how plants regulate low amounts of calcium

Calcium in Plants

INTRODUCTION. Calcium is an essential plant nutrient. As the divalent cation (Ca 2+), it is required for structural roles in the cell wall and membranes, as a counter‐cation for inorganic and organic anions in the vacuole, and as an intracellular messenger in the cytosol (Marschner, 1995).Calcium deficiency is rare in nature, but excessive Ca restricts plant communities on calcareous soils.

Calcium deficiency (plant disorder) - Wikipedia

Calcium (Ca) deficiency is a plant disorder that can be caused by insufficient level of biologically available calcium in the growing medium, but is more frequently a product of low transpiration of the whole plant or more commonly the affected tissue. Plants are susceptible to such localized calcium deficiencies in low or non-transpiring tissues because calcium is not transported in the phloem.
