The biological clock regulates a wide range of physiological processes in plants. The biologically closed electrochemical circuits in the leaves of C. miniata were analyzed in vivo using the charge stimulation method. C. miniata memorizes daytime and nighttime. The biologically closed electrical circuits with voltage gated ion channels are activated the next day, even in the darkness. At continuous light, C. miniata recognizes nighttime and increases the input resistance to the nighttime value even under light. These results show that the circadian clock can be maintained endogenously and has electrochemical oscillators, which can activate voltage gated ion channels in biologically closed electrochemical circuits. The activation of voltage gated channels depends on the applied voltage, electrical charge and speed of transmission of electrical energy from the electrostimulator to the C. miniata leaves. We present the equivalent electrical circuits in C. miniata and its circadian variation to explain the experimental data.
