The October 2005 Drosophila persimilis genome assembly, which was produced by the Broad Institute at MIT and Harvard, can be downloaded here. To review a list of the assembly's largest 1000 supercontigs ranked by size, click here.

### Sample position queries

A genome position can be specified by a supercontig coordinate range, the accession number of an mRNA or RefSeq entry, a gene name, or keywords from the GenBank description of an mRNA. The following list shows examples of valid position queries for the D. persimilis genome. Note that some position queries (e.g. "huntingtin") may return matches to the mRNA records of other species. In these cases, the mRNAs are mapped to their homologs in D. persimilis. See the User's Guide for more information.
