FERRIC REDUCTION BY A CYBDOM PROTEIN COUNTERACTS INCREASED IRON AVAILABILITY IN ROOT MERISTEMS INDUCED BY PHOSPHORUS DEFICIENCY

Ferric reduction by a CYBDOM protein counteracts increased iron availability in root meristems induced by phosphorus deficiency

Abstract To mobilize sparingly available phosphorus (P) in the rhizosphere, many plant species secrete malate to release P sorbed onto (hydr)oxides of aluminum and iron (Fe).In the presence of Fe, malate can provoke Fe over-accumulation in the root apoplast, triggering a series of HAIR MASK BLACK CAVIAR events that inhibit root growth.Here, we iden
