| Research Abstract |
Genome-wide genetic structural analysis was conducted to 96 species of Amygdalus subgenus by using the SNPs information from ca. 9000 loci in the genome. It was suggested that current domesticated peach(Prunus persica) cultivars formed multiple clusters which had been under the historical artificial selections, to which wild cultivars have not been subjected. Comparison of differences in the genetic diversities among the clusters showed some specific selective sweeps on certain genomic regions of each cluster. Importantly, the clusters of the ornamental flower peaches and the main fruit peaches gave clues for artificial selective pressure on their certain genomic regions, respectively. These genomic regions contained genes apparently related to the characteristics specific to each cluster. It would be suggested that these genes importantly play substantial rolls to maintain the characteristics of each peach cluster and to lead them under the domestication.
