Abstract:The regulation of O2 production by cyanobacteria is critical to understanding the coevolution of oxygenic photosynthesis (OP) and Earth's redox landscape. This includes their response to electron donors for competitive anoxygenic photosynthesis, like arsenic. In this work, we assessed the effect of arsenic cycling on photosynthetic activity in a modern cyanobacterial mat thriving beneath an arsenate-rich (~9-10 μM) water column in the high-altitude central Andes, using biogeochemical and omics approaches.
