3. Potato ( Solanum tuberosum L.) Family: Solanaceae Genus: Solanum Section: Petota Petota  section consists of more than 100 tuber-bearing species, and is sister to the non-tuber-bearing  Etuberosum  section and the  Lycopersicon  section that comprises tomato species. Commercial production of potato is dominated by autotetraploid cultivars that are propagated using seed tubers. Reinventing potato from a clonally propagated tetraploid to a true seed-propagated diploid has the potential to considerably accelerate genetic improvement, and would enable the genome design of a crop that has been highly recalcitrant to the use of molecular breeding and genomics approaches.

4. Genome evolution and diversity of wild and cultivated potatoes 4 Diploid potatoes represent around 70% of the wild and landrace potato species, and the vast diversity among them has not been fully characterized or made use of in previous breeding programs. Furthermore, the effects of the evolution of a clonal reproduction strategy on potato genomes and the evolutionary mechanisms of tuberization are largely unexplored. So far, several potato genome sequences have been released, which have been important resources for genetics and breeding. However, the minor portion of biodiversity in the  Petota  section that is captured by these genomes is insufficient to obtain a comprehensive understanding of the potato genome and tuber evolution. Here we report genome sequences and analyses of 44 diploid potatoes, as well as 2 species in the  Etuberosum  section. Our findings provide insights into the alteration of potato genomes during the evolution of tuberization, and will enable genome design for new diploid hybrids.

5. Pan-genome of the Petota Section S elected 44 representative accessions based on the phylogenetic relationships of 432 accessions. 20 landraces , covering 5 indigenous cultivated diploid groups (landrace), 4 accessions from  Solanum candolleanum  (CND) , which is considered the progenitor of cultivated potatoes, and another 20 wild potato species.

6. Genome evolution and diversity of wild and cultivated potatoes 6 generated an average of 24.5 Gb (approximately 30-fold relative to the estimated haploid potato genome size of around 800 Mb) high-fidelity (HiFi) reads for the 44 accessions (Supplementary Table  1 ); these were de-novo-assembled into raw assembled contigs with heterozygous regions retained and into monoploid assembled contigs (MTGs), with average N50 contig sizes of 9.10 Mb and 23.33 Mb, respectively
