The origin of the photosynthetic organelle (plastid) in eukaryotes >1 billion years ago led to the evolution of algae and plants, which form the base of the food chain for life on our planet. The plas
When cyanobacteria originated and diversified, and what their ancient traits were, remain critical unresolved problems. Here, we used a phylogenomic approach to construct a well-resolved 'core' cyanob
Aerobic photoheterotrophs (AAPs) are a functional group of bacteria that can utilize sun light to produce ATP, thus providing additional energy source. They are widely distributed in the oxygen-contai
Cyanobacteria propelled the rise of oxygen and marked an epic transformation of life on earth. The early evolution of Cyanobacteria and oxygenic photosynthesis have been difficult to retrace, partly b
The evolution of increased competitive ability (EICA) hypothesis and the shifting defense hypothesis (SDH) predict that evolutionary changes occur in a suite of traits related to defense and growth in
