Abstract

Тhe effects of carbonic anhydrase inhibitors, such as ions Cu2+ and Zn2+, on the membrane system of chloroplasts in pea leaves were investigated. After treatment of pea leaves with 250 mM Cu2+ or 400 mM Zn2+ we observed changes in the granal structure and compactness of the thylakoids in granae. It was shown that the thickness of granal thylakoids and the interspace between thylakoids increased comparing to control. Changes of the size and structure of thylakoids and granae in treated leaves may be associated with the enhanced accumulation of CO2 in the membrane. It is suggested that the carbonic anhydrase may also play a structural role in chloroplast granae.
