A dichotomous key for the discrimination of the already known S-RNase alleles in potato species
The potato species exhibit gametophytic self-incompatibility system controlled by a single S-locus withmultiple S-haplotypes. Each S-haplotype carries two genetically linked genes, S-RNase and SLF, controllingthe female and male specificities, respectively. In the style, the S-RNase gene codes for a...

| description | The potato species exhibit gametophytic self-incompatibility system controlled by a single S-locus withmultiple S-haplotypes. Each S-haplotype carries two genetically linked genes, S-RNase and SLF, controllingthe female and male specificities, respectively. In the style, the S-RNase gene codes for an allele-specificribonuclease that is involved in the rejection of pollen that carries the same S-haplotype. This gene hasfive conserved regions (C1–C5) and two hypervariable domains located between C2 and C3 that play arole in S-RNase allele specificity. Presently, eight nucleotide sequences of S-RNase alleles from Solanumtuberosum and S. chacoense have been reported in potato species. In an effort to discriminate these S-RNase alleles and eventually detect new allelic variants, these sequences were analyzed by in silico PCR,using primers designed on the basis of four conserved regions, and were further examined by restrictionenzyme patterns. The development of the in silico approach led to the creation of a novel dichotomous keywhich was able to unequivocally identify the eight potato S-RNase alleles already known and eventuallydetect putative alleles when the size and/or the restriction pattern of the amplicons were different fromthose predicted. Experimental data validates the utility and efficiency of the dichotomous key |
