  • Publication number: 20230407417
    Abstract: Compositions and methods are provided for genome modification of a target sequence in the genome of a plant or plant cell, without incorporating a selectable transgene marker. The methods and compositions employ a guide polynucleotide/Cas endonuclease system to provide an effective system for modifying or altering target sites within the genome of a plant, plant cell or seed, without incorporating a selectable transgene marker. Once a genomic target site is identified, a variety of methods can be employed to further modify the target sites such that they contain a variety of polynucleotides of interest. Breeding methods and methods for selecting plants utilizing a guide polynucleotide/Cas endonuclease system are also disclosed. Compositions and methods are also provided for editing a nucleotide sequence in the genome of a cell, without incorporating a selectable transgene marker.

  • Patent number: 11713490
    Abstract: A method for identifying a quantitative trait locus associated with desirable nutritional traits in canola includes: analyzing a population of canola plants or germplasm for desirable nutritional traits; determining the genotype of the canola plants or germplasm using at least one marker selected from the group consisting of SEQ ID NO:1 through SEQ ID NO:111; mapping the canola plants or germplasm for the presence of a quantitative trait locus (QTL) associated with the markers; and associating the QTL with the desirable nutritional trait. An isolated and/or recombinant nucleic acid includes a sequence associated with a quantitative trait locus (QTL), wherein the QTL is associated with a desirable nutritional trait in a canola plant or germplasm and wherein the QTL is further associated with at least one marker selected from the group consisting of SEQ ID NO:1 through SEQ ID NO:111.
