Cyanobacteria and algae having complex photosynthetic systems can channelize absorbed
solar energy into other forms of energy for production of food and metabolites. In addition …

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 …

Abstract The Clusters of Orthologous Genes (COG) database, also referred to as the
Clusters of Orthologous Groups of proteins, was created in 1997 and went through several …

Microbial genome sequencing projects produce numerous sequences of deduced proteins,
only a small fraction of which have been or will ever be studied experimentally. This leaves …

The origin of oxygenic photosynthesis in Cyanobacteria led to the rise of oxygen on Earth~
2.3 billion years ago, profoundly altering the course of evolution by facilitating the …

Cyanobacteria played an important role in the evolution of Early Earth and the biosphere.
They are responsible for the oxygenation of the atmosphere and oceans since the Great …

For the past 20 years, the Clusters of Orthologous Genes (COG) database had been a
popular tool for microbial genome annotation and comparative genomics. Initially created for …

The origin of oxygenic photosynthesis was the most important metabolic innovation in Earth
history. It allowed life to generate energy and reducing power directly from sunlight and …

Cyanobacteria were responsible for the oxygenation of the ancient atmosphere; however,
the evolution of this phylum is enigmatic, as relatives have not been characterized. Here we …

The species is a fundamental unit of biological organization, but its relevance for Bacteria
and Archaea is still hotly debated. Even more controversial is whether the deeper branches …
