Predicted proteins encoded by TaHKT2;1 7AL-1 in cultivars Krichauff and Berkut. a The cytoplasmic, trans-membrane, and p-loop domains are identified in pink, purple and green backgrounds respectively. Conserved glycine residues representative of the cation selectivity filter are indicated in red. Amino acid differences at residues 2, 27, 131 and 452 are in blue. b Predicted 3D models of superimposed proteins encoded by TaHKT2;1 from Krichauff and Berkut, side view (right) and top view (left). The yellow regions indicate differences in the p-loop (p.D452Y) and cytoplasmic (p.H131Y) domains between Berkut and Krichauff and the position of cation selectivity filter glycine molecules are indicated in red
