The origin of plastids.
It is generally accepted that plastids first arose by acquisition of photosynthetic prokaryotic endosymbionts by non-photosynthetic eukaryotic hosts. It is also accepted that photosynthetic eukaryotes were acquired on several occasions as endosymbionts by non-photosynthetic eukaryote hosts to form secondary plastids. In some lineages, secondary plastids were lost and new symbionts were acquired...
متن کاملThe single, ancient origin of chromist plastids.
Algae include a diverse array of photosynthetic eukaryotes excluding land plants. Explaining the origin of algal plastids continues to be a major challenge in evolutionary biology. Current knowledge suggests that plastid primary endosymbiosis, in which a single-celled protist engulfs and "enslaves" a cyanobacterium, likely occurred once and resulted in the primordial alga. This eukaryote then g...
متن کاملEvolution: Red Algal Genome Affirms a Common Origin of All Plastids
Photosynthetic organelles (plastids) come in many forms and were originally thought to have multiple origins. The complete genome of the thermophilic red alga Cyanidioschizon merolae provides further evidence that all plastids derive from a single endosymbiotic event more than 600 million years ago.
متن کاملA common red algal origin of the apicomplexan, dinoflagellate, and heterokont plastids.
The discovery of a nonphotosynthetic plastid in malaria and other apicomplexan parasites has sparked a contentious debate about its evolutionary origin. Molecular data have led to conflicting conclusions supporting either its green algal origin or red algal origin, perhaps in common with the plastid of related dinoflagellates. This distinction is critical to our understanding of apicomplexan ev...
متن کاملNuclear-encoded, plastid-targeted genes suggest a single common origin for apicomplexan and dinoflagellate plastids.
The phylum Apicomplexa encompasses a large number of intracellular protozoan parasites, including the causative agents of malaria (Plasmodium), toxoplasmosis (Toxoplasma), and many other human and animal diseases. Apicomplexa have recently been found to contain a relic, nonphotosynthetic plastid that has attracted considerable interest as a possible target for therapeutics. This plastid is know...
