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 Diffusers 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 events that inhibit root growth.Here, we identified HYPERS
