Research Abstract

Remarkably developed vascular systems in nodes of grass plants play a pivotal role for preferential distribution of mineral nutrients to the developing young leaves and grains, although the molecular basis were not understood. In this research, transporters for Zn, Cu and Mn in rice nodes were identified and the important contributions to the distinct distribution pathways for each element were unraveled.
