StrR is streptomycin resistant; CmR is chloramphenicol resistant; KmR is kanamycin resistant; HgR is mercury resistant; ZeR is zeocin resistant; Ts is temperature sensitive; NalR is nalidixic acid resistant and AmR is ampicillin resistant. UV- is UV-inducible cell-sensitising function abolished; tra- is conjugative transfer deficient mutant.
