Citation: Interpretive Summary: Potato is the world’s number one vegetable crop. The potato is in the same plant family as the tomato pepper and. Tomato is both an important crop as well as a model for scientific discovery. Information from the International Tomato Genome Sequencing Project will help provide information for understanding its close relative the potato. Efforts are also underway on the potato by the Potato Genome Sequencing Consortium. In combination these two genome sequencing efforts will provide the background to study the cultivated potato. Direct sequencing of cultivated potato varieties is difficult because of the large genome size, its complexity and the abundance of non-essential DNA. We are examining the genome of the wild potato relative Solanum bulbocastanum using an Ilumina Genome Analyzer Classic platform to take an initial genome wide look at a potato.
Technical Abstract: Potato is the world’s number one vegetable crop. The potato is a member of the Solanaceae family that contains other crops such tomato pepper and eggplant as well as model species tobacco and petunia. Tomato is both an important crop as well as a model species for genetic and physical genomic information. The extensive genetic map is currently being combined with the International Tomato Genome Sequencing Project that will complete the diploid tomato as a reference Solanaceae genome. Efforts are also underway to elucidate the entire genome of a diploid potato by the Potato Genome Sequencing Consortium. In combination these two genome efforts will provide an excellent backbone to serve as reference for studies with heterozygous tetraploid potato cultivars. Direct sequencing of tetraploid potato varieties is complicated due to a combination of the large genome size, the high degree of heterozygosity and the abundance of long highly homologous repetitive DNA. Whole genome shotgun sequencing of the diploid wild potato relative Solanum bulbocastanum using the Ilumina Genome Analyzer Classic platform has been used to take the first steps toward a genome wide look at a potato.
