Phosphate-Metal Interactions Govern Root Development
Chemistry assigned phosphate (Pi) and phosphorylated intermediates dominant roles in metabolism, but it also rendered the macronutrient a genuinely limiting factor of plant productivity. Pi bioavailability is often obstructed by low Pi mobility in soil and antagonized by metallic toxicities, which force roots to actively seek and selectively acquire the vital element. The sensory mechanisms that monitor external Pi status and transmit the edaphic signal to locally inform root development are at the center of current research. This review highlights the Pi acquisition strategy of the Arabidopsis root system and discusses the emerging framework of local Pi sensing in the context of complex interactions between Pi and its major associated metallic cations, Fe3+ and Al3+.
