Generalized transduction in Rhizobium meliloti
Abstract
The phage 11 of R. meliloti performs generalized transduction. This was confirmed by the variety of single markers transferred and by separating transducing particles containing BUdR-labelled bacterial DNA. The transduction frequencies depended on the marker. Linked alleles were mapped by cotransduction on fragments of bacterial DNA equal in size to the phage DNA. With crosses between antibiotic resistancy and auxotrophic markers a partial map was constructed with str, cml, pur-19, and leu-44 sites. With a few multi-auxotrophic mutants linkage data of conjugation were compared with the linkage by cotransduction.
