Regulation of calcium and magnesium homeostasis in
2017-10-1 Although a family of CorA-type Mg 2+ transporters plays a key role in controlling Mg 2+ homeostasis in plants, more components are yet to be identified. Ca 2+ and Mg 2+ appear to have antagonistic interactions in plant cells, and therefore plants depend on a homeostatic balance between Ca 2+ and Mg 2+ for optimal growth and development. Maintenance of such a balance in response to changing nutrient status in the soil emerges as a critical feature of plant

2011-4-1 However, excess zinc causes serious growth defects such as chlorosis and root growth inhibition (Marschner, 1995). It has been proposed that such growth defects might be a secondary effect of excess zinc caused by deficiency of other essential ions, such as iron or magnesium, which have ionic radii similar to zinc

Magnesium uptake characteristics in Arabidopsis
2018-6-7 Magnesium (Mg2+) absorption and the mechanism regulating its activity have not been clarified yet. To address these issues, it is necessary to reveal the characteristics of Mg2+ uptake in roots. Therefore, we first investigated the Mg2+ uptake characteristics in roots of 1-week-old Arabidopsis plants using 28Mg.

2015-9-23 After potassium, magnesium (Mg) is the second most abundant cation in cells. Numerous physiological processes, such as enzymatic activities and aggregation of ribosome subunits, are Mg-dependent [1,2]. In plants, Mg is the central atom of the chlorophyll molecule. It is generally known that leaves become yellowish when Mg nutrition is limited.
