Název v původním jazyce

Evolutionary and Molecular Aspects of Plastid Endosymbioses

Popis výsledku v původním jazyce

Plastids are membrane-bound organelles that bestow phototrophic abilities to eukaryotes. They are products of endosymbiotic evolutionary events that involved eukaryotic hosts and phototrophic intracellular symbionts, represented by cyanobacteria in so-called primary plastid endosymbioses or phototrophic eukaryotes in so-called complex endosymbioses [1,2]. Plastids harbor a multitude of housekeeping and metabolic functions, directly or indirectly related to photosynthesis, which are deeply integrated with the host cell and physiology. Plastids are remarkably widespread, we know of at least 13 independent primary or complex endosymbiosis events across the tree of eukaryotes (reviewed in [3]). However, the maintenance of the photosynthetic machinery is costly, therefore, the secondary losses of photosynthesis outnumbers that of endosymbioses. Due to this deep integration with the host, plastids themselves are seldom completely lost. Their reductive evolution is gradual, with non-essential functions being lost along with photosynthesis, and other plastid features, such as thylakoids, genomic DNA, and metabolic pathways, becoming lost when they turn out to be unnecessary for the host. The complete elimination of plastids is extremely rare and has only been reported for parasitic apicomplexans (Cryptosporidium and gregarines) and dinoflagellates (Hematodinium) to date.
