  • Huge collection of polytene chromosome maps
    Thom Kaufmann has curated a large collection of beautiful polytene map images, now available in the Maps section of the FlyBase Resources page.* This collection includes original illustrations of D. melanogaster polytene chromosomes by Bridges (published in 1935-1942) and Slizynski (published in 1944), as well as electron micrographs by Lefevre (published in 1976). Dr. Kaufmann has also assembled annotated images that combine the original illustrations and/or electron micrographs of polytene or mitotic chromosomes with known sequence, cytology and recombination map data for select genes.** These images have been compiled for the Muller Elements of all 12 originally sequenced Drosophila species, using species-specific polytene images where available, but otherwise showing the D. melanogaster polytene chromosome image as a reference. These annotated maps are also available on the FlyBase Chromosome Maps browser. Images also available for D. melanogaster Y and mitochondrial chromosomes.

    *Polytene images were first made available in October 2016.
    **A full map correspondence table of recombination, cytology and sequence map values for D. melanogaster genes on the reference genome assembly is available in the Maps section of the FlyBase Resources page.

  • Improved recombination map data
    FlyBase has incorporated two datasets that provide genome-wide recombination map values to D. melanogaster genes on the reference genome assembly.* The first dataset is a FlyBase analysis that computes the recombination map position of genes from the known cytological location of over 1200 neighboring P-element insertions and estimates of polytene band size (kb) from Sorsa and colleagues. The second dataset is based on the work of Comeron et al., 2012, who mapped over 100 million SNPs in 5,860 female meiosis events to calculate cross-over frequencies for 100 kbp intervals along chromosomes X, 2 and 3. Cumulative cross-over frequencies along the genome assembly were used to calculate the recombination map position of genes based on their sequence location, as described here. The correspondence of these two datasets is quite good, though estimates for genes in the middle of chromosomal arms can differ by several centiMorgans (cM). For quick access, the FlyBase-calculated recombination map value is shown in a new "Recombination Map" field near the top of the gene report next to other location data.** All data are reported in full in the "Genomic Location and Detailed Mapping Data" section of the gene report. A full map correspondence table of recombination, cytology and sequence map values for D. melanogaster genes on the reference genome assembly is available in the Maps section of the FlyBase Resources page.

    *Recombination map data were first made available in FB2016_05 (September 2016).
    **The new "Recombination map" section was first released in FB2017_01 (February 2017).

    SMART protein domains
    We have added protein domain data from SMART. This domain data supplements the protein domain data already available via Pfam. These data can be seen as new tracks in both JBrowse and GBrowse, on the main FlyBase site and the new "FlyBase 2.0" beta site. On FlyBase 2, these domains also appear as graphics in several types of reports (gene, polypeptide, etc).
  • April 18 (with the release)
    Gene Groups update
    New Gene Groups in this release include: N-terminal acetyltransferases, phosphatidylinositol glycan anchor biosynthesis genes and water channel proteins.
  • April 18 (with the release)
    New sources of Gene Ontology (GO) annotations
    FlyBase has incorporated GO annotations for D. melanogaster genes from four new external sources: GO Central, ParkinsonsUK-UCL, BHF-UCL (Cardiovascular Gene Annotation) and CACAO (Community Assessment of Community Annotation with Ontologies). GO Central is now the largest external provider of GO annotations to FlyBase, adding over 11,000 new annotations to our set. GO Central assigns GO terms based on phylogenetic ancestory using their Phylogenetic Annotation INference Tool (PAINT) to semi-automate the transfer of annotations between species. We have also updated the set of GO annotations provided by UniProt Gene Ontology Annotation curators.
  • April 18 (with the release)
    FlyBase has updated its OrthoDB orthology data from OrthoDB7 to OrthoDB9.1. OrthoDB provides orthology relationships for a broad scope of species and is particularly useful for assessing orthology within arthropods. These data are displayed in the Orthologs → Orthologs (via OrthoDB9.1) section of gene reports.

    DGRC clone resource links
    Links to the DGRC clone resource page have been added to relevant gene reports under Stocks and Reagents → cDNA Clones → DGRC cDNA clones.
  • April 18 (with the release)
    D. grimshawi annotation update (R1.05)
    In the previous FlyBase update (FB2017_01), the new NCBI Gnomon annotations for D. grimshawi (R1.04) were released. However, previously existing transcripts and polypeptides that persisted from R1.3 (pre-Gnomon) to R1.04 (Gnomon) were incorrectly given new names and "FBtr" identifiers. This issue is corrected in this release with an updated D. grimshawi annotation set (R1.05), such that transcripts that existed before the Gnomon update retain their original name and "FBtr" identifier. A mapping file for genes affected by this change is available here.

    Small RNA-Seq data
    Jaaved Mohammed and Eric Lai have generously provided FlyBase with small RNA-Seq coverage profiles for 13 developmental stage, 5 tissues and 26 cell lines. These coverage profiles have been generated by remapping and consolidating hundreds of RNA-Seq experiments characterizing small RNA species (<30nt). These profiles should be of interest to those studying the biology of miRNA, piRNA and siRNA. Many thanks to the Lai lab for these data, which are available as GBrowse tracks under the "small RNA-Seq" section of the tracks listing. Track names for these data are:
    Developmental stages, stranded small RNA-Seq (Lai lab)
    Tissues, stranded small RNA-Seq (Lai lab)
    Tissue culture cells (Schneider + embryonic), stranded small RNA-Seq (Lai lab)
    Tissue culture cells (imaginal disc), stranded small RNA-Seq (Lai lab)

    New orthology data and query tool
    FlyBase has incorporated orthology predictions between genes of 8 model organisms from the DRSC Integrative Ortholog Prediction Tool (DIOPT). These DIOPT-derived orthology calls are now shown explicitly within the 'Orthologs' section of D. melanogaster Gene Reports, alongside our exisiting orthology set from OrthoDB that is biased towards species closely related to D. melanogaster. Both datasets are searchable through the new 'Orthologs' tab of our QuickSearch tool.
  • March 30 (with the release)
    miRNA annotation set update
    The FlyBase miRNA annotation set has been updated to correspond with miRBase release 21. This has added a number of new miRNA annotations for D. melanogaster (18), D. virilis (60) and D. pseudoobscura (1). In addition the remapping of the D. simulans miRBase annotations to the new release 2 assembly resulted in the elimination of 16 miRNA gene annotations, primarily removing redundant annotations that were due to assembly artifacts.
  • March 30 (with the release)
    Systematic nomenclature for D. melanogaster tRNA genes
    We have worked with the Genomic tRNA database (GtRNAdb) to systematically identify and assign informative nomenclature to the ~300 nuclear genes encoding cytoplasmic tRNAs in D. melanogaster. These data are best viewed via the new Gene Group page for these genes here.

    Human Disease Model reports
    The FB2015_04 release of FlyBase includes the addition of Human Disease Model reports, which integrate all the disease-related information from multiple reports in FlyBase. These reports highlight the role of systems modeled in flies on research into human disease and the potential impact of the results on translational research. One of the purposes of this report format is to provide a less specialized entry point for non-Drosophila researchers and for Drosophila researchers newly interested in Drosophila disease model systems.

    Improved esyN interactions graphic on gene reports
    FlyBase has incorporated a number of improvements to the interactive esyN network graphics. In the gene report, users can now choose to display interactions between neighbors (i.e., interactions between interactors of the gene of interest). To make better sense of complicated networks, three different layout options are available: force directed (default), circle and concentric. These configuration options are shown to the left of the esyN display. FlyBase also now offers esyN displays in the interaction report, where the two subjects of the interaction report are highlighted in pink, and common interactors of the two factors are highlighted in purple. The force directed, circle and concentric layout options are also available in these interaction report graphics. Please note that these new configuration options do not work in older versions of Safari (v5). FlyBase would like to thank the esyN group ( for making these new configuration options possible.

    New reports for non-transposable element based insertions
    FlyBase already produces an Insertion Report for insertions of transposable-element based transgenic constructs, e.g. P{GawB}Dllem212. Starting in the fb_2015_03 release, we now also generate an Insertion Report if exogenous DNA is inserted into the genome via non-transposable element-based means. In this case, since no transposable-element ends are present, the ends of the inserted element are designated using 'TI' (for 'transgene insertion') e.g. TI{GAL4}. Please see this Commentary for more information.
  • June 26 (with the release)
    RNA-Seq by Region query tool
    The new RNA-Seq By Region tool reports the average (per base) expression level for a given genomic region in the modENCODE developmental and tissue RNA-Seq transcriptome profiles. This tool allows one to evaluate the approximate expression level of individual exons, parts of exons, introns and/or intergenic regions. It can be accessed from any FlyBase gene report, in the “High-Throughput Expression Data” sub-section of the “Expression Data” section. Please see this Commentary for more information.
    Please note that the tool previously called “RNA-Seq Search” has been renamed to “RNA-Seq Profile Search”; FlyBase hopes this change will prevent possible confusion between the two tools.

    Gene-level genetic interaction data
    A gene-level summary of genetic interaction data for D. melanogaster genes is now being computed each release from the allele-level genetic interaction statements captured by FlyBase (this new summary replaces out-of-date gene-level genetic interaction data that was no longer being maintained). The summary gives an overview of the genetic interactions for a gene, complementing the allele-level statements which give a detailed view of each individual interaction.
    The gene-level genetic interaction data can be accessed in two ways:
    1. The ‘Summary of Genetic Interactions’ section on the Gene Reports contains a table showing the gene-level genetic interaction summary. The table shows which gene(s) have been shown to interact genetically with the gene, together with the nature of the interaction (‘enhanceable’ or ‘suppressible’) and the reference(s) from which the data came in each case.
    2. A bulk file is accessible through the Precomputed Files page (Files menu ⇒ Current release, "Genetic interaction table" under the Genes section). The format is described here.

    New reference mitochondrial genome assembly
    In FB2015_01, a new D. melanogaster mitochondrial genome assembly derived exclusively from the "iso-1" sequenced strain (NCBI KJ947872.2, RefSeq NC_024511.2) replaces the old mitochondrial genome assembly, which was a composite of sequences from various D. melanogaster strains. See the current release notes for more details on the new mitochondrial genome assembly. FlyBase features have been migrated from the old to the new mitochondrial genome assembly. There have been small changes to the nucleotide sequence of the following genes: mt:ATPase6, mt:Cyt-b, mt:ND1-PA, mt:ND4, mt:ND5, mt:lrRNA and mt:ori. The previous mitochondrial assembly continues to be accessible through the archived FlyBase releases.

    D. melanogaster release 6.01
    FlyBase has migrated all D. melanogaster genomic data to release 6 of the BDGP assembly.
    If you have data for which you will need to convert genomic coordinates, the FlyBase Coordinate Converter tool has been updated to convert from R5 → R6 and R6 → R5 coordinates. If you have a large number of coordinates to convert, you may want to consider installing our stand-alone conversion code, posted at FlyBase @ GitHub.
  • July 21 (with the release)
    GBrowse 1 retired
    The migration of FlyBase from GBrowse 1 to GBrowse 2 is complete, and GBrowse 1 will no longer be available through the main FlyBase site.
    With the retirement of GBrowse 1 we will lose Orthoview, which displayed orthology calls between D. melanogaster and other species. GBrowse 1 also supported views of genomic data for a selection of non-Drosophila species; these will no longer be available (the non-melanogaster Drosophila species will continue to be available in GBrowse 2). GBrowse 1 will still be available from inside the archived FlyBase servers.
    In return for these, we gain a number of new features. For a summary, please see this Commentary.
  • July 21 (with the release)
    Chromosome maps removed
    The large aberration map and chromosome map images previously available on FlyBase have had to be retired. The chromosome maps in particular have seen their usefulness degraded by changes in the Google Maps API used to drive most of their features. Both of these map sets were based on Dmel Release 5 coordinate data, which is now obsolete.
    As with all other FlyBase tools that are being retired with the change to Dmel release 6, these maps can still be accessed from within our archived FlyBase servers.
