- Аннотация: Post-illumination transients of the membrane potential were revealed in cells of Anthoceros punctatus upon short (1–2 s) irradiation with photosynthetically active light. An initial fast depolarization of the cell by 20–30 mV after a lag period of 2 s and a subsequent slow repolarization were recorded with micro-electrodes positioned both in the chloroplast and in transparent parts of the cell. The potential changes of similar kinetics were also observed upon continuous illumination. Post-illumination potential changes were abolished by 3-(3, 4-dichlorophenyl)-l,l-dimethylurea and dicyclohexylcarbodiimide and were stimulated by the addition of NH4Cl. It is assumed that the light-triggered potential change across the plasmalemma of A. punctatus are determined by the light activation of chloroplast ATPase. This assumption is further supported by observations of post-illumination transient increase of the chlorophyll fluorescence in preparations of A. punctatus.
