The #symbioses that gave rise to primary #organelles are key events in the origin of #Eukaryotes. @PierreSGarcia @FredBarras & @SGribaldo use markers from 2 conserved machineries for [Fe-S] cluster biogenesis to support an early emergence of #mitochondria & #plastids within #Alphaproteobacteria & #Cyanobacteria #PLOSBiology https://plos.io/3FNP5E5

Our study on the functional conservation of alphaproteobacterial Mic60 is out in Current Biology! This is consistent with the origin of mitochondrial cristae from alphaproteobacterial ICMs. Free access here: https://authors.elsevier.com/a/1gl4Z3QW8S2PcF
