Auxin transport in suspension-cultured soybean root cells : I. Characterization.

abstract：:The ionic specificity of IAA-induced acidification by Avena coleoptiles was studied, using zwitterionic, presumably impermeant buffers. The acidification was almost totally dependent on divalent cations with an order of effectiveness of Ca(2+) >/= Sr(2+) > Mn(2+), Mg(2+); whereas other polyvalent cations tested were i...
