abstract：:An R plasmid, R100-1, was mapped previously (Yoshikawa, 1974) by transduction from an integratively suppressed Hfr strain to a recipient with a mutation in gene dnaA. By this method various types of transductants of plasmid R100-1 that exist autonomously or in the integrated state were obtained. Seventy-one such trans...
