Subcellular location of TaHAK1b-2BL and its roles in potassium uptake and salt tolerance. (A). Subcellular location of TaHAK1b-2BL. Scale bars = 20 µm. (B). Functional complementary assay of TaHAK1b-2BL in a high-affinity potassium uptake deficient yeast mutant. Yeasts transformed with the empty vector (pYPGE15) were used as a negative control. The tested potassium concentrations were indicated above each panel. Serial dilutions (10⁻¹) of yeast culture were plated. (C). Salt tolerance assay of TaHAK1b-2BL. The tested sodium concentrations were indicated above each panel. Serial dilutions (10⁻¹) of yeast culture were plated.
