Abstract
System, including methods and compositions, for making and using transgenic plants capable of metabolizing phosphite to reduce competition from weeds. The plants may be transgenically modified to express a phosphite dehydrogenase enzyme capable of catalyzing oxidation of phosphite to phosphate and grown in the presence of sufficient phosphite to selectively promote growth of the plant relative to weeds near the plant.
Claims15
A method of controlling weeds, the method comprising:
- growing a plurality of plants in the presence of phosphite, wherein at least one plant expresses a phosphite dehydrogenase enzyme sharing at least 95% identity to SEQ ID NO:1 and at least one plant does not express said enzyme;
- wherein the plurality of plants are grown in the presence of sufficient phosphite to selectively promote the growth of the at least one plant expressing the enzyme resulting in its increased growth relative to the at least one plant lacking said enzyme.
Dependencies are inferred from the claim text.
