A tonoplast‐localized magnesium transporter is crucial for stomatal opening in Arabidopsis under high Mg2+ conditions

What is it about?

Stomatal opening in epidermal cells is very important for gas exchange and transpiration. We show for the first time that magnesium is involved in stomatal opening and that a novel magnesium transporter localized at the tonoplast is required for maintaining magnesium homeostasis.
