内容简介:Oxygenic phototrophs have played a fundamental role in Earth’s history by enabling the rise of atmospheric oxygen paving the way for complex life. Their origin fundamentally transformed the biology and geochemistry of our planet. I will give an overview about key evolutionary events in ...
Thus, the scarcity of reliable heterocystous cyanobacterial fossils significantly hampers our understanding of the evolution of complex multicellularity among cyanobacteria, their role in regulating geochemical cycles in the geological past, and our ability to calibrate cyanobacterial molecular clocks. Here,...
The evolutionary diversification of cyanobacteria: Molecular-phylogenetic and paleontological perspectives Cyanobacteria have played a significant role in Earth history as primary producers and the ultimate source of atmospheric oxygen. To date, however, how and... A.,Tomitani,A.,... - 《Proceedings ...
Cyanobacteria are among the earliest of inhabitants of Planet Earth and their existence can be traced back to 3.8 billion years. Their oxygenic photosynthesis led to the gradual conversion of the Earth‟s atmosphere from an anaerobic to an aerobic one. This change enabled the advent of aerobic ...
They evolved early in Earth history. As bacterial primary producers, cyanobacteria occupy a privileged position among organisms due to their role in the carbon and nitrogen cycles. They are widely adapted to different extreme environments and play an important role, especially in cold polar and ...
This oxygen had played very important role in conversion of anaerobic earth atmosphere into an aerobic one. They have the ability to fix atmospheric N2 either independently or in symbiotic association. Some species are highly nutritive and are being used for food supplements. They are also used ...
Both eDNA and iDNA can be used for gene transfer and manipulation, which may play a key role in horizontal gene transfer for cyanobacterial species (Cohen and Gurevitz, 2006). Since ARGs presenting as either eDNA or iDNA may possess significant differences in their mobility and availability to...

Cyanobacteria constitute the most widely distributed group of photosynthetic prokaryotes found in almost all realms of the earth and play an important role in Earth’s nitrogen and carbon cycle. The gradual transformation from reducing atmosphere to oxidizing atmosphere was a turning point in the evolut...
