Publication number: 20230383306Abstract: The present invention relates to an allele designated alpha-WOLF 26 which confers resistance to at least one Peronospora effusa race, wherein the protein encoded by said allele is a CC-NBS-LRR protein that comprises in its amino acid sequence: a) the motif “MAEIGYSVC” (SEQ ID NO: 1) at its N-terminus; and b) the motif “KWMCLR” (SEQ ID NO: 2); and wherein the LRR domain of the protein has in order of increased preference at least 91%, 91.5%, 92%, 92.5%, 93%, 93.5%, 94%, 94.5%, 95%, 95.5%, 96%, 96.5%, 97%, 97.5%, 98%, 98.5%, 99%, 99.5%, 100% sequence identity to SEQ ID NO: 10. The allele when homozygously present in a spinach plant confers complete resistance to at least Peronospora effusa race Pe: 7, Pe: 10, Pe: 11, Pe: 12, Pe: 13, Pe: 14, Pe: 15, Pe: 16, Pe: 17, and does not confer resistance to downy mildew race Pe: 8 and Pe: 9.Type: ApplicationFiled: April 25, 2023Publication date: November 30, 2023Inventors: Raoul Jacobus Johannes Maria FRIJTERS, Erik DEN BOER

Patent number: 11690339Abstract: The invention relates to a lettuce plant (Lactuca sativa L.) which may comprise a resistance allele which confers a broad spectrum resistance to Bremia lactucae, wherein the resistance allele is located on linkage group 9, and which resistance allele is as found in the genome of plants grown from seeds of which a representative sample was deposited under accession number NCIMB 42141. The invention further provides seeds, progeny, propagation material and food products from the plant.Type: GrantFiled: September 16, 2019Date of Patent: July 4, 2023Assignees: RIJK ZWAAN ZAADTEELT EN ZAADHANDEL B.V., NUNHEMS B.V., VILMORIN & CIEInventors: Marie Jeanette Willemijn Jeuken, Erik Den Boer, Richard Gerardus Franciscus Visser, Rients Engelhard Niks
