Description In our study, we examined effects of semipurified Microcystis extract containing microcystins (0.2-20 nM corresponding to 0.2-20 mu g L(-1)) on age-induced cell differentiation of filamentous cyanobacterium Trichormus variabilis. Microcystins or other bioactive peptides could affect conservation, overwintering, and nitrogen-fixation in filamentous cyanobacteria under environmental conditions but also contribute to the understanding of possible signaling function of cyanobacterial metabolites.
