New preprint from our lab! We explore how the cyanobacterial toxin microcystin enhances CO₂ fixation in Microcystis and show that microcystin coordinates a dynamic CCM with photosynthetic acclimation — without directly affecting RubisCO activity. www.biorxiv.org/content/10.6...
Microcystin-Driven Control of the Carbon-Concentrating Mechanism Shapes CO2 Fixation Dynamics in Microcystis aeruginosa PCC 7806
Bloom-forming cyanobacteria thrive in highly dynamic light environments, yet the mechanisms enabling rapid acclimation to fluctuating irradiance remain poorly understood. Here, we compared light accli...
