December 2004 update:

A publication reporting this work, "Comparative genome sequencing of Drosophila pseudoobscura: Chromosomal, gene and cis-element evolution", has been published in Genome Research (January 2005). The annotated sequence is now available in Flybase (to query and to browse) and in GenBank. Supplemental information, including the filtered BlastZ alignments and the set of protein alignments used for dN/dS analysis, is also available.

We would like to thank everyone involved in this great project.

Previous Updates

The Drosophila Genome Project at the HGSC is sequencing the second Drosophila species: Drosophila pseudoobscura. The euchromatic portion of the genome (125 Mb) is being sequenced to approximately 7-fold coverage using a whole genome shotgun approach and is being assembled using the HGSC's assembly engine, Atlas. Comparison of this species assembly with the recently completed sequence of Drosophila melanogaster is expected to offer important further insights into the biology of this historic model for experimental genetics.

Project Goals:

• Library and Strain Info
• Generation of high quality paired-end sequencing reads from the following library sources:
• 2kb plasmid - 1.8 million reads completed
• 6kb plasmid - 770,000 reads
• 40kb fosmid - 45,000 reads
• 175kb BAC - 12,000 reads
• Generation of assembled draft and finished high-quality sequence for 16 fosmid projects
• Generation of 50,000 ESTs and 1,000 full-length cDNA sequences from Drosophila pseudoobscura cDNA libraries
• Generation of a whole genome assembly using the Atlas genome assembler
• Annotation of the Drosophila pseudoobscura genome, primarily by comparison to the finished Drosophila melanogaster genome

• Preliminary assembly (unordered contigs)
• BLAST
• FTP
• Fosmid projects -- Sequencing Project Browser
• Sequence Traces -- NCBI Trace Archive
• Annotated sequence -- Flybase
