High-Affinity Manganese Uptake by the Metal Transporter NRAMP1 Is Essential for Arabidopsis Growth in Low Manganese Conditions[C][W]

Abstract

This study shows that, in order to acquire manganese when concentrations in the soil are limited, Arabidopsis relies on a root high-affinity manganese uptake system catalyzed by the metal transporter NRAMP1. The finding that overexpression of NRAMP1 produces large plants with increased manganese content paves the way for the biotechnological engineering of plants with improved biomass production
