Glaucophyta

UTEX 64 cultured on agar

Cyanophora paradoxa showing Cyanelles, nucleus and flagellae. Scale bar indicates 10 µm.  From algae culture of University Duisburg-Essen (Germany), pictures were taken with Zeiss Axioplan and Canon 600D.

Cyanophora (sigh-an-off-oar-a) paradoxa, often regarded as an enigmatic alga because it did not fall into any of the familiar groups. Photosynthesis occurs in the blue-green-colored cyanelles, endosymbiotic structures that appear to be an evolutionary intermediate between blue-green algae and chloroplasts. With two flagella inserting below the apex of the cell, one directed to the front and a longer one trailing. Differential interference microscopy. data on this strain.

Description: English: Membrane structre of a plant cell (glaucophyta). Plantae originated by primary enslavement of a cyanobacterium to make plastids. Cyanophora, from the earliest diverging plant phylum Glaucophyta.Plastid membrane structure is identical to cyanobacteria with thylakoids. The common ancestor of red algae and green plants (not shown) lost cortical alveoli (which grow by fusion of Golgi-derived vesicles), red algae and two green plant subgroups lost chloroplast envelope murein peptidoglycan, and green plants lost phycobilisomes and stack their thylakoids.
