The cav genes and duplications in the 8 new sequenced Drosophila genomes were identified by tBLASTn search in Flybase (http://flybase.org/blast/). For these genes, a GI number corresponding to the scaffold DNA sequence is indicated. cav homologs and duplication in other species are identified with their ID number.
For each gene, the orthologous region in the D. melanogaster genome surrounding the identified cav homologous gene is indicated as follows: chromosome and neighbor genes. D. mel cav means that the synteny block is conserved between the gene of interest and cav from Drosophila melanogaster.
