Patent number: 6441275Abstract: Methods for increasing resistance in plants to pathogens by the expression of a hydrogen peroxide/reactive oxygen species producing enzyme or an oxalate degrading enzyme. The present invention relates to a method of producing a pathogen resistant hybrid plant by crossing the appropriate transgenic expressing a hydrogen peroxide/reactive oxygen species producing enzyme or an oxalate degrading enzyme with pathogen tolerant lines or inbreds obtained through conventional genetic manipulations, or by transformation of tolerant plants or plant tissues with a hydrogen peroxide/reactive oxygen species producing gene or by altering the expression of an endogenase hydrogen peroxide/reactive oxygen species producing gene. The synergistic effect of expression of a hydrogen peroxide/reactive oxygen species producing enzyme or an oxalate degrading enzyme in a tolerant background gives significant and unexpectedly high resistance to the pathogens.Type: GrantFiled: March 14, 2000Date of Patent: August 27, 2002Assignee: Pioneer Hi-Bred International, Inc.Inventors: Dennis L. Bidney, David G. Charne, Glenn S. Cole, Mark K. Mancl, Igor Falak, Katherine A. P. Nazarian, Christopher J. Scelonge

Patent number: 6323392Abstract: An improved route is provided for producing seeds capable of forming a Brassica napus F1 hybrid via plant breeding wherein the vegetable oil of the seeds exhibits a highly elevated oleic acid (C18:1) content of at least 80 percent by weight (e.g. 80 to 86 percent by weight) and a reduced linolenic acid (C18:3) content of no more than 3 percent by weight (e.g. 1 to 3 percent by weight) based upon the total fatty acid content. The female parent plant (i.e., the seed parent) possesses a homozygous modified FAD-2 gene pair for elevated oleic acid production solely in either the A-genome or the C-genome, and the male parent (i.e, the pollen parent) possesses a homozygous modified FAD-2 gene pair for highly elevated oleic acid production in both the A-genome and the C-genome. Both parent plants also include at least one homozygous modified FAD-3 gene pair for reduced linolenic acid production.Type: GrantFiled: March 1, 1999Date of Patent: November 27, 2001Assignee: Pioneer Hi-Bred International, Inc.Inventor: David G.
