Gene Technology

The gene multiplication method with plasmid vectors has been applied to the breeding of amino acid producers. When a plasmid vector that can multiply within an amino acid producer is joined enzymatically to a DNA fragment carrying the genetic information from other strains of the same microorganism or other microorganisms, the resultant recombinant DNA is transferred to the amino acid producer to introduce new markers of the donor microorganisms. A plasmid such as pCGll has sites sensitive to various restriction endonucleases and is easily joined to a DNA fragment prepared by digestion with corresponding restriction enzymes. Moreover, because it has the genes determining streptomycin resistance, it is easy to select strains with plasmids carrying these antibiotic resistance markers (40).
