FlyAtlas 2013 (now aka ‘FlyAtlas 1’) allows users to explore the way that different genes are expressed in the tissues of Drosophila melanogaster. It is based on hybridizing tissue mRNA to microarrays representing the Drosophila genome — work performed in the Dow laboratory in the University of Glasgow. FlyAtlas 2013 presents a different interface from that on the original FlyAtlas site.


Gene: For a particular gene, find details of its expression in different tissues.

Category: For a group of genes with related functions, find details of their expression in different tissues.

Profile: For a particular gene, find others with a similar pattern of expression in different tissues.

Tissue: For a given tissue, find the genes of a particular category with the greatest expression.

Top: For a given tissue, find the genes that are most highly expressed there (e.g. ‘top 20’).

Development: For a given tissue, find genes that change in expression between larva and adult.

The experimental work underlying this web application was described in 2007 in a paper in Nature Genetics by Venkat Chintapalli, Jing Wang and Julian Dow.

The web application itself was built by Scott W. Robinson and David P. Leader, and is described in a paper in the Database issue of Nucleic Acids Research for 2013.


FlyAtlas 2 — our new site presenting RNA-Seq, rather than microarray, data — is now live. Results from queries in FlyAtlas 2013 provide access to the corresponding data in FlyAtlas 2 through the ‘link-out’ icon.
