Welcome to the AAA Wiki - created to coordinate the Assembly, Alignment and Annotation of the now 12 sequenced Drosophila genomes. Creating and editing pages on this Wiki requires registration.
The first main publications from these genomes sequences are now available

Sequencing
The 12 Drosophila genomes to be analyzed here include the published sequences of D. melanogaster and D. pseudoobscura, as well as 10 additional genomes sequenced in response to two community white papers. D. simulans and D. yakuba were sequenced by the Washington University Genome Center. D. erecta, D. ananassae, D. virilis, D. mojavensis and D. grimshawi were sequenced by Agencourt, Inc., D. willistoni was sequenced by the J. Craig Venter Institute, and D. persimilis and D. sechellia were sequenced to low coverage by the Broad Institute. Additional information about these species and their sequences can be found on the Species Pages.
Assembly
The first complete set of assemblies of all 12 species was released in February 2006 as Comparative Analysis Freeze 1. Details on the assemblies can be found on the Assembly page.
Although the assemblies have been frozen for the first round of papers, we would like to know if you find problems with the assemblies, which can be corrected in the next releases. Please post assembly problems here.
Annotation
Several groups are already producing annotations based on the frozen assemblies, and additional groups are encouraged to participate in the annotation process. We will be producing a reconciled set of gene predictions in late spring, and will release all annotations as they are produced. For updated information on annotation plans see the Annotation and Annotation Coordination pages.
- Formats and Naming Schemes
- Comparison of predicted gene sets
- Annotation Submission
- Consensus sets
- Annotation exceptions
Alignment
Several groups are already producing alignments of all or some of the 12 genomes. Raw alignments and tools for their access will be posted on the Alignment page.
Chromosomal Maps
The chromosomal working group will discuss the new cytogenetic maps being developed for 11 species. In addition, this group will map the scaffolds to the cytogenetic maps.
Analysis
Analysis groups are self-assembling in the following areas, other research directions are encouraged.
- Coding gene evolution
- Multigene families
- Gene structure
- Genome rearrangement
- X vs. autosome
- Noncoding RNA
- Transposable elements
- Noncoding DNA
- mtDNA
- Phylogenetics
- Y chromosome
- Heterochromatin
- Species and Clade specific features
- Evolution of sex and reproduction related genes
- Gene Validation
Phylogeny
- Including entries to all species.
Tools
We will maintain a complete list of tools useful for the analysis of these genomes on the Tools page. Please post tools there.
Papers
The group is working on several papers describing these analyses. More info is available here.
