Genetical rearrangements in Azospirillum brasilense induced by the plasmid PJB4JI

The present work was conducted with the initial purpose of looking for the characterization of Azospirillum brasilense strain ATCC 29.145 mutants induced by insertions of the transposon Tn-5. The strategy used to transfer such mobile element was based on the vector named pJB4JI
