The evolutionary history of their rubisco protein is used to classify them into alpha and beta types, and the evolution of these organisms resulted in an oxygen rich atmosphere.
Phycobilisomes are a type of light-harvesting structures found in these organisms, and NtcA transcription factors regulate the expression of nitrogen metabolism genes in them. The KaiC phosphorylation cycle maintains circadian rhythms in these organisms. The evolutionary history of their rubisco protein is used to classify them into alpha and beta types, and the evolution of these organisms resulted in an oxygen rich atmosphere. Endosymbiosis of these organisms with eukaryotic cells is thought to have resulted in chloroplasts, though they are often named as a type of algae. For 10 points, name these organisms named for their blue-green appearance.
