MODULATION OF ENZYMATIC ACTIVITY OF PROTOPORPHYRINOGEN OXIDASE IN EUCARYOTES

摘要

FIELD: genetic engineering, biochemistry, enzymes, agriculture. SUBSTANCE: incorporation of DNA molecule encoding protoporphyrinogen oxidase (protox) into plant cells confers resistance of latter to herbicide. DNA sequences can be used as probes for testing chemical compounds also with respect to their ability to inhibit activity of protox, for identification of modified protox and for selection of plants showing resistance to herbicides also. Invention can be used in plants selection. EFFECT: valuable properties of enzyme. 45 cl, 2 tbl
