Schematic overview of major events in evolution of Archaeplastida primary plastids from freshwater cyanobacteria, and the later independent primary endosymbiosis in Paulinella (Rhizaria), from a derived group of marine cyanobacteria (after ref. 7). The cyanobacterium Gloeomargarita shares a most recent common ancestor with plastids of the eukaryotic red, green, and Glaucophyte algae, with an inferred freshwater ancestral habitat. Habitat transitions in red algae are from freshwater to marine in certain lineages. Habitat transitions in green algae are common and the early-diverging lineages of the two phyla of green algae have alternate habitats, so the ancestral form in green algae is uncertain (12).
