Summary for Patent: 7,750,210

Title:	Compositions with increased phytosterol levels obtained from plants with decreased triterpene saponin levels
Abstract:	This invention is in the field of plant molecular biology. More specifically, this invention pertains to compositions having increased levels of at least one phytosterol, said compositions being obtained from plants or plant parts, and methods thereof. The plants may have decreased levels of triterpene saponins. The plants or plant parts may comprise at least one recombinant DNA molecule comprising a promoter operably linked to at least a portion of at least one polynucleotide from at least one oxidosqualene cyclase gene, said recombinant DNA molecule sufficient to increase the production of at least one phytosterol; or any progeny of said plant, wherein said progeny comprise said recombinant DNA molecule. Compositions, oils, as well as food and feed products obtained from or prepared with said compositions are also part of the invention.
Inventor(s):	McGonigle; Brian (Wilmington, DE), Maxwell; Carl A. (Elkton, MD), Hession; Aideen Oonagh (Wilmington, DE)
Assignee:	E. I. du Pont de Nemours and Company (Wilmington, DE)
Application Number:	11/593,880
Patent Claims:	1. A method of producing a composition containing increased level of one or more phytosterols comprising processing a plant or portion thereof, wherein said plant comprises at least one recombinant DNA molecule, wherein expression of said recombinant DNA molecule is sufficient to decrease activity of a .beta.-amyrin synthase and to increase production of a phytosterol as compared to a plant not comprising said recombinant DNA molecule, wherein the composition contains at least 1.5 times by weight as much of a phytosterol as a composition prepared from a plant not expressing said recombinant DNA molecule. 2. A method of producing a phytosterol-containing extract, wherein the extract contains an increased level of at least one phytosterol comprising: a) obtaining oil by processing a plant or portion thereof wherein said plant comprises at least one recombinant DNA molecule, wherein expression of said recombinant DNA molecule is sufficient to decrease the activity of a .beta.-amyrin synthase and to increase production of a phytosterol as compared to a plant not comprising said recombinant DNA molecule; and b) extracting the phytosterol-containing extract from the oil of (a), wherein the extract contains at least 1.5 times by weight as much of a phytosterol as an extract prepared from a plant not expressing said recombinant DNA molecule. 3. A recombinant DNA molecule comprising: a) a portion of a .beta.-amyrin synthase gene b) an intron, and c) an inverted repeat of a), wherein the intron is an isoflavone synthase intron. 4. A recombinant DNA molecule comprising: a) a portion of a .beta.-amyrin synthase gene b) an intron, and c) an inverted repeat of a), wherein the recombinant DNA molecule comprises a nucleotide sequence of SEQ ID NO:32.
