Abstract：Abstract: Magnesium (Mg), one of the essential nutrients for plant growth and development, plays a funda-mental role in many physiological and biochemical processes. High Mg stress affects plant growth and deve-lopment. However, little is known about the regulatory mechanisms of plant response to high Mg stress so far. Magnesium transporter 6 (MGT6) is the first reported protein in plants that is localized to the plasma mem-brane and mediates the uptake of Mg2+ in plant roots under low-Mg conditions. The present study showed that Arabidopsis thaliana MGT6 mutants and those with silencing of MGT6 by RNA interference were stunted and had yellow cotyledons, but would recover from these symptoms by a certain Ca2+ concentration. The results suggest that MGT6 may respond to high Mg stress by regulating the homeostasis of Ca2+/Mg2+ concentrations.
