Characterization of S haplotypes in flowering Prunus species. a Microsynteny at the S-locus regions between wild P. yedoensis and fruit crop Prunus (P. persica and P. mume). There are two S haplotypes in the heterozygous Pyn genome (31 kb of S1 and 35 kb of S2) compared to a single S haplotype in the homozygous Pp and Pm genomes. Syntenic genes are connected with lines. b Relative expression levels of the S-RNase and SFB genes in different tissues are presented by the average fragments per kilobase million (FPKM) value from three independent biological replicates. c S haplotype network in a natural Prunus population. A total of 15 S haplotypes from 12 accessions, which are distributed sympatrically in a natural habitat on Jeju Island, were identified. Accessions are placed according to their relative geographic location in the natural habitat. Shared S haplotypes between accessions are connected with lines of the same color. Chloroplast genome lineage, showing < 10 nucleotide differences in the protein-coding sequences of the whole chloroplast DNA (Additional file 12: Table S11), is also presented in the green box
