Updated sequence information for this Drosophila species is no longer provided by FlyBase. Gene model annotations for this species are now updated and maintained at NCBI, using the gnomon automated annotation pipeline. See the NCBI page ‘Eukaryotic genomes annotated at NCBI’.
The FlyBase BLAST tool will continue to support queries against the reference genome of this species, but not queries against annotated transcripts or proteins. For the current release, there is no JBrowse or GBrowse view of the gene model annotations for this species.
The FlyBase archived release FB2017_05 includes the last NCBI annotation update for this species that was imported into FlyBase. That sequence data can be accessed from archived gene reports, via the archived GBrowse tool, and via archived bulk-data downloads.

Please Note This section lists cDNAs and ESTs that fall within the genomic extent of the gene model, which may include cDNAs and ESTs of genes within introns, or of overlapping genes. Please see JBrowse for alignment of the cDNAs and ESTs to the gene model.
For each fully sequenced cDNA the DGRC maintains various forms of the cDNA (e.g tagged or untagged) in several different host vectors for subsequent cloning and expression in Drosophila and Drosophila cell lines.
The phylogenetic relationships and divergence times of 39 drosophilid species have been studied by using the coding region of the Adh gene.
The organization of the Adh gene region in D.hydei is similar to that found in D.mulleri and D.mojavensis. There are three tandem Adh genes: 5' gene is the pseudogene, Dmoj\Adh2 and then the 3' gene Dmoj\Adh1. Deletion of a nucleotide in the second coodon of each pseudogene suggests that the first duplication occurred before the divergence of the hydei and mulleri subgroups. Dhyd\Adh1 and Dhyd\Adh2 are more alike than Dmoj\Adh1 and Dmoj\Adh2. Comparisons of the extent of sequence divergence propose that independent duplication events generated Dmoj\Adh1 and Dmoj\Adh2 in the two lineages.
Structure and nucleotide sequence comparisons of Adh genes proposed that an intial duplication of an ancestral Adh gene generated two Adh genes arranged in tandem. The more 5' gene became a pseudogene while the more 3' gene remained functional through all the developmental stages. A second duplication of this 3' gene resulted in 3 genes: a pseudogene, Dmoj\Adh2 and Dmoj\Adh1.
