How Cyanobacteria changed the WO2rld

In this presentation, I will focus on the possible hurdles faced by early Cyanobacteria on an anoxic Earth. We will look at their potential transition from a freshwater to a saline environment, and then investigate the proposed toxic effects of Fe(II) on oxygen production in two marine strains. Finally, I will introduce our current research investigating Cyanobacterial iron uptake mechanisms and their ability to deal with oxygen free radicals in the basal marine species, Pseudanabaena PCC 7367. While in no way complete, these studies open the way to better understanding oxygenic photosynthesis in Cyanobacteria in times past and offer insight into future adaptations to climate change today.

This talk is part of the CyanoWorld online seminar series, hosted by Nicolas Schmelling and Ilka Axmann, and was held on Zoom on April 8th, 2021.
