^a Drosophila melanogaster Release 6, reference genome. All these genes were deposited in the Gene table (Supplementary Figure S1) of the FlyAtlas 2 database.

^bGenes or transcripts in the FPKM or RPM output of the computational analysis of sequence reads.

^cA signal was regarded as an FPKM greater than 2 or an RPM (microRNAs) greater than 100 in at least one tissue.

^d Drosophila melanogaster Release 3, reference genome

^eGenes for which there is at least one unique microarray probe-set.
