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 internal transcribed spacer regions of the bb locus of a number of Drosophila species have been analysed and compared.
The nucleotide sequence of bb from twelve species of the obscura group reveals the presence of a secondary structure in the A+T-rich region that may explain the generation of minor insertions/deletions found in this region that generate length polymorphisms.
A biochemical phylogeny of the subgenus Sophophora has been constructed using RNA sequencing to assess the relationship among species. Results show that the branching of willistoni and saltans groups of the subgenus is very ancient and probably predates that of the subgenus Drosophila. The other groups and subgroups are clustered into three main lineages: the melanogaster and oriental subgroups, the montium subgroup and the ananassae subgroup of melanogaster (with the fima and obscura groups).
