Millepora alcicornis is not a true coral in class Anthozoa but is in class Hydrozoa, and is more closely related to jellyfish than stony corals.
Except for two group I introns specifically harbored by coral species (classes Co1 and Co2), all the cox1 group I introns belong to Pcls previously defined by representatives from the fungal kingdom.
However, this view changed with the discovery of GFP-like proteins in non-luminescent organisms such as corals (Phylum Cnidaria, class Anthozoa), as well as representatives of other phyla: copepods (phylum Arthropoda, class Crustacea), and amphioxus (phylum Chordata, subphylum Cephalochordata) [6], [7], [8], [9], [10], [11], [12].
Soft corals (phylum Cnidaria, class Anthozoa, subclass Octocorallia, order Alcyonacea) often equal or exceed the total coverage of scleractinian corals in coral reef ecosystems [1, 2, 3, 4].
The biosynthesis of PGs in various organisms, such as mammals, corals, florideae (a class of red algae), yeast, and fungi, is also introduced.
A total of 104 species of anemones and corals (Phylum Cnidaria, Class Anthozoa) were present, with 2 Orders being prevalent across all sub-regions (Table 11).
Corals (Phylum Cnidaria, Class Anthozoa, Order Scleractinia) are among the many taxa for which we have no information on the population-level variability of immunity genes.
To better understand both the evolution of the Sox family and the roles of these genes in cnidarians, we are studying the Sox gene complement of the coral, Acropora millepora (Class Anthozoa).
The lack of effects from bottom type and depth class on coral assemblages among sites suggests that either: 1) replication was insufficient, or 2) other factors not examined here are structuring the species composition.
Size-frequency data indicated that species which were particularly affected by high abundances of macroalgae outside the reserve had a population bottleneck restricting the supply of smaller corals to larger size classes.
