Abstract Copper (Cu) and iron (Fe) are essential micronutrients that toxic when accumulating in excess cells. Thus, their uptake by roots is tightly regulated. While plants sense respond to local Cu availability, the systemic regulation of has not been documented contrast control Fe uptake. abundance phloem suggested act systemically, regulating expression genes roots. Consistently, shoot-to-root signaling disrupted Arabidopsis thaliana mutants lacking companion cell-localized transporter, OLIGOPEPTIDE TRANSPORTER 3 (AtOPT3). We report AtOPT3 also transports heterologous systems contributes its delivery from sources sinks planta. The opt3 mutant contained less phloem, was sensitive deficiency mounted a transcriptional response young leaves. Feeding Cu- or Fe-deficient wild-type seedlings with via leaves downregulated both Fe-deficiency marker These data suggest existence signaling, highlight complexity Cu/Fe interactions, role fine-tuning root responses plant needs.
