Interspecific hybridization may trigger species radiation by creating allele combinations and traits. Cultivated potato and its 107 wild relatives from the Petota lineage all share the distinctive trait of underground tubers, but the underlying mechanisms for tuberization and its relationship to extensive species diversification remain unclear. Through analyses of 128 genomes, including 88 haplotype-resolved genomes, Zhang et al. revealed that Petota is of ancient hybrid origin, with all members exhibiting stable mixed genomic ancestry, derived from the Etuberosum and Tomato lineages ca. 8-9 million years ago.

The genomic features of the genome of the autotetraploid potato (Solanum tuberosum): (a) gene density (number of genes per Mb; red) and percentage of TE-related sequence (yellow) within 2-Mb windows along the four haplotypes of each of the 12 chromosomes (Chr. 1-12); (b) landscapes of methylation in CG (purple), CHG (blue), CHH (gray) context within 2-Mb windows; the links in the center show >600 structural rearrangements >100 kb found between the four haplotypes of each chromosome; light blue and red boxes refer to the maternally and paternally inherited chromosomes.
