  • 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.

  • Publication number: 20230197189
    Abstract: Systems and methods for organism genotyping and using genomic data for genotype imputation are disclosed. The system can maintain first genetic sequence information of a sire and second genetic sequence information for a dam, the first and second genetic sequence information indicating one or more single nucleotide polymorphisms (SNPs) of interest. The system can sequence, based on a skim sequencing technique, a sample of genetic information of a progeny of the sire and the dam. The system can identify informative variants based on the first genetic sequence information and the second genetic sequence information. The system can identify informative reads in the sequence of the progeny based on the informative variants. The system can construct a genotype of the progeny based on the informative reads and the one or more SNPs of interest in the first and second genetic sequence information.

  • Publication number: 20220119865
    Abstract: Methods and systems for processing semen samples from straws for determining genetic identity, testing the purity of the sample, detecting errors or contamination, calculating an amount of contamination, and determining the identity of the contaminant. The methods herein can detect low levels of contamination, such as contamination of about 0.5%, 1%, 2%, etc.

  • Publication number: 20220017975
    Abstract: This disclosure concerns methods and compositions for identifying canola plants that have a low fiber content trait. Some embodiments concern a chromosomal interval and a quantitative trait locus associated with low fiber content in canola plants or germplasm. Some embodiments concern molecular markers to identify, select, and/or construct low fiber content canola plants and germplasm, or to identify and counter-select plants with relatively higher fiber content. This disclosure also concerns canola plants comprising a low fiber content trait that are generated by methods utilizing at least one marker described herein.
