Now online! Ancient hybridization underlies tuberization and radiation of the potato lineage
Ancient hybridization underlies tuberization and radiation of the potato lineage
Genomic and functional analyses reveal that the potato lineage originated from a homoploid interspecific hybridization event between the Tomato and Etuberosum lineages 8–9 million years ago. The alternate inheritance of highly divergent parental alleles drove the origin of tubers and explosive species diversification and niche expansion into the high Andes.
