Phylogenetic relationships among zebrafish aquaporins. The unrooted phylogenetic tree was constructed using the NJ method. The Escherichia coli homologs (EcAqpZ and EcGlpF) cluster as aquaporins and aquaglyceroporins, respectively. The bar indicates the mean distance of 0.2 changes per amino acid residue.
