The invention provides isolated pyruvate dehydrogenase kinase nucleic acids and their encoded polypeptides. The present invention provides methods and compositions relating to altering pyruvate dehydrogenase kinase levels in plants. The invention further provides recombinant expression cassettes, host cells, transgenic plants, and antibody compositions.

Polynucleotides encoding proteins involved in plant metabolism

This invention relates to an isolated nucleic acid fragment encoding a farnesyltransferase subunit. The invention also relates to the construction of a chimeric gene encoding all or a portion of the farnesyltransferase subunit, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the farnesyltransferase subunit in a transformed host cell.

Plant farnesyltransferases

This invention relates to an isolated nucleic acid fragment encoding a disease resistance factor. The invention also relates to the construction of a chimeric gene encoding all or a substantial portion of the disease resistance factor, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the disease resistance factor in a transformed host cell.

Disease resistance factors

The preparation and use of nucleic acid fragments encoding fatty acid desaturase enzymes are described. The invention permits alteration of plant lipid composition. Chimeric genes incorporating such nucleic acid fragments with suitable regulatory sequences may be used to create transgenic plants with altered levels of unsaturated fatty acids.

Methods for decreasing linolenic acid content in seeds from transgenic plants containing a mutant delta 15 desaturase

This invention relates to an isolated nucleic acid fragment encoding a reproduction protein. The invention also relates to the construction of a chimeric gene encoding all or a portion of the reproduction protein, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the reproduction protein in a transformed host cell. The invention also provides isolated transcriptional regulatory elements and polynucleotides associated therewith.

Plant reproduction polynucleotides and methods of use

Brassicaceae plants are disclosed that contain a mutation in a delta-12 fatty acid desaturase gene and that have altered fatty acid composition in seeds. In one embodiment, a Brassicaceae plant contains a mutation in a region having the conserved motif His-Xaa-Xaa-Xaa-His, found in delta-12 and delta-15 fatty acid desaturases. A preferred motif has the sequence His-Glu-Cys-Gly-His. A preferred mutation in this motif has the amino acid sequence His-Lys-Cys-Gly-His.

Plants having mutant delta-12 desaturase sequences that confer altered fatty acid profiles

This invention relates to plant defensin polypeptides, nucleic acids encoding them, and methods of use thereof. The invention also relates to a chimeric protein containing all or a portion of the plant defensin.

Plant defensin polynucleotides and methods of use thereof

This invention relates to an isolated nucleic acid fragment encoding an Mlo homolog. The invention also relates to the construction of a chimeric gene encoding all or a portion of the Mlo homolog, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the Mlo homolog in a transformed host cell.

Plant disease resistance genes

Plants are disclosed that contain a mutation in a delta-12 or delta-15 fatty acid desaturase gene. Preferred plants are rapeseed and sunflower plants. Plants carrying such mutant genes have altered fatty acid composition in seeds. In one embodiment, a plant contains a mutation in a region having the conserved motif His-Xaa-Xaa-His, found in delta-12 and delta-15 fatty acid desaturases. A preferred motif has the sequence His-Glu-Cys-Gly-His. A preferred mutation in this motif has the amino acid sequence His-Lys-Cys-Gly-His. Nucleic acid fragments are disclosed that comprise a sequence of at least 20 nucleotides from a mutant delta-12 or delta-15 fatty acid desaturase gene.

Brassica or helianthus plants having mutant delta-12 or delta-15 sequences

The preparation and use of nucleic acid fragments encoding fatty acid desaturase enzymes are described. The invention permits alteration of plant lipid composition. Chimeric genes incorporating mutant delta-12 fatty acid desaturase nucleic acid fragments with suitable regulatory sequences may be used to create transgenic plants with altered levels of unsaturated fatty acids.

Methods for increasing oleic acid content in seeds from transgenic plants containing a mutant delta 12 desaturase
