TaALMT1 permeability to other monovalent and divalent anions. A, Mean I/V relationships of the outward currents recorded from TaALMT1-expressing and control cells (preloaded with malate or water) bathed in a solution containing 9.6 mm Cl⁻ (black circles), 9.6 mm NO₃⁻ (white circles), or 9.6 mm SO₄²⁻ (white diamonds). All solutions contained an additional 4.6 mm Cl⁻ in the background (see “Materials and Methods” for ionic compositions; n = 10). B, Comparison of the outward current conductance recorded in TaALMT1-expressing and control cells (preloaded with malate or water) under the ionic conditions shown in A. The conductance was estimated by linear regression of the three most positive test potentials from the I/V relationships shown in A.
