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.
