Latest Patents

Hadfield's latest patents focus on methods for selectively producing male or female sterile plants. One of his patents describes a method that involves transforming plant material with a polynucleotide encoding an enzyme that reacts with a non-phytotoxic substance to produce a phytotoxic one. This method allows for the regeneration of transformed material into a plant, where the non-phytotoxic substance is applied until the formation and maturation of male or female gametes. The enzyme is expressed preferentially in either male or female reproductive structures, utilizing D-phosphinothricin as the non-phytotoxic substance and a D-amino acid oxidase as the enzyme. Another patent outlines a similar method, but with a D-alpha amino acid as the non-phytotoxic substance.
