Multiple sequence alignment of predicted proteins encoded by TaHKT2;2 genes from homeologous chromosome 7AL, 7BL and 7DL containing four membrane-pore-membrane structures (I to IV). Cytoplasmic, trans-membrane, and p-loop domains are in pink, purple and green backgrounds respectively. Conserved glycine residues representative of the cation selectivity filter are indicated in red. Differences in amino acid residues are shown in blue
