Monophyly of Primary Photosynthetic Eukaryotes: Green Plants, Red Algae, and Glaucophytes
Between 1 and 1.5 billion years ago, eukaryotic organisms acquired the ability to convert light into chemical energy through endosymbiosis with a Cyanobacterium (e.g.,). This event gave rise to "primary" plastids, which are present in green plants, red algae, and glaucophytes ("Plantae" sensu Cavalier-Smith). The widely accepted view that primary plastids arose only once implies two predictions...
متن کاملGene sampling can bias multi-gene phylogenetic inferences: the relationship between red algae and green plants as a case study.
The monophyly of Plantae including glaucophytes, red algae, and green plants (green algae plus land plants) has been recovered in recent phylogenetic analyses of large multi-gene data sets (e.g., those including >30,000 amino acid [aa] positions). On the other hand, Plantae monophyly has not been stably reconstructed in inferences from multi-gene data sets with fewer than 10,000 aa positions. A...
متن کاملAn Early-Branching Freshwater Cyanobacterium at the Origin of Plastids
Photosynthesis evolved in eukaryotes by the endosymbiosis of a cyanobacterium, the future plastid, within a heterotrophic host. This primary endosymbiosis occurred in the ancestor of Archaeplastida, a eukaryotic supergroup that includes glaucophytes, red algae, green algae, and land plants [1-4]. However, although the endosymbiotic origin of plastids from a single cyanobacterial ancestor is fir...
متن کاملSure facts and open questions about the origin and evolution of photosynthetic plastids.
Some eukaryotic groups carry out photosynthesis thanks to plastids, which are endosymbiotic organelles derived from cyanobacteria. Increasing evidence suggests that the plastids from green plants, red algae, and glaucophytes arose directly from a single common primary symbiotic event between a cyanobacterium and a phagotrophic eukaryotic host. They are therefore known as primary plastids. All o...
متن کاملEarly photosynthetic eukaryotes inhabited low-salinity habitats.
The early evolutionary history of the chloroplast lineage remains an open question. It is widely accepted that the endosymbiosis that established the chloroplast lineage in eukaryotes can be traced back to a single event, in which a cyanobacterium was incorporated into a protistan host. It is still unclear, however, which Cyanobacteria are most closely related to the chloroplast, when the plast...
