The evolutionary relationships of aquaporins. A phylogenetic tree was generated from human (Hs), Arabidopsis (Ath) and E. coli (AqpZ and GlpF) aquaporin sequences using ClustalX. Members of the aquaglyceroporin (GLP) subfamily are indicated; all other proteins shown belong to the classical aquaporin subfamily.
