Abstract excerpt

Leaf Na+ exclusion, mediated by plasma membrane-localised Class 1 High-affinity potassium (K+) Transporters (HKTs), is a key mechanism contributing to salinity tolerance of several major crop plants. We determined previously that the leucine to proline residue substitution at position 189 (L189P) in barley HvHKT1;5 disrupts its characteristic plasma membrane localisation and Na+ conductance. Here, we focus on a...
