“…In the Pyrinae, pairs of S-RNase alleles showing high sequence similarity are commonly found, even among distantly related species (Raspé and Kohn 2002). Bokszczanin et al (2009) recently illustrated this, by reporting an example of highly conserved S-RNase alleles belonging to Malus, Sorbus, and Crataegus species. While the S-RNase gene has been widely studied and is well characterized in species of this taxonomic group, the identity of the pollen S still remains uncertain.…”

The recent analysis of the S-locus region of apple and Japanese pear, two species of Pyrinae (Rosaceae), suggested multiple and different F-box genes (called SFBBs) as candidates for the male determinant (pollen S) of RNase-based gametophytic self-incompatibility in these two species. Here, we followed a phylogenetic approach to take advantage of the pattern of molecular evolution of the S-locus of Pyrinae in characterizing SFBB homologs belonging to S-haplotypes of apple and three species of Pyrus (European, Japanese, and Chinese pears). Our results suggested that the S-locus region of Pyrinae contains no less than six SFBB members and that its structure seems to be rather conserved between apple and pear species. In accordance with the prevailing theory on S-haplotype evolution, the pollen S is expected to have coevolved with the S-RNase and to show some common features derived from the long-term evolution under frequency-dependent balancing selection, i.e., high sequence diversity, evidence of positive selection, and shared ancestral polymorphisms. Using this conceptual framework, we present evidence that some SFBB genes may be better candidates for pollen S in Pyrinae than others. Overall, the SFBB genes analyzed exhibited much lower sequence diversity than their associated S-RNases; likewise, they showed little or no evidence of positive selection. However, evidence of coevolution with the S-RNase clearly emerged for two of them. Altogether our results suggested different evolutionary histories for different SFBBs putatively derived from their distinct involvement in self-incompatibility.

“…This allele is rather similar to P. communis S d , which is identical to P. ussuriensis S 35 . It indicates that this allele might have been inherited from the common ancestor of these taxa, as 97-98% identity of trans-specific and trans-generic Salleles within the Maloideae family was shown (Bokszczanin et al 2009). Non-synonymous SNPs were detected in the RHV region of 'Citromalma' S 1 and 'Tordai alma' S 2 ; their function requires verification.…”

Apple exhibits self-incompatibility controlled by the multiallelic S-locus. Twenty-three old apple cultivars were S-genotyped using three different approaches (allele-specific polymerase chain reaction (PCR) + cleaved amplified polymorphic sequences (CAPS), consensus PCR + sequencing and consensus PCR+CAPS) to compare the robustness and reliability of these techniques and characterise genotypes from the Carpathian basin that might be useful in resistance breeding. Best results were obtained using the ASPF3 and ASPR3S consensus primer pair that detected 96% of all alleles carried by the 23 cultivars tested. Flow cytometry analysis was also needed to control the completeness of the genotypes as was seen in case of a tetraploid cultivar with only three assigned S-alleles. The genetic disparity between the old Carpathian basin and modern apple cultivars was indicated by differences in allele frequency data (S 9 , S 24 and S 26 ) as well as single nucleotide polymorphisms in S 1 , S 2 , S 7 S 24 and S 26 and indels in S 20 and S 26 alleles. An alignment of partial genomic sequences indicated trans-specific and transgeneric evolution of S-ribonuclease alleles in the Maloideae subfamily (S 26 and S 28 ) and a possibly recent introgression event (S 1 ) between Malus×domestica and Malus sylvestris. These data suggest that the genome of old cultivars from the Carpathian basin was enriched by several Malus taxa and are free from the consequences of modern breeding. These cultivars may contribute to the widening of the genetic basis of cultivated apple and prevent genetic erosion in future commercial cultivars.

“…Whereas, over 20 S-haplotypes are reported in other Prunus species such as almond, sweet cherry, plum, apricot, and Japanese apricot (Ushijima et al 2003(Ushijima et al , 2004Yamane et al 2003a, b;Romero et al 2004;Vaughan et al 2006;Zhang et al 2007;Wu et al 2009Wu et al , 2013. In apple, S-haplotype profiling has been widely used in characterizing apple cultivars (Janssens et al 1995;Bokszczanin et al 2009;Kim et al 2009;Long et al 2010;Minamikawa et al 2010). However, there are only a few reports on S-haplotype profiling of wild Malus species.…”

. 2015. Identification and characterization of S-RNase genes and S-genotypes in Prunus and Malus species. Can. J. Plant Sci. 95: 213Á225. Most Rosaceae fruit trees such as Prunus and Malus species exhibit gametophytic self-incompatibility that is genetically controlled by the S-locus. In turn, the S-locus contains at least two tightly-linked S-determinant genes, a pistil S-RNase and a pollen SFB. In this study, S-genotypes of 120 cultivated and wild Prunus accessions (peach) and seven wild Malus accessions (crabapple) have been characterized. Among cultivated Prunus genotypes, four S-RNase alleles, designated S 1 , S 2 , S 3 , and S 4 , have been identified, and they share typical structural features of S-RNases from all other self-incompatible Prunus species. Four S-genotypes, S 1 S 2 , S 1 S 3 , S 1 S 4 , and S 2 S 2 , were identified in peach cultivars, while only one S-genotype S 1 S 2 for wild Prunus species. The S 1 S 2 genotype is predominant in peach cultivars, accounting for 58.3% of all evaluated accessions. Similarly, four SFB alleles were identified in peach cultivars and wild accessions. However, all the four SFB alleles encode truncated proteins due to a frame-shift mutation, resulting in loss of hyper-variable and/or variable regions. For Malus species, a total of 14 S-RNase alleles are identified, and of those, two alleles encode truncated proteins. Overall, the genetic variation of both S-RNase and SFB genes in peach is significantly lower than that of S-RNase and SFB genes in self-incompatible Malus and/or Prunus species. The relationship between the genetic variation of SFB genes and the diversification of S-RNase genes in Rosaceae is also discussed.Key words: Prunus, Malus, Self-incompatibility, S-genotypes, S-RNase, Pollen, S-determinant Gu, C., Wang, L., Korban, S.
