The diel light cycle modulates microcystin content in continuous cultures and natural communities of Microcystis: Implications for bloom monitoring

This study shows microcystin levels in Microcystis cultures and natural blooms vary predictably with the diel light cycle, suggesting time-of-day should be standardized in monitoring efforts.

The ornithine-arginine cycle supported a toxic, metalimnic Planktothrix rubescens bloom

The study investigates the metabolic pathways of a toxic Planktothrix rubescens bloom using metagenomics and metabolomics, revealing the role of the ornithine-arginine cycle in its ecological success.

Mitomycin C eliminates cyanobacterial transcription without detectable lysogen induction in a Microcystis-dominated bloom in Lake Erie

The paper tests lysogeny in Microcystis blooms using mitomycin C and finds it ineffective for inducing prophage, suggesting standard protocols are unsuitable for freshwater cyanobacterial studies.
