Factors affecting cation-anion uptake balance and iron acquisition in peanut plants grown on calcareous soils

Abstract

Dicotyledonous plants subjected to Fe-deficiency stress can decrease pH in the rhizosphere by proton excretion and reduce ferric iron by an activated reduction system in the plasma membranes of the root or by reductants released from the roots. The efficiency by which these plants take up Fe may strongly depend on their cation-anion balance. This study… (More)
