Abstract: | The European pear (Pyrus communis) carries the S-RNase-mediated gametophytic self-incompatibility (GSI) system. The S-haplotype is conferred by an S-locus, which contains the style-specific expressed S-RNase, and the pollen-specific expressed F-box genes (SFB). Both the S-RNase and the SFB genes are multi-allelic and each is characteristic of one of the S-haplotypes. Therefore, they are ideal markers for molecular S-genotyping. In this work, for the first time, seven haplotype-specific SFBs were isolated from European pears. Particular primers for each of these SFBs were generated, thus providing an additional tool for S-genotyping of European pear cultivars. |
