Publication number: 20230407417Abstract: 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.Type: ApplicationFiled: June 29, 2023Publication date: December 21, 2023Applicant: Corteva Agriscience LLCInventors: ZOE CHRISTINA EHLERT, JOSHUA A. FLOOK, DANIEL GARCIA, DONNA CAROLYNN KNIEVEL, CHERIE OCHSENFELD, THOMAS G. PATTERSON, RYAN PREUSS, SYED MASOOD RIZVI, VAN L. RIPLEY, STEVE ROUNSLEY, SHUNXUE TANG, MUHAMMAD TAHIR, MICHELLE WIGGINS

Patent number: 11713490Abstract: 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.Type: GrantFiled: October 6, 2020Date of Patent: August 1, 2023Assignee: CORTEVA AGRISCIENCE LLCInventors: Shunxue Tang, Van L. Ripley, Thomas G. Patterson, Michelle Wiggins, Joshua A. Flook, Cherie Ochsenfeld, Daniel Garcia, Syed Masood Rizvi, Ryan Preuss, Donna Carolynn Knievel, Zoe Christina Ehlert, Steve Rounsley, Muhammad Tahir

Publication number: 20220000053Abstract: The invention relates to improved Brassica species, including Brassica juncea, improved oil and meal from Brassica juncea, methods for generation of such improved Brassica species, and methods for selection of Brassica lines. Further embodiments relate to seeds of Brassica juncea comprising an endogenous oil having increased oleic acid content and decreased linolenic acid content relative to presently existing commercial cultivars of Brassica juncea, seeds of Brassica juncea having traits for increased oleic acid content and decreased linolenic acid content in seed oil stably incorporated therein, and one or more generations of progeny plants produced from said seeds.Type: ApplicationFiled: May 10, 2021Publication date: January 6, 2022Inventors: Van Leonard Ripley, Steven A. Thompson, Zoë Christina Ehlert
