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.

Abstract: A plant cultivation system, including methods, apparatus, plants, and compositions, for utilizing phosphite as a nutrient to support growth of a transgenic plant and as a control agent for unwanted organisms, such as weeds and/or algae, among others. In an exemplary method, an effective amount of phosphite is applied to a substrate, and/or to foliage above the substrate, to enhance growth of a transgenic plant and/or to act as a weed-control agent that kills weeds and/or directly suppresses growth of weeds near the transgenic plant. In another exemplary method, soil is tested for a content of phosphate, and an effective amount of phosphite for supporting growth of a transgenic plant and controlling weeds is selected and applied based on the content of phosphate. In yet another exemplary method, phosphite is used to control algae in a hydroponic system.
