WitrynaCyanobacteria(also called blue-green algae) are an ancient group of photosynthetic microbes that occur in most inland waters and that can have major effects on the water quality and functioning of aquatic ecosystems. They include about 2000 species in 150 genera, with a wide range of shapes and sizes. WitrynaThe core proteins of PSII involved in oxygenic photosynthesis originated during the early Archean, well before the GOE occurring around 2.3 billion years ago. Most extant …
WitrynaMolecular clock analyses have previously shown that marine planktonic cyanobacteria evolved toward the end of the Pre-Cambrian ( Sánchez-Baracaldo et al., 2014; Sánchez-Baracaldo, 2015; Schirrmeister et al., 2015a) likely contributing to the widespread oxygenation of the oceans.
