Prochlorophytes features
Webb13 aug. 2004 · Our results clearly suggest that endosymbiotic cyanobacteria capable of fixing nitrogen are present in M. cavernosa and form a stable long-term association within host cells. This symbiont could potentially be a source of the limiting element nitrogen for the symbiosis through the release of fixed nitrogen products to the coral host. Fig. 3. WebbMore recently it has been found that prochlorophytes occur in the marine plankton. Prochlorophytes comprise a group of oxygenic photosynthetic cyanobacteria known for their photosynthetic pigments. They lack phycobilins, but have unusual chlorophylls (divinyl chlorophylls a and b ). Prochlorococcus cells are small – about the size of the ...
