Phylogeny of EFhd genes. A phylogenetic tree with equal distances between different taxons was generated using efhd1 as search parameter (http://www.treefam.org/cgi-bin). Search parameters were: accession number TF320736 / clean / equal distance / show taxa / none / exp / selected species. Only representative species are shown for convenience. On the right hand side the employed transcript sequences are shown. Chick, chicken (Gallus gallus), Brare, zebrafish (Danio rerio), Xentr, frog (Xenopus tropicalis), Cioin, Hydra (Ciona intestinalis), Drome, fruitfly (Drosophila melanogaster), Caeel, worm (Caenorhabtidis elegans).
