英文摘要 | State transition and non-photochemical fluorescence quenching in cyanobacteria are short-term adaptations of photosynthetic apparatus to changes in light quality and intensity, however, the kinetic details and relationship are still not clear. In this work, time-dependent 77 K fluorescence spectra were monitored for cyanobacterium Synechocysris PCC 6803 cells under blue, orange and blue-green light in a series of intensities. The characteristic fluorescence signals indicated state transition taking place exclusively under 430-450 or 580-600 nm light or 480-550 nm light at the intensities <= 150 mu E m(-2) s(-1) to achieve a conserved level with variable rate constant. Under 480-500 nm or 530-550 nm light at the intensities >= 160 mu E m(-2) s(-1), state transition took place at first but stopped as soon as the fluorescence quenching appeared. The dependence of appearance, induction period, level and rate constant for the quenching on light intensity suggests that a critical concentration of photo-activated OCPs is necessary and may be achieved by a dynamic equilibrium between the activation and deactivation under light.
