    摘要: Seeds, plants and oils are provided having high oleic acid; low linoleic acid; and low linoleic acid plus linolenic acid; and advantageous functional or nutritional properties. 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-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 mutant delta-12 or delta-15 fatty acid desaturase gene sequence.

    摘要: This invention relates to isolated nucleic acid fragments encondign defense response proteins. The invention also relates to the construction of chimeric genes enconding all or a substantial portion of the defense response proteins, in sense or antisense orientation, wherein expression of the chimeric genes results in production of altered levels of the defense response proteins in a transformed host cell. This invention further relates to a method of introgressing disease resistance loci into rice germplasm.
