Bangiophyceae is a class of Red algae. Red algae Classes Florideophyceae Bangiophyceae Cyanidiophyceae The red algae (Rhodophyta) are a large group of mostly multicellular, marine algae, including many notable seaweeds. ...
Phosphorylated fractions in tissues of starved and fresh plants of Porphyra purpurea, a representative of the Bangiophyceae, were analyzed over a 48 h incubation period in pulseenriched seawater (15 muM phosphorus and 25 muM nitrogen).
Compared to Chondrus crispus, a representative of the structurally and reproductively more complex Florideophyceae, P. purpurea takes up phosphorus much more actively, with a higher turnover rate, in which the orthophosphate fraction is predominant and acidsoluble and acidinsoluble polyphosphates are less significant as storage pools.
To our knowledge, this is the first report in algae of such structures whose occurrence and metabolic role remain enigmatic.
The Bangiophyceae are the most diverse group within the Rhodophyta as far as evolutionary aspects are considered.
Their taxonomic identification is problematic due to the lack of distinct morphological features (unicellular, multicellular filaments, sheet-like thalli) and the presumed morphological plasticity of the species.
The ecological importance of the Bangiophyceae in the Baltic Sea will be assessed and their geographical distribution limits will be deduced.
