Phylogenetic tree of AQPs from Pisum sativum sequences and other plants generated in MEG5.1 software. Subfamilies are labeled by brackets at the right side. Sequences of P. sativum are indicated by filled triangles. Information of the known 32 AQP sequences and GenBank accession numbers used are as follows: Arabidopsis thaliana, AtPIP1;1 (AEE80201), AtPIP1;2 (AEC10622), AtPIP1;3 (AEE27312), AtPIP1;4 (AEE81879), AtPIP1;5 (AEE84748), AtPIP2;1 (AEE79084), AtPIP2;2 (AEC09362), AtPIP2;3 (AEC09363), AtPIP2;4 (AED97364), AtPIP2;7 (AEE86464), AtPIP2;8 (AEC06543); Mimosa pudica, MpPIP1;1 (BAD90696), MpPIP2;1 (BAD90697), MpPIP2;2 (BAD90698), MpPIP2;3 (BAD90699), MpPIP2;4 (BAD90700), MpPIP2;5 (BAD90701); Cicer arietinum, CaPIP7a(XM_004490904), CaPIP2;1(XM_004496224), CaPIP2;7(XM_004505936); Glycine max, GmPIP2;7(XM_003538126), GmPIP2 (XM_003540128), GmPIP;7a (XM_003544062), GmPIP2;5 (XM_003556184); Medicago truncatula, MtPIP11(XM_003600815), MtPIP1;1(AF386739), MtPIP2;1(AY059380), MtPIP2;7(XM_003606335); Phaseolus vulgaris, PvPIP1;3 (DQ855475), PvPIP2;2 (EF624001), PvPIP2;3 (EF624002); Medicago sativa subsp.
