Cyanophora paradoxa is a freshwater species of Glaucophyte that is used as a model organism.[3][4] C. paradoxa has two cyanelles or chloroplasts where photosynthesis occurs.[3] Cyanelles are unusual organelles in that they retain a rudimentary peptidoglycan wall.[5] The cyanelle genome of C. paradoxa strain LB 555 was sequenced and published in 1995.[4][6] The nuclear genome was also sequenced and published in 2012.[7]

Description

Cyanophora paradoxa is a unicellular organism with two flagella, attached near the tip of the cell. The cell body is about 7-15 μm long by 3-6 μm wide; it is roughly ovoid (egg-shaped) in shape, and is covered in ridges that outline triangular or crescent-shaped "fenestrations". Each cell generally has one or two cyanelles.[8]
