Kyle, A. Palloix] As knowledge of the genetic resources available for disease resistance in crop plants increases, the development of conventions for naming disease resistance loci that can be applied consistently across plant species and pathogens becomes increasingly important. Resistance gene designations have not followed regular conventions, exemplified by the locus and allele designations for resistance to three potyviruses: potato virus Y (PVY), tobacco etch virus (TEV) and pepper mottle virus (PepMoV) in Capsicum spp. To further complicate the situation, no system of nomenclature has been proposed that directly reflects the genetic associations (linkage, pleiotropy) commonly observed between resistance to distinct viral pathogens. In some cases, the locus designations completely obscure the possible relationship or identity among the resistance genes. We propose a nomenclature that clarifies the genetic and biological relationships among potyvirus resistance genes in pepper, and should represent a generally useful scheme for other crops and pathogen groups. Further, it avoids the need for revision of gene symbols due to taxonomic changes of host or pathogen. As a general rule, we propose the symbol pvr for potyvirus resistance locus, followed by a number specific to each locus, according to the chronological order in which they were identified. Alleles at each locus will be differentiated using numerical superscripts. At present, there is clear evidence for four independent loci in Capsicum, each with alleles that confer resistance to viral isolates that belong to one or more of the viruses, PVY, PepMoV and TEV. When resistance to more than one potyvirus is attributed to a factor or factors that are identical or very thightly linked, the factor(s) that control that resistance will be given one symbol until it is clearly demonstrated that there are distinct alleles and/or loci involved at which time a new allele and/or locus designation will be made with the next highest available number.
