This invention relates generally to the detection of genetic differences among soybeans. More particularly, the invention relates to soybean quantitative trait loci (QTL) for tolerance or sensitivity to HPPD-inhibitor herbicides, such as mesotrione and isoxazole herbicides, to soybean plants possessing these QTLs, which map to a novel chromosomal region, and to genetic markers that are indicative of phenotypes associated with tolerance, improved tolerance, susceptibility, or increased susceptibility. Methods and compositions for use of these markers in genotyping of soybean and selection are also disclosed, as are methods and compositions for use of these markers in selection and use of herbicides for weed control. Also disclosed are isolated polynucleotides and polypeptides relating to such tolerance or sensitivity and methods of introgres sing such tolerance into a plant by breeding or transgenically or by a combination thereof. Plant cells, plants, and seeds produced are also provided.

HPPD-inhibitor herbicide tolerance

This invention relates generally to the detection of genetic differences among soybeans. More particularly, the invention relates to soybean quantitative trait loci (QTL) for tolerance or sensitivity to HPPD-inhibitor herbicides, such as mesotrione and isoxazole herbicides, to soybean plants possessing these QTLs, which map to a novel chromosomal region, and to genetic markers that are indicative of phenotypes associated with tolerance, improved tolerance, susceptibility, or increased susceptibility. Methods and compositions for use of these markers in genotyping of soybean and selection are also disclosed, as are methods and compositions for use of these markers in selection and use of herbicides for weed control. Also disclosed are isolated polynucleotides and polypeptides relating to such tolerance or sensitivity and methods of introgressing such tolerance into a plant by breeding or transgenically or by a combination thereof. Plant cells, plants, and seeds produced are also provided.

This invention relates generally to the detection of genetic differences among soybeans. More particularly, the invention relates to soybean quantitative trait loci (QTL) for tolerance to protoporphyrinogen oxidase inhibitors, to soybean plants possessing these QTLs, which map to a novel chromosomal region, and to genetic markers that are indicative of phenotypes associated with protoporphyrinogen oxidase inhibitor tolerance. Methods and compositions for use of these markers in genotyping of soybean and selection are also disclosed.

Molecular markers linked to PPO inhibitor tolerance in soybeans

Compositions and methods for identifying soybean plants with reduced levels of saturated fatty acids are provided. Methods of making soybean plants with reduced levels of saturated fatty acids, e.g., through introgression of desired saturated fatty acid marker alleles and/or by transgenic production methods, as well as plants or germplasm made by these methods, are provided. Kits for selecting plants with reduced levels of saturated fatty acids are also provided.

Soybean sequences associated with the FAP3 locus

The present invention provides compositions and methods for regulating expression of isolated nucleotide sequences in a plant. The compositions are novel nucleic acid sequences for seed-preferred regulatory sequences. Methods for expressing an isolated nucleotide sequence in a plant using the regulatory sequences are also provided. The methods comprise transforming a plant cell to contain an isolated nucleotide sequence operably linked to the seed-preferred regulatory sequences of the present invention and regenerating a stably transformed plant from the transformed plant cell.
