Title: Organellogenesis: Provide, Divide, and Rule

Abstract: Mitochondria and plastids are the oldest known  endosymbiont-derived organelles. However, describing the actual process of  integration of the endosymbiont with the host (termed  organellogenesis)  is  where we still often end up with a cart before the horse. To understand the  order and importance of events through which endosymbionts transition into  cellular organelles, more evolutionary cell biology data are needed on key  organellogenesis events such as protein translocation system establishment,  horizontal/endosymbiotic gene transfer, cell division control, and a full  takeover of the symbiont’s genetic information processing  (replication, transcription, and translation) by the host cell. Recent  results from highly  integrated insect and protist endosymbionts, i.e., non-model systems that  were so far mostly characterized only with genomics data, are showing all  features typical for organelles, blurring the line between endosymbionts and  organelles. However, these novel systems also show that organellogenesis  might follow a winding path with organism-specific outcomes. In this talk, I  will present some of our recent results on highly integrated symbioses.  The  results improve our understanding of the transition from an endosymbiont to  a cellular organelle which is central to the hypotheses about the origin and  evolution of the eukaryotic cell.
