Plasmid diversity in arctic strains of Psychrobacter spp.
Six strains of Psychrobacter spp. isolated from guano of little auks collected on Spitsbergen island (Arctic) carried nine plasmids that were fully sequenced. These replicons (ranging in size from 2917 to 14924 bp) contained either repA (ColE2-type) or repB (iteron-type) replication systems of a rel...
