Abstract
Sexual self-incompatibility in European pear (Pyrus communis L.) is controlled by a single locus (S-locus) encoding a polymorphic stylar ribonuclease (S-RNase) that is responsible for the female function in pollen–pistil recognition. In this study, genomic DNA sequences corresponding to five new S-RNase alleles (named S 20 , S 21 , S 22 , S 23 , and S 24 ) and to S m were characterized in European pear cultivars. Re-sequencing S q from ‘General Le Clerc’ showed this S-RNase to encode the same protein as S 12 . Based on these findings, a polymerase chain reaction (PCR)-based method was developed for the molecular typing of cultivars bearing 20 S-RNases (S 1 –S 14 , S m , and S 20 –S 24 ) using consensus and allele-specific primers. Genomic PCR with consensus primers amplified product sizes characteristic of the S-RNases S 1 , S 2 , S 4 , S 10 , S 13 , and S 20 . However, the allele groups S 3 /S 12 , S 6 /S 8 /S 11 /S 22 and S 5 /S 7 /S 9 /S 14 /S m /S 21 /S 23 /S 24 amplified PCR products of similar size. To discriminate between alleles within these groups, primers to specifically amplify each S-RNase were developed. Application of this approach in 19 cultivars with published S-alleles allowed re-evaluation of one of the alleles of ‘Passe Crassane,’ ‘Conference,’ and ‘Condo.’ Finally, this method was used to assign S-genotypes to 37 cultivars. Test crosses confirmed molecular results.
