Abstract

Endosimbioza je jedan od najvažnijih evolucijskih koraka u razvoju eukariotske stanice. Ona nam objašnjava kao su se razvili organeli poput mitohonrija i koloroplasta. Nakon postavljanja teorije nije bilo puno saznanja kako je došlo do endosimbioze i kakav odnos imaju domaćin i simbiont. Kako bi se razjasnili mehanizmi endosimbioze bili su potrebni prikladni modelni organizmi. Takvi su rod trepetljikaša Paramecium i njegovi simbionti. Endosimbioza s rodom Holospora daje uvid u to kako se odvijala primarna endosimbioza, a endosimbioza s rodom Chlorella u mehanizme sekudarne endosimbioze. U ovom radu smo pobliže upoznali proces endosimbioze u trepetljikaša koji nam pruža u uvid u moguće mehanizme evolucije eukariota. Za daljna istraživanja endosimbioze su potrebne nove metode kako bi se detaljnije razriješio misterij nastanka eukariota.

Abstract (english)

Endosymbiosis is one of the most important evolutionary step in the development of a eukaryotic cell. This theory explains the origin of organels like mitochondria and chloroplasts. After setting up the theory there wasn't a lot of knowledge on how endosymbiosis occurred and what kind of relationship exsists within the host and symbiont. In order to clarify the mechanisms of endosymbiosis there was a need for suitable model organisms. One of them is ciliate genus Paramecium and its symbionts. Endosymbiosis with Holospora species offer us a view on primary endosymbiosis, and endosymbiosis with Chlorella species could clarify secondary endosymbiosis. In this article we took a closer look on the process of endosymbiosis in ciliates, which provides us with the insight into possible mechanusms of eukaryote evolution . For further research of endosymbiosis, new methods are needed in order to fully resolve the mystery of the emergence of eukaryotes.
