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 the isolation and modification of nucleic acid sequences encoding p-hydroxyphenylpyruvate dioxygenase enzyme from plants. These nucleic acid sequences were used to establish methods of identification of new herbicidal compounds that inhibit the activity of this enzyme, and to prepare new crop plants that are tolerant to the herbicidal action of inhibitors this enzyme. Chimeric genes comprising nucleic acid fragments containing all or part of the nucleic acid sequences encoding p-hydroxyphenylpyruvate dioxygenase may be used to produce active plant p-hydroxyphenylpyruvate dioxygenase enzyme in microorganisms, and to cause the production of modified forms of the enzyme in plants that may render such plants tolerant to inhibitors of the enzyme.
