Schematic diagram of pan-genome of apple (IMAGE)
Caption
A new comparison and analysis of the genomes of species in the genus Malus, which includes the domesticated apple and its wild relatives, revealed the evolutionary relationships among the species and how their genomes have evolved over the past nearly 60 million years. (a) Family tree of Malus species showing potential evolution of polyploidy — having more than two copies of each chromosome — in the genus. (b) Schematic diagram of pan-genome graph showing relationship between a segment of the M. floribunda genome and the reference Fuji genome.
