The haplotype-resolved T2T genome assembly of the wild potato species Solanum commersonii provides molecular insights into its freezing tolerance

Abstract

The potato is the most important tuber crop, playing an important role in ensuring world food security. The genome of the cultivated species (DM, a doubled monoploid type) was first released in 2011 and has been continually updated as the most popular reference (Yang et al., 2023). Recently, a high-quality assembly of tetraploid C88 was released (Bao et al., 2022). These studies have made great contributions to potato research. The cultivated potato is sensitive to freezing and multiple diseases, and these traits can be improved by incorporating the exotic diversity of wild species.
