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: The invention relates to plants with increased levels of triterpene saponins. The plant may have an increased activity of at least one oxidosqualene cyclase that catalyzes the cyclization of 2,3-oxidosqualene to form a cyclyzed triterpene. The plant may be transformed with at least one recombinant DNA molecule comprising a promoter operably linked to at least one polynucleotide encoding an oxidosqualene cyclase, said recombinant DNA molecule sufficient to increase production of a triterpene saponin; or any progeny of said plant, wherein said progeny comprise said recombinant DNA molecule.

Abstract: Recombinant constructs for reducing flavonol levels in a flavonol-producing plants are described. Such constructs comprise a promoter operably linked to a stem-loop structure wherein a nucleic acid sequence of at least 200 nucleotides and having at least 75% sequence identity to SEQ ID NO:4 forms part of loop part of the structure. Methods for reducing flavonol levels are also described.
