Endocytobiosis

Endocytobiosis is the intracellular association between two cells. It can be defined as the symbiotic relationship during which one symbiont inhabits within the cytoplasm of another. Homologous and heterologous are the 2 sorts of cytoplasm. If both the cells are derived from an equivalent taxon or same biont (like e.g. synergids within the microgametophyte of seed plants, it's called as homologous and if partner cells comes from the various taxa, then it's termed as heterologous. This special symbiotic association has the facultative ability to an evolutionary change of a dibiont-system into a replacement mono biont-system bearing a replacement cell organelle, the exogenosome. the simplest examples for this illustration are chloroplasts and mitochondria which are widely believed to be evolved from bacteria that when lived as endosymbionts within the cytoplasm of ancestors of eukaryotic cells. endosymbiosis is accomplished by the concomitant transfer of endosymbionts genes to the host nucleus, by a process referred to as Endosymbiotic Gene Transfer (EGT) and is believed to be vital to cement the interdependence of two symbionts which is amid the import of the nuclear encoded plastid proteins back to the first compartment through a protein import apparatus. the method of EGT is comparatively straightforward because it are often recapitulated within the laboratory
