Potato Genome Sequencing Consortium Public Data Release
Sequence files and other related information for the Potato Genome Sequencing Consortium (PGSC). The PGSC has sequenced two potato species: the heterozygous diploid S. tuberosum Group Tuberosum cultivar, RH89-039-16 (RH), and the doubled monoploid S. tuberosum Group Phureja clone DM1-3 (DM)
- December 5,2013 - The PGSC DM v4.03 pseudomolecule GFF3 files have been updated to correct an error. An error occurred when converting positions of annotations on the PGSC DM v3 superscaffolds to the PGSC DM v4.03 pseudomolecules if a superscaffold was split. This error affected 1628 genes, which are listed in this file. The error only affected the location of annotations and not the sequence. The FASTA and AGP files for the PGSC DM v4.03 pseudomolecules were not affected.
- November 1, 2013 - A paper describing the construction of the PGSC v4.03 pseudomolecules for S. tuberosum Group Phureja DM1-3 has been published in the journal G3: Genes, Genomes, Genetics.
- September 4, 2013 - The PGSC v4.03 pseudomolecule FASTA sequence, AGP, and GFF3 annotation is now available
- July 9, 2012 - The PGSC v2.1.10 pseudomolecules (based on version 3 of the DM genome assembly) were updated to v2.1.11 pseudomolecules. This new version is the same as the S. tuberosum Group Phureja DM1-3 Version 2.1.10 AGP Pseudomolecule Sequences (available below) except the gaps greater than 50 kbp have been changed to 50 kbp
- Dec 15, 2011 - The transcript and representative transcript files have updated due to the original files containingsome corrupted sequences.

Information about the RNA-Seq Gene Expression Data
The format of the files:
1st column: gene ID
2nd column: library 1
3rd column: library 2
last column: functional annotation of the gene
The reads were mapped to S. tuberosum Group Phureja DM1-3 superscaffolds using Tophat (v1.4.1) [which made use of Bowtie (v1.0.0)] The FPKM values were calculated by Cufflinks (v1.3.0) using v3.4 representative model set only.
Tophat was run with "-i 10 -I 15000" parameters, which set a minimum intron size of 10bp (-i 10), and a maximum intron size of 15,000bp (-I 15000). These values are the minimum and maximum intron feature lengths present in the v3.4 GFF. Paired-end libraries were aligned in single end mode.
Cufflinks was run with the same maximum intron size of 15,000bp (-I 15000)
Functional annotation was based on best BLASTX hits using the CDS sequences against UniRef100. The text was assigned using a first informative best-hit strategy, which considers best BLASTX hits where E <= 1e-5, but excludes hits with non-informative functional text (eg: "Whole genome shotgun sequence of line..."). The text is also programmatically cleaned to remove some misleading and low-information strings. For gene-level annotation, the transcript-level functional text was concatenated, so there will be some redundancy due to variations in the annotation string assigned to the different isoforms.
Putative Orthologous Groups (OrthoMCL)
- 12_plants_all_orthomcl_parsed.txt.zip -
The predicted proteomes (representative peptides only) of 12 plant species were used for identification of putative orthologous groups using OrthoMCL with deafult parameters (Li et al., 2003). The plant species included are: Arabidopsis thaliana, Brachypodium distachyon, Carica papaya, Chlamydomonas reinhardtii, Glycine max, Oryza sativa, Physcomitrella patens, Populus trichocarpa, Solanum tuberosum, Sorghum bicolor, Vitis vinifera and Zea mays.
This tab-delimited file has the following columns:

Potato Diversity Arrays Technology (DArT) markers:
The potato DArT array contains 7,680 probes obtained using genomic representations from a potato diversity panel also including selected probes from tomato (234) and Capsicum (54). The DArT probes were sequenced using financial support from The James Hutton Institute, UK under their Potato Genome Sequencing Grant* and are made available by Diversity Arrays Technology Pty Ltd, Yarralumla ACT 2600, Australia. This work is part of the Potato Mapping Group, a subgroup of the Potato Genome Sequencing Consortium (PGSC).
