Solanum tuberosum Assembly and Gene Annotation
About Solanum tuberosum
Solanum tuberosum (potato) is the worlds fourth most important food crop after rice, wheat and maize. Potatoes were first introduced outside the Andes four centuries ago, and it is estimated that by the year 2020 over two billion people will depend on it for food, feed, or income. It belongs to the Solanaceae, a diverse family of agriculturally important species, including tomato, eggplant, pepper, tobacco, and petunia. The potato genome consists of 12 chromosomes and has a (haploid) length of approximately 840 Mb, making it a medium-sized plant genome. While many potato lines are tetraploid, this sequenced accession corresponds to homozygous diploid line (double haploid) S. tuberosum phureja DM1-3 516 R44.
Genome sequencing was performed by the Potato Genome Sequencing Consortium using a BAC libary, fingerprinted and aligned into physical map contigs. This was complemented by whole genome shotgun approaches with 454 and Illumina sequencing.
Annotation was carried out by the Potato Genome Sequencing Consortium using Cyrille2.
