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.

 TAXONOMY   (Site not responding. Last check: 2007-10-16)
One is Florideophyceae and the other is Bangiophyceae.
Bangiophyceae members are uninucleate cells, with intercalary cell division.
Since Corallina vancouveriensis does not fit in the Bangiophyceae class, because it has pit connections, apical growth and a triphasic life cycle, it is in the Florideophyceae class.

 RHODOTISTA
In this system, the red algae are divided into two major groups, Bangiologia ("Bangiophyceae") and Florideologia ("Florideophyceae").
Garbary and Gabrielson (1990) question the need of dividing the red algae into two groups and prefer to lump all of the orders into a single class.
(1990) do not consider the "Bangiophyceae" to be a monophyletic group.

Typically, apical cell divisions and coordinated development in the filaments produce a characteristic morphology in the pseudoparenchymatous plant.
Taxonomy The Rhodophyta are divided into two subclasses, the Bangiophyceae and the Florideophyceae.
An important distinction is that all Bangiophyceae are parenchymatous, while the Florideophyceae are pseudoparenchymatous.

In addition, WILMOTTE and DEMOULIN (1988) showed the influence of pollution on the distribution and ecology of some epiphytic Cyanophyceae.
GOFFART (1982), LAMPROYE (1984) and DETIENNE (1988) studied the distribution of the Bangiophyceae in the bay of Revellata (near the bay of Calvi).

Polyphosphate and siliceous granules in the macroscopic gametophytes of the red alga Porphyra purpurea (Bangiophyceae, Rhodophyta)
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 pulse-enriched seawater (15 µM phosphorus and 25 µM 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 acid-soluble and acid-insoluble polyphosphates are less significant as storage pools.

 Rhodophyta
Traditionally the red algae were divided into two Classes the Bangiophyceae and Florideophyceae.
Alternatively a single Class, the Rhodophyceae and two Subclasses, Bangiophycidae and Florideophycidae are used.
Based on ultrastructure and molecular evidence the Bangiophyceae is now accepted as a paraphyletic group, while the Florideophyceae is considered to be monophyletic based on two synapomorphic characters - presence of a filamentous gonimoblast and tetrasporangia (Garbary & Gabrielson 1990 [and references within], Ragan et al.

 Systematics for Porphyra lanceolata
It is perennial, meaning that it can be found growing year round.
Porphyra lanceolata fits under the Class Bangiophycea because it has a membranous thallus, uninucleate cells, stellate chloroplast, no cells with flagella, and reproduction by sporelike cells that are cut off singly from vegetative cells.
Porphyra lanceolata belongs to the Order Bangiales because the thallus is bladelike, it has gelatinous walls and the cells are not widely separated, it has no cells with flagella, asexual reproduction by monospores, and sexual reproduction.
