Abstract
Virus genes, for example coat protein genes, which bring about a reduction in the signs of infection by the corresponding virus or bring about virus resistance can be combined with herbicide-resistance genes for the transformation of plants. A combination of this type facilitates the selection of the transgenic plants. In addition, in practical field cultivation, the vitality of the plants is increased by the virus tolerance, and an improved plant protection is possible owing to the herbicide-resistance gene.
Claims19
An isolated DNA molecule consisting of a nucleotide sequence coding region for a phosphinothricin acetyl transferase protein which confers phosphinothricin resistance and a nucleotide sequence coding region for a virus coat protein which confers virus resistance.
A transformed plant cell containing and expressing an isolated DNA molecule consisting of a nucleotide sequence coding region for a phosphinothricin acetyl transferase protein which confers phosphinothricin resistance and, an isolated DNA molecule consisting of a nucleotide sequence coding region for a virus coat protein which confers virus resistance.
A method for improving growth of a plant comprising:
- transforming plant cells so that the cells contain an isolated DNA molecule consisting of a nucleotide sequence coding region for a phosphinothricin acetyl transferase protein which confers phosphinothricin resistance and, an isolated DNA molecule consisting of a nucleotide sequence coding region for a virus coat protein which confers virus resistance;
- selecting transformed cells;
- regenerating plants from the cells;
- and treating the regenerated plants with a phosphinothricin herbicide.
