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. A method for controlling weeds using plants having altered protox activity which confers tolerance to herbicides is described.
Claims6
A method for controlling the growth of undesired vegetation which comprises applying to a population of plants or plant seeds having altered protoporphyrinogen oxidase (protox) activity an effective amount of a protox-inhibiting herbicide, wherein said altered protox activity confers upon said plants or plant seeds tolerance to a herbicide in amounts which inhibit naturally occurring protox activity.
