title: Is antimycin A a specific inhibitor of the slow rise of the electrochromic absorbance change in intact chloroplasts?
abstract: The inhibitory effect of antimycin A on the slow rise of the flash-induced electrochromic absorbance change was reinvestigated in intact chloroplasts isolated from pea leaves. It is shown that in the absence of nigericin and +K at low repetition rates (less than 0.5 s-1) of the excitation flashes not only the slow (approximately 10 ms) rise but also the initial (much less than 1 ms) rise generated by photosystem 1 is inhibited by antimycin A.
