  • Phosphinothricin-resistance gene, and its use
    Patent number: 5879903
    Abstract: Selection of Streptomyces viridochromogenes DSM 4112 for resistance to phosphinothricyl-alanyl-alanine (PTT) results in PTT-resistance selectants. The DNA fragment which carries the phosphinothricin(PTC)-resistance gene is obtained from the total DNA of these selectants by cutting with BamHI, cloning of a fragment 4.0 kb in size, and selection for PTT resistance. This gene is suitable for the production of PTC-resistant plants, and as a resistance marker and for the selective N-acetylation of the L-form of racemic PTC.
    Type: Grant
    Filed: June 7, 1995
    Date of Patent: March 9, 1999
    Assignee: Hoechst Aktiengesellschaft
    Inventors: Eckhard Strauch, Wolfgang Wohlleben, Walter Arnold, Renate Alijah, Alfred Puhler, Gerhard Wohner, Rudiger Marquardt, Susanne Grabley, Dieter Brauer, Klaus Bartsch

  • Phosphinothricin-resistance gene, and its use
    Patent number: 5276268
    Abstract: The phosphinothricin (PTC)-resistance gene isolated from the genome of Streptomyces viridochromogenes DSM 40736 is, after adaptation to the codon usage in plants, synthesized and incorporated into gene structures which make plants resistant to PTC after expression therein.
