The present invention relates to an allele designated alpha-CMV which confers resistance to CMV when present in a spinach plant, 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: 22) at its N-terminus; and b) the motif “KWMCLR” (SEQ ID NO: 23); and c) an LRR domain that has in order of increased preference at least 95%, 96%, 97%, 98%, 99%, 100% sequence similarity to SEQ ID NO: 10. The allele has a genomic nucleotide sequence which in order of increased preference has at least 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, 100% sequence similarity to SEQ ID NO: 1.

Non R-gene mediated resistance

The present invention relates to a method for modifying the resistance profile of a spinach plant tof sp., comprising introducing a WOLF allele or a resistance-conferring part thereof into the genome of said spinach plant, or modifying an endogenous WOLF allele in the genome of said spinach plant. A WOLF allele encodes a CC-NBS-LRR protein that comprises in its amino acid sequence: the motif 'MAEIGYSVC' at its N-terminus, and the motif 'KWMCLR' for alpha-type WOLF proteins or &#x201c;HVGCVVDR&#x201d; for beta-type WOLF proteins.
