Abstract The photosynthetic capability was acquired by the eukaryotic kingdom through endosymbiotic associations with a photoautotrophic prokaryote in a process called primary endosymbiosis, where a cyanobacterium was captured and retained by a primitive mitochondriate protist. Glaucophytes are most likely the first lineage of photosynthetic eukaryotes of primary endosymbiotic origin, which diverged after plastid establishment. It is therefore of particular interest to gain knowledge about the plastid protein repertoire of this algal lineage in order to achieve a comprehensive understanding of the endosymbiotic origin of plastids. The availability of the complete genome data from the Glaucophyte Cyanophora paradoxa not only corroborated the hypothesis of Archaeplastida monophyly, but also provided invaluable data about the evolutionary routes taken by the different Phyla within the Archaeplastida. We present an overview of the knowledge gained since the completion of the draft genome of C. paradoxa with a focus on the transport processes across the plastidial membranes.
