Publication number: 20200190494Abstract: Compositions and methods are provided for genome modification of a target sequence in the genome of a cell, using a novel Cas endonuclease. The methods and compositions employ a guide polynucleotide/endonuclease system to provide an effective system for modifying or altering target sequences within the genome of a cell or organism. Also provided are novel effectors and endonuclease systems and elements comprising such systems, such as guide polynucleotide/endonuclease systems comprising an endonuclease. Compositions and methods are also provided for guide polynucleotide/endonuclease systems comprising at least one endonuclease, optionally covalently or non-covalently linked to, or assembled with, at least one additional protein subunit, and for compositions and methods for direct delivery of endonucleases as ribonucleotide proteins.Type: ApplicationFiled: December 13, 2019Publication date: June 18, 2020Applicant: PIONEER HI-BRED INTERNATIONAL, INC.Inventors: ZHENGLIN HOU, TAUTVYDAS KARVELIS, VIRGINIJUS SIKSNYS, JOSHUA K YOUNG

Publication number: 20200131529Abstract: Compositions and methods for controlling pests are provided. The methods involve transforming organisms with a nucleic acid sequence encoding an insecticidal protein. In particular, the nucleic acid sequences are useful for preparing plants and microorganisms that possess insecticidal activity. Thus, transformed bacteria, plants, plant cells, plant tissues and seeds are provided. Compositions are insecticidal nucleic acids and proteins of bacterial species. The sequences find use in the construction of expression vectors for subsequent transformation into organisms of interest, as probes for the isolation of other homologous (or partially homologous) genes. The insecticidal proteins find use in controlling, inhibiting growth or killing lepidopteran, coleopteran, dipteran, fungal, hemipteran, and nematode pest populations and for producing compositions with insecticidal activity.Type: ApplicationFiled: January 13, 2020Publication date: April 30, 2020Applicant: PIONEER HI-BRED INTERNATIONAL, INC.Inventors: RUTH CONG, JINGTONG HOU, ZHENGLIN HOU, PHILLIP A PATTEN, TAKASHI YAMAMOTO
