Tn5 mutagenesis and insertion replacement in Azotobacter vinelandii.

Plasmid - 1 Jan 1991

Contreras A, Maldonado R, Casadesus J

Abstract excerpt

Tn5 insertion mutants of Azotobacter vinelandii were isolated using vectors pJB4JI (IncP) and pGS9 (IncN). A procedure to replace Tn5 (Kmr) by its nontransposing derivative Tn5-131 (Tcr) was developed. For the replacement, a ColEl derivative harboring Tn5-131 (pRZ131) was conjugally mobilized by the IncN plasmid pCU101 into A. vinelandii strains containing Tn5. Both plasmids are unable to be maintained in A....
