Competition between uptake of ammonium and potassium in barley and Arabidopsis roots: molecular mechanisms and physiological consequences
Plants can use ammonium (NH(4)(+)) as the sole nitrogen source, but at high NH(4)(+) concentrations in the root medium, particularly in combination with a low availability of K(+), plants suffer from NH(4)(+) toxicity. To understand the role of K(+) transporters and non-selective cation channels in...
