Variants of resistance genes or candidates at the protein level. For RYMV1 (a), the allele names cited in Albar et al. [14] and Thiemele et al. [12] are used, but an additional protein variant observed in susceptible accessions was given the name “Rymv1–1-Og2”, and for greater clarity the allele named “Rymv1–1-Og” in [12] was referred to as “Rymv1–1-Og1”. For the RYMV2 (b) and RYMV3 (c) candidate genes, the different alleles were named according to their association (R) or not (S) with RYMV resistance. The CG14 allele was the reference allele. Polymorphisms associated with resistance are indicated in red, whereas those which are not are in green. Important conserved domains are indicated as colored frames. The number of accessions carrying each allele is indicated on the right of the figure, with a distinction between accessions from the set of 165 fully sequenced accessions (without brackets), and accessions from the nine additional resistant accessions (in brackets). The total number of accessions sometimes differed between genes due to missing data, resulting in undefined alleles
