Abstract Chinese cherry (Prunus pseudocerasus) has many natural tetraploid species within Prunus. The pollen grains of tetraploid Chinese cherry are hetero-diploid, the two S-haplotypes in the pollen are a combination of two of the four possible S-haplotypes. The abnormal segregation ratios of pollen-S indicate that a few hetero-diploid pollen grains could inactivate self-stylar S-RNase inside the...
This study identified eight S-haplotype-specific F-box genes (SFB alleles) and one S-haplotype-specific F-box-like gene (SFB-like gene) from genomic DNA by PCR combined with cleaved amplified polymorphic sequence markers in Prunus pseudocerasus and Prunus speciosa. The unknown sequences of C-termini were obtained by thermal asymmetric interlaced PCR. The whole nucleotide sequences of these genes were...
