Generation of plants with altered oil, protein, or fiber content
View Patent ↗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 HIO nucleic acid. The invention is further directed to methods of generating plants with an improved oil quantity phenotype or improved meal quality phenotype.
1. A method of generating a plant having an increased oil content, comprising:
identifying a plant that has an allele in its ortholog of the A. thaliana HIO2084A gene, where the wild-type A. thaliana HIO2084A gene has the nucleic acid set forth as SEQ ID NO: 17, which allele results in increased oil content compared to plants lacking the allele; and
generating progeny of said identified plant, wherein the generated progeny inherit the allele and have the high oil phenotype.
2. The method of claim 1 that employs candidate gene/QTL methodology.
3. The method of claim 1 that employs TILLING methodology.
4. 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 HIO2084A gene, where the wild-type A. thaliana HIO2084A gene has the nucleic acid sequence set forth as SEQ ID NO: 17, which allele results in increased meal quality compared to plants lacking the allele; and
generating progeny of said identified plant, wherein the generated progeny inherit the allele and have the increased meal quality,
thereby generating a plant having an improved meal quality phenotype.
5. The method of claim 4 that employs candidate gene/QTL methodology.
6. The method of claim 4 that employs TILLING methodology.
