Whole genome resequencing 23 Pyrus accession

Whole genome re-sequencing of the 23 wild and cultivated accessions from Pyrus species collected was performed using an Illumina HiSeq sequencing platform. And the SNPs obtained were used for population structure analysis of Pyrus hopeiensis and other pears. Through a selective elimination analysis, the selection area of wild Pyrus hopeiensis under natural conditions were accurately screened. At the same time, Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) function enrichment analysis of the screened genes were also performed. Our study provided information on genetic variation, evolutionary relationships and gene enrichment in Pyrus hopeiensis population.
