The present invention provides novel plants that are resistant not only to 2,4-D but also to pyridyloxyacetic acid herbicides. The invention also includes plants that produce one or more enzymes of the invention “stacked” together with one or more other herbicide resistance genes. The present invention allows new combinations of herbicides to be used in new forms. Furthermore, the present invention provides a novel method for preventing and controlling the development of weed lines that are resistant to one or more herbicides such as glyphosate. A preferred enzyme and gene for use according to the present invention is referred to herein as AAD-13 (aryloxyalkanoate dioxygenase). This very new discovery is based on the potential for significant herbicide-tolerant crop traits and selectable markers. |
