The genome sequences of glaucophytes are not available for comparison, except for the ATP/ADP translocase, which is reportedly present in the glaucophyte Cyanophora paradoxa [25] and was also identified in another glaucophyte Glaucocystis from the Taxonomically Broad EST Database (TBestDB). G, green plants; R, red algae.
