The potato genome was sequenced using a homozygous doubled-monoploid potato clone. Analysis of the genome sequence revealed:
1) The potato genome is approximately 844 megabases in size, with over 39,000 predicted protein-coding genes.
2) There is evidence of at least two whole genome duplication events in the evolutionary history of potato, consistent with paleopolyploidy.
3) Compared to other plant genomes sequenced so far, the potato genome contains over 2,600 genes that are specific to the asterid plant clade, to which potato belongs.
