Solanum tuberosum (SolTub_3.0)

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. The potato genome consists of 12 chromosomes and has a (haploid) length of approximately 840 Mb, making it a medium-sized plant genome. The Solanaceae are a diverse family of agriculturally important plant species, including tomato, eggplant, pepper, tobacco, and petunia.

Assembly

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

Annotation was carried out by the Potato Genome Sequencing Consortium using Cyrille2.

Additional analysis was carried out in house: non coding RNA genes have been annotated using tRNAScan-SE, Rfam, and RNAmmer.

Regulation

  • Mapping using GSNAP of transcriptomics sequences from 16 samples from different tissues submitted to the ENA SRA as part of study ERP000527.
  • ~194,000 EST sequences have been aligned to the genome with Exonerate.
