Peronospora farinosa is a plant pathogen. It causes downy mildew on leaves of wild and cultivated Amaranthaceae: Amaranthus, Atriplex, Bassia, Beta, Chenopodium, Halimione, Salsola, Spinacia, etc. In the past, the forms of Peronospora on these different genera, and their species, were given different species names, but these downy mildews are now generally considered to be forms of one species, P. farinosa (see Index Fungorum). Some of the forms on important crop plants have been given names as formae speciales, notably f.sp. betae on sugar beet (= P. schachtii) and f.sp. spinaciae on spinach. Such host specialization possibly also exists with respect to the various wild amaranthaceous hosts of P. farinosa.
Downy mildew resistant spinach plant
ActiveUS12644129B2Microbiological testing/measurementVector-based foreign material introductionBiotechnologySpinacia
The present invention relates to downy mildew, and especially downy mildew caused by the plant pathogen Peronospora farinosa, resistant spinach plants (Spinacia oleracea). The present spinach plants include a downy mildew resistance providing genomic fragment from Spinacia tetrandra. Specifically, the present invention relates to spinach plants being resistant to downy mildew, wherein the spinach plant includes a downy mildew resistance providing genomic fragment from Spinacia tetrandra such as spinach plants including in their genomes one or more nucleic acid sequences selected from the groups consisting of SEQ ID No. 1, SEQ ID No. 3, SEQ ID No. 5, SEQ ID No. 7, SEQ ID No. 9, SEQ ID No. 11, SEQ ID No. 13, SEQ ID No. 15, SEQ ID No. 17, SEQ ID No. 19, SEQ ID No. 21, SEQ ID No. 23, SEQ ID No. 25, SEQ ID No. 27, SEQ ID No. 29, SEQ ID No. 31, SEQ ID No. 33 and SEQ ID No. 35.

Downy mildew resistance in spinach
PendingCN122458843APeronospora effusaSpinacia
The present invention relates to an allele designated beta-WOLF 28 which confers resistance to at least one race of Peronospora farinosa (P. farinosa) Peronospora effusa ) wherein the protein encoded by said allele is a CC-NBS-LRR protein comprising in its amino acid sequence: a) at its N-terminus the motif "MAEIGYSVC"; and b) the motif "HVGCVVDR"; and wherein said protein has an amino acid sequence having in order of increasing preference at least 95.5% sequence similarity with SEQ ID NO: 11. When present in homozygous form in a spinach plant, said allele confers full resistance to at least P. farinosa races Pe:1, Pe:2, Pe:3, Pe:4, Pe:5, Pe:6, Pe:7, Pe:8, Pe:9, Pe:10, Pe:11, Pe:12 and Pe:13 and does not confer resistance to races Pe:14, Pe:15, Pe:16, Pe:17, Pe:18 and Pe:19.
