Phylogenetic analysis of PtNIP1;1 with selected
MIPs from the four classes: NIPs, plasma membrane intrinsic proteins
(PIPs), tonoplast intrinsic proteins (TIPS), and small and basic
intrinsic proteins (SIPs). The scale indicates nucleotide substitutions
per amino acid position. Organism abbreviations are as follows: At,
Arabidopsis; Gm, G. max; Lj, L. japonicus; Os,
Oryza sativa; Pa, P. abies; Pt, P.
taeda; Zm, Z. mays. Accession numbers are: AtNIP7;1,
