| Research Abstract |
A series of variants of transposon Tn5 were constructed by replacement of the 2.7 Kb central segment which encodes kanamycin resistance with various other resistance genes : tetracycline( <Tc^r> ), chloramphenicol( <Cm^r> ), gentamicin( <Gm^r> ), trimethoprim( <Tp^r> ), streptomycin( <Sm^r> ) or ampicillin( <Ap^r> ). This set of new derivatives of Tn5 is useful for insertion mutagenesis and for the tagging of cryptic plasmids in diverse gram-negative bacteria. A thermosensitive replication mutant of the broad-host range transmissible plasmid R388 was also constructed for use as a suicide vector for the delivery of transposable elements.
