Characterization of Tn904 insertions in octopine Ti plasmid mutants of Agrobacterium tumefaciens
Seven Tn904 insertion mutants of pTi Ach5 affecting Agrobacterium tumefaciens virulence were studied. The mutant character was shown to be plasmid borne. Four of these mutants were avirulent and carried an insertion in restriction endonuclease HpaI fragment 12, a 3.3-megadalton fragment, which there...
