Updated 21 December 2017

Below is a detailed list of tracks available on the D. melanogaster GBrowse viewer.

Reference Genome Annotations (iso-1)

Note: The genome release is shown in the top right corner of the screen, e.g. D. melanogaster (R6.07). The number before the decimal refers to the version of the genome sequence, currently, Release 6 (R6) (Hoskins et al, 2015), which does not change between major releases. The number after the decimal point refers to the version of the annotation set, which may be updated at each release. The D. melanogaster gene set consists of gene models manually annotated by FlyBase annotators (with the exception of some classes of small non-coding RNAs) (Matthews, et al., (2015). G3 (Bethesda) 5(5):777-801).

Gene Span Shows the total extent of the transcribed region of an annotated gene (including non-coding genes), with direction of transcription indicated. No transcript substructure is shown; corresponds to the entire extent defined by all annotated transcripts. Hyperlinked to Gene Report; label shows FlyBase gene symbol.

Transcript SO:0000673 Shows the exon (wider bars) and intron (black line) structure of each annotated coding transcript, with direction of transcription indicated. Hyperlinked Transcript Report; if label option is on, shows FlyBase symbol.

CDS Shows extent of sequence encoding each specific polypeptide, with direction of transcription indicated; introns indicated as narrow lines. Hyperlinked to Polypeptide Report; if label option is on, shows FlyBase symbol.

Natural TE SO:0000101 Shows the extent of a natural transposable element in the sequenced strain (at the time it was sequenced). Hyperlinked to Natural Transposon report; if label option is on, shows FlyBase symbol.

Repeat region Regions of genomic repeats and low complexity DNA sequences, as computed using RepeatMasker and RepeatRunner (Smith, et al., 2007).

General

Estimated Cytological band Approximate extent of the classical cytological chromosome bands described by Bridges. See Computed cytological data in FlyBase for a detailed description of how this computed cytological location is calculated. See FlyBase Maps for a collection of polytene chromosome images.

3-frame translation (forward) If zoomed out (greater than 400bp), shows ticks at sites of stop codons for the three frames on the forward strand. If zoomed in (400bp or less), shows predicted translations for each frame, using single-letter amino acid code.

3-frame translation (reverse) If zoomed out (greater than 400bp), shows ticks at sites of stop codons for the three frames on the reverse strand. If zoomed in (400bp or less), shows predicted translations for each frame, using single-letter amino acid code.

DNA/GC Content If zoomed out (greater than 100bp) shows a graphic of GC content calculated over 10bp intervals. If zoomed in (100bp or less), shows the double-stranded DNA sequence.

Aligned Evidence

cDNA D. melanogaster cDNA sequences from large-scale submissions submitted to the sequence databases; shows the exon (wider bars) and intron (black line) structure, and direction of transcription. Sequences are aligned to release 6 by NCBI and submitted to FlyBase. Some genomic DNA submissions, including third party submissions, are included in this tier.

EST ("expressed sequence tag") Indicated in light green. Partial sequence of a cDNA; shows the exon (wider bars) and intron (narrow bars) structure, and direction of transcription. Sequences are aligned to release 6 by NCBI and submitted to FlyBase.

other aligned sequences D. melanogaster aligned nucleotides submitted to the sequence databases. Sequences are aligned to release 6 by NCBI and submitted to FlyBase. Some genomic DNA submissions, including third party submissions, are included in this tier.

RNA-Seq based exon junctions Indicated in blue. Orientation of the junction is indicated by an arrowhead in the center of the junction. Mousing over the glyph for a RNA-Seq junction activates a pop-up indicating the total read counts for the junction. The read counts are separated based upon which dataset the information is from (modENCODE or Baylor, see below for Dataset Report links). See the BCM_1_RNAseq_junctions and modENCODE_mRNA-Seq_U_junctions Dataset Reports.

PeptideAtlas peptides Indicated in yellow. Alignment of peptide sequences determined by mass spectroscopy, derived from polypeptides isolated from the sequenced strain at various developmental stages. Contributed by the Center for Model Organism Proteomes, SystemsX and Research Priority Project of the University of Zurich, Switzerland. For more information, see Peptide Atlas

Transcription Start Sites (modENCODE), embryo Transcription start site (TSS) regions identified by integrative analysis of ESTs, CAGE or RLM-RACE, modENCODE. The horizontal extent of the blue arrow indicates the range over which 90 percent of the TSS signal is located. The red bars indicate TSS usage at single base resolution along the genome. Clicking on the TSS feature will link to the relevant Sequence Feature report. Note: data for embryonic stages only. See the mE_Transcription_Start_Sites Dataset Report.

Transcription Start Sites (RAMPAGE), peak calls Transcription start site regions (peak calls) identified by RAMPAGE-Seq across 36 stages of development, depicted as green arrow glyphs. The arrow points in the direction of transcription.

Transcription Start Sites (RAMPAGE), early embryo 0-12hr, stranded RNA-Seq Profile of capped transcript 5' ends observed by RAMPAGE-Seq for 12 stages of early embryogenesis.

Transcription Start Sites (RAMPAGE), late embryo 13-24hr, stranded RNA-Seq Profile of capped transcript 5' ends observed by RAMPAGE-Seq for 12 stages of late embryogenesis.

Transcription Start Sites (RAMPAGE), larva/pupa/adult, stranded RNA-Seq Profile of capped transcript 5' ends observed by RAMPAGE-Seq for 12 larval, pupal or adult stages.

See the TSS_RAMPAGE Dataset Report.

Transcription Start Sites (MachiBase), stranded RNA-Seq Profile of capped transcript 5' ends observed by MachiBase CAGE-Seq for embryonic, larval, adult male and female (young or old) and S2 cell line samples. See the TSS_MachiBase Dataset Report.

Please note that the signal shown for the Transcription Start Site data (RAMPAGE and MachiBase) is one base off: i.e., the signal is shown one base to the left of where it should be. In the example to the right, the signal should map to the first base (3R:6864324, A) of the ftz transcript, but is instead shown one base to the left (3R:6864323, C). This is a known bug and we're working to fix this.

Protein domains (PFAM) Pfam protein domains identified in annotated proteins, as obtained from InterPro, are mapped to the genome.

Protein domains (SMART) SMART protein domains identified in annotated proteins are mapped to the genome.

The Bloomington Deficiency Kit:

The Bloomington Deficiency Kit is a set of stocks defined by the Bloomington Drosophila Stock Center (BDSC) to provide maximal coverage of the genome with the minimal number of deficiencies having molecularly mapped breakpoints. The BDSC Deficiency Kit also includes deficiencies with breakpoints that have not been mapped molecularly, primarily to provide coverage of gaps between the molecularly defined deficiencies. Since the ends of cytologically characterized deficiencies cannot be placed on the genome map with certainty, the BDSC has defined segments of these deficiencies that fill gaps in molecularly defined coverage for GBrowse display. The endpoints of gap filling segments are derived primarily from overlapping deficiency endpoints and complementation with annotated genes.

BDSC Deficiency Kit: deleted segment Molecularly defined deficiencies are indicated in red. Click the deficiency to go to the Aberration Report. Links to the relevant Stock Report can be found at the bottom of the Aberration Report.

Example region: 2R:16654718..16655037
More information: TRiP-KO report

Predicted sgRNAs
Sequences predicted to be suitable as sgRNAs for genome engineering. These comprise all possible 23-mers in the D. melanogaster Release6 genome assembly that have 1) a 3-prime PAM sequence (NGG) and 2) a 15 bp sequence that is unique to the genome (including the PAM sequence). The seed score for each sgRNA, which ranges from 12 to 15 bases, indicates the uniqueness of the base pairing end of the sgRNA (excluding the PAM sequence). The frameshift score is the percent of frameshift changes predicted by micro-homology around the target site; the higher the score, the better suited the sgRNA for knockout. Because base pair mismatches can be tolerated outside the seed region, predicted sgRNAs were evaluated for potential off-target sites allowing for 3, 4 or 5 mismatches; potential sgRNA sequences are sorted into five browser tracks based on their predicted specificity at different stringencies.
Example region: 2L:7314441..7314673

On the Sequence Feature report, under "associated information" there is a construct listed. Clicking this construct link brings up the associated Construct Report (e.g. http://flybase.org/reports/FBtp0058072.html) on which you can find a link to the Stock Report (e.g. http://flybase.org/reports/FBst0045107.html). Sorry it's so roundabout!

VDRC Vienna Tiles GAL4 lines VDRC-VT Dataset Report. Glyphs represent putative enhancers used to generate fly stocks carrying GAL4 transgenic constructs. Stocks are available from the Vienna Drosophila Resource Center. Clicking the glyph brings up the associated Sequence Feature report (e.g. VT020839), with links to the related stock reports.

Tiling BACs Tiling BAC indicated by narrow gray bar. BAC genomic clones used by the Berkeley Drosophila Genome Project as part of the minimal tiling path used for determination of the D. melanogaster genomic sequence (Celniker SE. et al. 2002).

Pacman Chori-321_BAC CHORI-321_BAC Dataset Report. The blue glyphs indicate the extent of the BAC, inferred from the mapping of the sequenced BAC insert ends; CHORI-321 BAC inserts are, on average, 83 kbp in size.

Pacman Chori-322_BAC CHORI-322_BAC Dataset Report. The blue glyphs indicate the extent of the BAC, inferred from the mapping of the sequenced BAC insert ends; CHORI-322 BAC inserts are, on average, 21 kbp in size.
