The present invention provides novel eukaryotic DNA sequences coding for native protoporphyrinogen oxidase (protox) or modified forms of the enzyme which are herbicide tolerant. Plants having altered protox activity which confers tolerance to herbicides are also provided. These plants are engineered for resistance to protox inhibitors via mutation of the native protox gene to a resistant form or they are transformed with modified eukaryotic or prokaryotic protox coding sequences or wild type prokaryotic protox sequences which are herbicide tolerant. Plant genes encoding wild-type and altered protox, purified plant protox, methods of isolating protox from plants, and methods of using protox-encoding genes are also disclosed.
A plant, plant tissue or plant seed having altered protoporphyrinogen oxidase (protox) activity, wherein said altered protox activity is conferred by expression of a DNA molecule encoding a herbicide tolerant protox enzyme, wherein said altered protox activity confers upon said plant tolerance to a herbicide in amounts which inhibit naturally occurring protox activity.
A plant, plant tissue or plant seed comprising a chimeric DNA molecule comprising a promoter operably linked to a DNA molecule encoding a protox enzyme, wherein said DNA molecule encoding a protox enzyme confers upon said plant, plant tissue or plant seed tolerance to an inhibitor of naturally occurring protox activity.
A method of producing a plant, plant tissue, or plant seed, that is tolerant to a herbicidal compound in an amount that naturally inhibits plant growth, comprising the steps of:
