Abstract
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 and a method of selecting transformed plants are also provided.
Claims10
A method of selecting plants, plant tissue or plant cells transformed with a transgene of interest from non-transformed plants, comprising the steps of:
- (a) transforming plants, plant tissue or plant cells with a transgene of interest capable of being expressed by the plants, plant tissue or plant cells, and a gene encoding an altered protox resistant to a protox inhibitor;
- (b) transferring the plants, plant tissue or plant cells to a medium comprising the protox inhibitor;
- and
- (c) selecting the plants, plant tissue or plant cells which survive in the medium and are transformed with the transgene of interest.
