Abstract
The present invention is directed to plants that display an improved oil quantity phenotype or an improved meal quality phenotype due to altered expression of an IMQ nucleic acid. The invention is further directed to methods of generating plants with an improved oil quantity phenotype or improved meal quality phenotype.
Claims30
A transgenic plant, comprising a plant transformation vector comprising a nucleotide sequence that encodes or is the complement of a sequence that encodes an IMQ polypeptide comprising an amino acid sequence at least 90% identical to the amino acid sequence as set forth in SEQ ID NO:
- 76, whereby the transgenic plant has an improved meal quality phenotype, relative to control plants.
A method of producing an improved meal quality phenotype in a plant, said method comprising:
- a) introducing into progenitor cells of the plant a plant transformation vector comprising a nucleotide sequence that encodes or is the compliment of a sequence that encodes an IMQ polypeptide comprising an amino acid sequence at least 90% identical to the amino acid sequence set forth in SEQ ID NO:
- 76, and
- b) growing the transformed progenitor cells to produce a transgenic plant, wherein the nucleotide sequence is expressed, and the transgenic plant exhibits an improved meal quality phenotype relative to control plants,
- thereby producing the improved meal quality phenotype in the plant.
A method of generating a plant having an improved meal quality phenotype comprising identifying a plant that has an allele in its ortholog of the A. thaliana IMQ gene where the wildtype A. thaliana gene has the nucleic acid sequence set forth as SEQ ID NO:
- 45, which allele results in improved meal quality phenotype, compared to plants lacking the allele, wherein identifying a plant comprises analyzing the sequence of the allele of the ortholog of the IMQ gene in the plant;
- and
- generating progeny of said identified plant, wherein the generated progeny inherit the allele and have the improved meal quality phenotype, thereby generating a plant having an improved meal quality phenotype.
A feed, meal, grain, food, or seed comprising a recombinant polypeptide encoded by a nucleic acid sequence at least 90% identical to the nucleic acid sequence as set forth in SEQ ID NO:
- 75.
A feed, meal, grain, food, or seed comprising a polypeptide comprising an amino acid sequence at least 90% identical to the amino acid sequence as set forth in SEQ ID NO:
- 76.
