ABSTRACT
Systemic signaling between roots and shoots is required to maintain mineral nutrient homeostasis for optimal metabolism under varying environmental conditions. Recent work has revealed molecular components of a signaling module that controls systemic phosphate homeostasis, modulates uptake and transport in Arabidopsis. This module comprises PHO2, a protein that controls protein stability, the phloem-mobile microRNA-399 and a ribo-regulator that squelches the activity of miR399 towards PHO2 by a novel mechanism. This advance is a significant step for the design of future rational approaches to improve crop phosphate use efficiency.
