摘要:
An isolated nucleic acid fragment encoding a chalcone isomerase is disclosed. Also of concern is the synthesis of a recombinant DNA construct encoding all or a portion of the chalcone isomerase, in sense or antisense orientation, wherein expression of the recombinant DNA construct results in production of altered levels of the chalcone isomerase in a transformed host cell.
摘要:
This invention relates to an isolated nucleic acid sequence encoding isoflavone synthase. The invention also relates to the construction of chimeric sequences encoding all or a substantial portion of the enzymes, in sense or antisense orientation, wherein expression of the chimeric sequence results in production of altered levels of the enzyme in a transformed host cell.
摘要:
This invention relates to an isolated nucleic acid fragment encoding a sterol biosynthetic enzyme. The invention also relates to the construction of a chimeric gene encoding all or a portion of the sterol biosynthetic enzyme, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the sterol biosynthetic enzyme in a transformed host cell.
摘要:
This invention relates to isolated nucleic acid fragments encoding all or a substantial portion of maize glutathione-S-transferase (GST) enzymes involved in the detoxification of xenobiotic compounds in plants and seeds. The invention also relates to the construction of chimeric genes encoding all or a substantial portion of maize GST enzymes, host cells transformed with those genes and methods of the recombinant production of maize GST enzymes. Methods of constructing transgenic plants having altered levels of GST enzymes and screens for identifying maize GST enzyme substrates and maize GST enzyme inhibitor, are also provided.
摘要:
Methods and compositions are provided which employ a silencing element that, when ingested by a pest, such as a Pentatomidae plant pest or a N. viridula, Acrosternum hilare, Piezodorus guildini, and/or Halymorpha halys plant pest, decrease the expression of a target sequence in the pest. In specific embodiments, the decrease in expression of the target sequence controls the pest and thereby the methods and compositions are capable of limiting damage to a plant. The present invention provides various target polynucleotides set forth in any one of SEQ ID NOS: 1-292 or 302-304 or active variants and fragments thereof, wherein a decrease in expression of one or more the sequences in the target pest controls the pest (i.e., has insecticidal activity). Further provided are silencing elements which when ingested by the pest decrease the level of the target polypeptide and thereby control the pest. In specific embodiment, the pest is Pentatomidae. Plants, plant part, bacteria and other host cells comprising the silencing elements or an active variant or fragment thereof of the invention are also provided.
摘要:
Compositions and methods relating to the use of sulfonylurea-responsive repressors are provided. Compositions include polypeptides that specifically bind to an operator, wherein the specific binding is regulated by a sulfonylurea compound. Compositions also include polynucleotides encoding the polypeptides as well as constructs, vectors, prokaryotic and eukaryotic cells, and eukaryotic organisms including plants and seeds comprising the polynucleotide, and/or produced by the methods. Also provided are methods to provide a sulfonylurea-responsive repressor to a cell or organism, and to regulate expression of a polynucleotide of interest in a cell or organism, including a plant or plant cell.
摘要:
The present invention relates to Δ9 elongases, which have the ability to convert linoleic acid [18:2, LA] to eicosadienoic acid [20:2, EDA]. Isolated nucleic acid fragments and recombinant constructs comprising such fragments encoding Δ9 elongase along with methods of making long-chain polyunsaturated fatty acids (PUFAs) using these Δ9 elongases in plants and oleaginous yeast are disclosed.
