Regulation of calcium and magnesium homeostasis in plants…
Introduction. Calcium (Ca) and magnesium (Mg) are abundant metal elements in the earth crust and the ionic forms (Ca 2+ and Mg 2+) in the soil serve as essential plant nutrients.Plants utilize Ca 2+ to strengthen cell walls, neutralize vacuolar anions, and provide stress protection. In contrast to a high content of total calcium in …

The most severely affected plants exhibit the greatest reduction in Mg-chelatase activity. Heme levels and protoporphyrinogen oxidase activity were the same for mutant and wild-type plants. We suggest that a block in Mg-chelatase activity in these mutants could account for the other traits of their pleiotropic phenotype previously described in ...

Effects of Magnesium Deficiency on Plants
If the deficiency is not corrected, chlorosis will eventually develop in the new growth. A continuous magnesium deficiency leads to leaf necrosis and the fall of the old leaves. Magnesium is also the activator of various enzymes, and a lack will lead to a decrease in enzyme activity, which will also affect plant growth.
