the draft genome, both putatively representing tailed phages of the class <ns3:italic>Caudoviricetes.</ns3:italic> Several CRISPR-Cas system proteins were also identified. The draft genome sequence could be used in future comparative studies assessing the diversity of predatory bacteria in northern soils or other environments.</ns3:p>
