Title: Endosymbiotic Theory: Models and Challenges ☆
Abstract: The endosymbiotic theory posits that some eukaryotic cell organelles, such as mitochondria and plastids, evolved from free-living prokaryotes. Available data indicate that the mitochondrial endosymbiosis initiated the evolution of the eukaryotic cell, as suggested by Margulis. Plastid evolution has a complex history with eukaryote–eukaryote endosymbioses, known as secondary endosymbioses, occurring after the initial cyanobacterial endosymbiosis. Some of these plastids still preserve reduced algal nuclei called nucleomorphs. Mitochondria and plastids are stable eukaryotic cell constituents, but losses of these organelles have also been documented. New organelles of prokaryotic origin have been identified in the amoeba Paulinella chromatophora and aphid insects.
