Summary: How do endosymbionts become
organelles? Understanding early
events in plastid evolution

Summary
What factors drove the transformation of the cyano-
bacterial progenitor of plastids (e.g. chloroplasts) from
endosymbionttobonafideorganelle? Thisquestion liesat
the heart of organelle genesis because, whereas intra-
cellular endosymbionts are widespread in both unicellular
and multicellular eukaryotes (e.g. rhizobial bacteria,
Chlorella cells in ciliates, Buchnera in aphids), only two
canonical eukaryotic organelles of endosymbiotic origin
are recognized, the plastids of algae and plants and the
mitochondrion. Emerging data on (1) the discovery of non-
canonicalplastidproteintargeting,(2)therecentoriginofa
cyanobacterial-derived organelle in the filose amoeba
