Variation screening of four wild species and evolutionary analysis of peach genome. a SNPs, small indels, SVs, and CNVs in P. mira, P. davidiana, P. kansuensis, and P. ferganensis compared to P. persica. b Core and dispensable gene families of four wild peaches and P. persica. c Gene Ontology annotation of genes specific in each species. d Estimation of divergence times of 15 species and identification of gene family expansions and contractions. Numbers on the nodes represent the divergence times from present (million years ago, Mya). MCRA, most recent common ancestor. e Distribution of Ks (synonymous mutation rate) values of orthologous genes between six genomes of the Prunus species and strawberry
