Abstract

The present invention provides novel DNA sequences isolated from soybean, wheat, cotton, sugar beet, rape, rice, sorghum, and sugar cane that coding for enzymes having protoporphyrinogen oxidase (protox) activity. In addition, the present invention teaches modified forms of protox enzymes that are herbicide tolerant. Plants expressing herbicide tolerant protox enzymes taught herein are also provided. These plants may be engineered for resistance to protox inhibitors via mutation of the native protox gene to a resistant form or they may be transformed with a gene encoding an inhibitor-resistant from of a plant protox enzyme.
