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.

Critical Issues in the Study of Magnesium Transport

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.

Female specific pathogen-free KK and ICR mice were given a stock diet containing Ca 1.2, P 0.8 and Mg 0.27% for 3 weeks; then for 1, 2, 4 or 6 days they were given a diet low in Mg and high in P without or with 0.1% or different amounts of NaF. Some mice were given a diet high in Mg or low in P. The rate of disappearance of plasma urea-14C and glomerular filtration rate were estimated.
