Cyanophora paradoxa

Cyanophora paradoxa is a freshwater species of Glaucophyte that is used as a model organism. "C. paradoxa" has two cyanelles or chloroplasts where photosynthesis occurs. Cyanelles are unusual organelles in that they retain a rudimentary peptidoglycan wall. The cyanelle genome of "C. paradoxa" strain LB 555 was sequenced and published in 1995. The nuclear genome was also sequenced and published in 2012.
