According to their sequence homology and sub-cellular location, plant AQPs could be subdivided in four subgroups: plasma membrane intrinsic proteins (PIPs): PIP1, PIP2 and PIP; tonoplast intrinsic proteins (TIPs), which further subdivided into 5 subgroups: a, b, g, d and e-TIP; nodulin 26-like intrinsic proteins (NIPs); small and basic intrinsic proteins (SIPs, further subdivided into 2 subgroups: SIP1 and SIP2); GlpF-like intrinsic proteins (GIPs).
