Endosymbiosis and biodiversity

Abstract

Endosimbioza ima važnu ulogu u postanku i evoluciji eukariotske stanice. Različiti plastidi nastali su nizom endosimbiotskih odnosa te uzrokovali raznolikost u svijetu algi. Endosimbioza hidre i Chlorelle predstavlja tipičan primjer dugotrajanog mutualističkog odnosa u kojem oba organizma imaju koristi. S druge strane, Elysia i Ambystoma pripadaju novootkrivenim nespecifičnim simbiozama. Fotosintetske simbioze osiguravaju organizmima svojevrsnu prednost jer mogu preživjeti u uvjetima bez hrane. Moguće je da ovakvi odnosi postoje u puno više organizama nego što je zabilježeno te su potrebna daljnja istraživanja koja će dati odgovore na neka, još otvorena pitanja te pružiti uvid u bioraznolikost koju osiguravaju ovi odnosi.Endosymbiotic relationships play an important role in the origin and evolution series of endosymbiotic events. Endosymbiosis between hydra and Chlorella represents a long-term mutualistic relationship in which both organisms benefit from each other. On the other hand, Elysia and Ambystoma are examples of the unusual symbioses, waiting yet to be fully understood. Associations with photosynthetic organisms provide an advatange to a host because it can survive in conditions without food. It is possible that these relationships exist in more organisms then that were observed so far. Further research is needed to provide the answers and give insight into the biodiversity that is shaped by symbiotic relationships
