Structural and functional changes in root cells induced by calcium ionophore A23187
The shifts of Ca²⁺, K⁺ and proton homeostasis of wheat (Triticum aestivum L. M. cv Ljuba) root cells induced by the Ca²⁺-ionophore A23187 caused different responses, depending on the time of exposure to the ionophore. Oxygen consumption and heat production by roots were increased when the Ca²⁺-speci...

| description | The shifts of Ca²⁺, K⁺ and proton homeostasis of wheat (Triticum aestivum L. M. cv Ljuba) root cells induced by the Ca²⁺-ionophore A23187 caused different responses, depending on the time of exposure to the ionophore. Oxygen consumption and heat production by roots were increased when the Ca²⁺-specific effect of A23187 was expressed. Ultrastructural re-organization of cell organelles was found to follow the ion shifts. The endoplasmic reticulum, Golgi apparatus and mitochondria rearranged their membranes following treatment. The increased ion permeability of root cell membranes is proposed to cause an excessive energy expenditure for the restoration of ion homeostasis. |
