A de novo genome assembly of Solanum bulbocastanum Dun., a Mexican diploid species reproductively isolated from the A-genome species, including cultivated potatoes.

ABSTRACT: Potato and its wild relatives are distributed mainly in the Mexican highlands and central Andes of South America. The South American A-genome species, including cultivated potatoes, are reproductively isolated from Mexican diploid species. Whole-genome sequencing has disclosed genome structure and similarity, mostly in cultivated potatoes and their closely related species. In this study, we generated a chromosome-scale assembly of the genome of a Mexican diploid species, Solanum bulbocastanum Dun., using PacBio long-read sequencing, optical mapping, and Hi-C scaffolding technologies. The final sequence assembly consisted of 737.9 Mb, among which 647.0 Mb were anchored to the 12 chromosomes. Compared with chromosome-scale assemblies of S. lycopersicum (tomato), S. etuberosum (non-tuber-bear
