Patent number: 8946507Abstract: A method of producing male or female sterile plants comprising the steps of transforming plant material with a polynucleotide which encodes at least one enzyme which reacts with a non-phytotoxic substance to produce a phytotoxic one, and regenerating the thus transformed material into a plant, wherein the said non-phytotoxic substance is applied to the plant up to the time of male or female gamete formation and/or maturation, so that the non-phytotoxic substance provides for the production of a phytotoxic one which selectively prevents the formation of or otherwise renders the said gametes non-functional, wherein the enzyme is expressed preferentially in either male or female reproductive structures, characterised in that (i) the non-phytotoxic substance is D-phosphinothricin and (ii) the enzyme is a D-amino acid oxidase.Type: GrantFiled: June 21, 2010Date of Patent: February 3, 2015Assignee: Syngenta LimitedInventors: Timothy Robert Hawkes, Glynn Mitchell, Stephen Thomas Hadfield, Paul Anthony Thompson, Russell Viner, Yan Zhang

Publication number: 20090229006Abstract: A polynucleotide is provided, comprising at least a first region encoding a first protein capable of conferring on a plant, or tissue comprising it, resistance or tolerance to a first herbicide, and a second region encoding a second protein likewise capable of conferring resistance to a second herbicide, with the provisos (i) that the polynucleotide does not encode a fusion protein comprising only a 5-enol-pyruvyl-3-phosphoshikimate synthetase (EPSPS) and a glutathione S transferase (GST); (ii) that the polynucleotide does not comprise only regions encoding superoxide dismutase (SOD) and glutathione S transferase (GST); and (iii) that the polynucleotide does not comprise only regions encoding GST and phosphinothricin acetyl transferase (PAT).Type: ApplicationFiled: June 19, 2006Publication date: September 10, 2009Inventors: Ian Jepson, Paul Graham Thomas, Paul Anthony Thompson, Timothy Robert Hawkes, Mary Elizabeth Knight
