Role of Zinc Homeostasis in Plant Growth | SpringerLink
Zinc is one of the most important micronutrients required for optimal plant growth and productivity. Paradoxically, a higher concentration of the same can be toxic for the plants, and hence, a constant supply of zinc to maintain an optimal intracellular concentration in plants is required which is referred to as zinc homeostasis.

Zinc And Plant Growth: What Is The Function Of Zinc In Plants
Zinc and Plant Growth. The function of zinc is to help the plant produce chlorophyll. Leaves discolor when the soil is deficient in zinc and plant growth is stunted. Zinc deficiency causes a type of leaf discoloration called chlorosis, which causes the tissue between the veins to turn yellow while the veins remain green.
