mutant (FM13) deficient in phenazine production were obtained following transposon mutagenesis of PNA1 (Schnider et a1.,1995).
Unlike piggyBac or other transposons, the JcDNV vector enters only the somatic, or body, cells--not the germline, or reproductive, cells--so the next generation will not inherit the genes.

These promoterless genes lie near one end of a modified Tn5 transposon which also encodes kanamycin resistance ([Km.sup.r]).
Sometime long in the past, Zapotec farmers must have selected kernels for reseeding that contained an inhibitor of the mutator transposon, whose effect is thus countered as long as the maize is exclusively inbred, If crossed with other races, however, the mutator transposon can escape to other breeds and act like a genetic time bomb.
Sex pili are formed that enable direct contact between cells and an 11-kb transposon TN1546 subsequently is transferred, inducing resistance to the susceptible bacterium.
Mutation in the existing DNA or acquisition of foreign DNA results in acquired resistance.8 For high-level aminoglycoside resistance (MIC >2000 ug /mL), either ribosomal mutation is acquired or aminoglycoside-modifying enzyme is acquired via plasmid.12 Resistance to chloramphenicol is either enzymatic or plasmid-borne and resistance to high-level erythromycin is the result of transposon encoding macrolide resistance.13 Resistance to glycopeptides can be plasmid-borne or chromosomal and is due to a cluster of genes absent in normal enterococci.14 The MICs used for enterococcal treatment have been identified (Table).
