The effect of 3-amino-1, 2, 4-triazole (amitrol), an uncoupler of the Q of photosystem II, on growth, heterocyst frequency, H2 production, acetylene reduction (nitrogenase activity) and photosynthetic O2 evolution was studied in Nostoc linckia. Whereas amitrol inhibited growth, acetylene reduction and O2 evolution, it increased heterocyst frequency and H2 production. Exposure of Nostoc linckia to higher concentrations of amitrol caused pronounced fragmentation of filaments into 5- to 10-celled trichomes. The observed effects on growth and other physiological processes may be due to the reduction in reluctant and ATP pool(s).
