Bicarbonate Activation of the S-Type Anion Currents Is Restored in Guard Cells of the ΔNC Transgenic Line, Whereas ABA Activation of the S-Type Anion Currents Is Impaired.

(A) Whole-cell currents in guard cell protoplasts of the wild type and the ΔNC transgenic line (slac1-4/ΔNC #7) with or without bicarbonate.

(B) Steady state current-voltage relationships of the whole-cell currents recorded in the wild type (squares), slac1-4 mutant (circles), and the ΔNC transgenic line (triangles) with (closed symbols) or without (open symbols) bicarbonate. Error bars indicate ± se; n = 6 to 11 guard cells.

(C) Whole-cell currents in guard cell protoplasts of the wild type and the ΔNC transgenic line (slac1-4/ΔNC #7) with or without ABA.

(D) Steady state current-voltage relationships of the whole-cell currents recorded in the wild type (squares), slac1-4 mutant (circles), and the ΔNC transgenic line (triangles) with (closed symbols) or without (open symbols) ABA. Error bars indicate ± se; n = 5 to 9 guard cells.
