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.

Abstract: This invention relates to an isolated nucleic acid fragment encoding an oxidosqualene cyclase. The invention also relates to the construction of a chimeric gene encoding all or a portion of the isolated polynucleotides of the invention, in sense or antisense orientation, operably linked to a suitable regulatory sequence.

Abstract: This invention relates to an isolated nucleic acid fragment encoding a sulfate assimilation protein. The invention also relates to the construction of a chimeric gene encoding all or a portion of the sulfate assimilation protein, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the sulfate assimilation protein in a transformed host cell.

Abstract: This invention relates to the use of recombinant DNA fragments encoding at least a portion of an oxidosqualene cyclase to lower the level of a triterpene in plants and seeds. Plants, plant parts, and seeds with a low level of triterpene are part of the invention. Included are food and feed products obtained from the plants, plant parts, or seeds or the invention.

Abstract: This invention related to an isolated nucleic acid fragment encoding a tryptophan biosynthetic enzyme. This invention also related to the construction of a Chimeric gene encoding all or a portion of the tryptophan biosynthetic enzyme, in sense or antisense orientation, wherein expression of the Chimeric gene results in the production of altered levels of the tryptophan biosynthetic enzyme in a transformed host cell. The tryptophan biosynthetic enzymes include anthranilate phosphoribosyltransferase (E.C. 2.4.2.18) from corn (Zea mays), soybean (Glycine max) and wheat (Triticum aestivum); indole-3-glycerol phosphate synthase (E.C. 4.1.1.48) from corn (Zea mays), rice (Oryza sativa), soybean (Glycine max), and wheat (Triticum aestivum); and phosphoribosylanthranilate isomerase (E.C. 5.3.1.24) from corn (Zea mays), rice (Oryza sativa), (and wheat (Triticum aestivum).
