Alignments to Genome
VvGDB displays high quality spliced alignments for EST, cDNA, PUT, and model species proteins.
More about alignments...
- Transcript sequences displayed at VvGDB were aligned to genomic sequence using GeneSeqer, which performs a consensus spliced alignment on ESTs and cDNA, providing both cognate and non-cognate alignments for improved gene prediction (Brendel et al., 2004).
- Related-species predicted proteins were aligned to genomic sequence using GenomeThreader (Gremme et al., 2005).
- Microarray probes (if any) were matched to the PUT assembly sequence using Vmatch and then coordinately transfered to genomic location.
Search / Download
Search or download any splice-aligned sequences, gene models, or genomic sequence from VvGDB. The entire VvGDB dataset can also be downloaded.

Gene Structure Annotation
Help annotate the
Vitis vinifera genome using our yrGATE gene structure annotation tool (
see Overview), aided by
GAEVAL tables that flag problematic gene models.

Custom Track Display
Distributed Annotation Service (DAS) (
see Overview) is available for displaying remotely served genome alignments at VvGDB, as well as for displaying selected VvGDB tracks on a different genome browser (e.g. Ensembl, GBrowse).
How to use DAS...
To add a DAS track to VvGDB using our DAS client, first select desired genome coordinates above and click "Go", then select menu item "Configure -> Add Track" and paste in the appropriate DAS URL.
To view VvGDB tracks in another genome browser (e.g. Ensembl, Gbrowse) using our DAS server, first find the appropriate xDAS Server URL on our DAS overview page, then follow instructions on the remote browser website for adding the remote track. NOTE: DAS service available for certain tracks only.
For more details, refer to DAS section in our Genome Browser help pages.
Additional custom track display features are under development.
Annotated Protein Alignments
A searchable table of splice-aligned, annotated protein models from one or more related species. Select from the left menu under Gene Annotations -> Splice-Aligned Proteins.
