Abstract The mode of action of the photosynthetic inhibitor produced byPandorina morum was examined by exposingVolvox globator and isolated spinach chloroplasts to a partially purified inhibitor preparation. Oxygen evolution ofVolvox, whole chloroplasts, and broken chloroplasts (-Calvin cycle) was reduced indicating that the substances inhibit the light reactions of photosynthesis. Oxygen evolution studies of other Volvocaceae confirmed the observation thatPandorina morum is not significantly influenced by its own inhibitor. Molecular weight approximation by gel filtration established that the inhibitor has a low, molecular weight (probably below 100 mw).
