Phylogenetic relationships of the 37 CrAQPs from C. rosea, the 75 GmAQPs from soybean, and the 35 AtAQPs from Arabidopsis. The phylogenetic tree is constructed using MEGA 6.0 software, with ClustalW alignment, neighbor-joining (NJ) method, the bootstrap method, and 1000 repetitions. All five subfamilies of AQP gene family are well separated in different clades and represented by different color background
