On the origin of oxygenic photosynthesis and Cyanobacteria

Abstract: Summary Oxygenic phototrophs have played a fundamental role in Earth’s history by enabling the rise of atmospheric oxygen (O2) and paving the way for animal evolution. Understanding the origins of oxygenic photosynthesis and Cyanobacteria is key when piecing together the events around Earth’s oxygenation. It is likely that photosynthesis evolved within bacterial lineages that are not extant, so it can be challenging when studying the early history of photosynthesis. Recent genomic and molecular evolution studi… Show more

“…Photosystem II (PSII) is the only enzyme that catalyzes the light-driven oxidation of water, a thermodynamically demanding reaction that drives photosynthesis, sustaining life on our planet (Hohmann-Marriott and Blankenship, 2011;Sanchez-Baracaldo and Cardona, 2020;Vinyard et al, 2013). This multi-subunit membrane protein complex is located in the thylakoid membranes of cyanobacteria, algae and plants.…”

“…The origin of oxygenic photosynthesis is considered a turning point in the history of life, marking the transition from the ancient world of anaerobes into a productive aerobic world that permitted the emergence of complex life [1]. Oxygenic photosynthesis starts with photosystem II (PSII), the water-oxidising and O 2 -evolving enzyme of Cyanobacteria and photosynthetic eukaryotes.…”

“…The closest modern descendants of the ancestral cyanobacteria that evolved into modern marine plankton cyanobacteria are filamentous non-heterocystous Synechococcales (Sánchez-Baracaldo, 2015; Sánchez-Baracaldo and Cardona, 2020). KatG was likely present in ancestors of marine cyanobacteria (Bernroitner et al, 2009; Zamocky et al, 2012), whereas KatE was likely horizontally transferred from Proteobacteria and Planctomycetes to some cyanobacterial linages (e.g.…”
