[Mapping chromosomes of Erwinia carotovora subsp. Atroseptica 3-2].

Two Hfr-like donor strains of bacteria Erwinia carotovora subsp. atroseptica (Eca) 3-2 were developed by integration into the chromosome of the conjugative plasmid R471a via homology with transposon Tn9. Using these and two donor strains created earlier, we constructed the genetic map of a fragment of the chromosome of strain Eca 3-2. The location of 14 loci is shown in this map.
