GENETIC DETERMINANTS OF COLICIN PRODUCTION, PRINCIPALLY THEIR RELATION WITH BAOTERICPHAGES AND WITH THE F AGENT OF FERTILITY

摘要

Many recombinants obtained in crosses of wild strain E.coli K260, carrying V and B colicinogenic factors linked to an F agent, with strains, carrying a deletion in the try region, are partial diploids, heterozygous for the try marker. They have been analyzed in conjugation and transduction experiments.
