infA-based plasmid selection using different plasmid replication origins. The strain HS996-infA-pir + was transformed with plasmids differing only in the origin of replication, and subsequently streaked on LB-agar with and without arabinose supplementation. The empty strain, without an infA plasmid, showed no growth in the absence of arabinose. The strains with plasmid grew on both plates
