Figure 4From: Origin and diversification of the basic helix-loop-helix gene family in metazoans: insights from comparative genomicsPhysical linkages detected between Nematostella bHLH genes. The bHLH genes are in red, putative non-bHLH intervening genes are in blue. A = gw.168.63.1, gene similar to the uncharacterized Drosophila CG13990 gene; B = estExt_fgenesh1_pm.C_570004, gene similar to Q9QXA6 (Glycoprotein-associated amino acid transporter b0+AT1) from Mus musculus; C = fgenesh1_pg.scaffold_57000051, gene similar to Drosophila CG18497.
