Patent number: 6808904Abstract: The present invention provides novel DNA sequences coding for protoporphyrinogen oxidase (protox) enzymes from soybean, wheat, cotton, sugar beet, oilseed rape, rice, sorghum, and sugar cane. In addition, the present invention teaches modified forms of protox enzymes that are herbicide tolerant. Plants expressing herbicide tolerant protox enzymes taught herein are also provided. These plants may be engineered for resistance to protox inhibitors via mutation of the native protox gene to a resistant form or they may be transformed with a gene encoding an herbicide tolerant form of a plant protox enzyme. The present invention further provides shuffled DNA molecules encoding protox enzymes having enhanced tolerance to a herbicide that inhibits the protox activity encoded by a template DNA molecule from which the shuffled DNA molecule is derived.Type: GrantFiled: December 5, 2000Date of Patent: October 26, 2004Assignee: Syngenta Participations AGInventors: Eric R. Ward, Sandra L. Volrath, Marie A. Johnson, Sharon L. Potter

Publication number: 20020197696Abstract: The invention relates to genes isolated from Arabidopsis that code for proteins essential for seedling growth. The invention also includes the methods of using these proteins to discover new herbicides, based on the essentiality of the genes for normal growth and development. The invention can also be used in a screening assay to identify inhibitors that are potential herbicides. The invention is also applied to the development of herbicide tolerant plants, plant tissues, plant seeds, and plant cells.Type: ApplicationFiled: January 14, 2002Publication date: December 26, 2002Inventors: Joshua Z. Levin, Gregory J. Budziszewski, Sharon L. Potter, Lynette M. Wegrich

Patent number: 5981844Abstract: Novel plant proteins (SAFPs) which synergize the activity of antifungal antibiotics are identified. SAFPs are demonstrated to synergize antifungal antibiotics, such as nikkomycins, polyoxins and amphotericins. SAFPs alone also display antifungal activity against several species of fungi, including strains of Candida, Trichoderma, Neurospora and strains of the plant pathogens Fusarium, Rhizoctonia and Chaetomium. Synergistic antifungal compositions containing SAFP and antifungal antibiotics are provided. In particular, synergistic compositions of corn-SAFP (zeamatin), sorghum-SAFP (sormatin) or oat-SAFP (avematin) and nikkomycin are found to be effective as antifungal compositions, especially against the opportunistic human pathogen Candida albicans. Method for employing SAFPs and synergistic compositions containing them for the inhibition of fungi are provided. In addition, a method for purifying SAFP from grain meal is provided.Type: GrantFiled: December 19, 1997Date of Patent: November 9, 1999Assignees: Novartis Finance Corporation, University Research CorporationInventors: Walden K. Roberts, Claude P. Selitrennikoff, Bridget E. Laue, Sharon L. Potter
