This study reports that cyanobacterial toxins microcystins affect cellular differntiation of filamentous cyanobacterium Trichormus variabilis. Decreased frequency of heterocyte and akinete formation was observed in cultures of T. variabilis exposed for 10 days to environmentally relevant concentrations of microcystins (2-20 ug/L). These results indicate that microcystins may alter processes of conservation, overwintering or nitrogen fixation in filamentous cyanobacteria and thus play an important role in chemical-mediated interspecific interactions and/or signaling.
