Spermatogenesis in anthozoa: Differentiation of the spermatid

Cell And Tissue Research, 1975
The fine structure of spermatids has been examined in Calliactis, Protanthea, Gonactinia and Parazoanthus (Cnidaria, Anthozoa). The sperm cells are relatively simple and lack distinct acrosomes. Their nuclei, spherical in the zoanthid, in the actinians are slendertipped cones. Condensation of the chromatin is interpreted in terms of progressive coiling

Systematic Relationships within the Anthozoa (Cnidaria: Anthozoa) Using the 5′-end of the 28S rDNA

Molecular Phylogenetics and Evolution, 1995
Systematic relationships among the subclasses of Anthozoa, and especially among the orders Scleractinia, Actiniaria, and Corallimorpharia of subclass Zoantharia, were investigated by applying parsimony and distance methods of analysis to nucleotide sequence data obtained for the 5' end of the 28S rDNA.

Anthozoa red fluorescent protein in biosensing

Analytical and Bioanalytical Chemistry, 2006
The identification and cloning of a red fluorescent protein (DsRed) obtained from Anthozoa corals has provided an alternative to commonly used green fluorescent proteins (GFPs) in bioanalytical and biomedical research. DsRed in tandem with GFPs has enhanced the feasibility of multicolor labeling studies.

Bacteria in the coelenteron of Anthozoa: Control of coelenteric bacterial density by the coelenteric fluid

Journal of Experimental Marine Biology and Ecology, 1985
Coelenteric bacterial densities of four Mediterranean anthozoan species, Parazoanthus axinellae (Schmidt), Anemonia sulcata (Pennant), Leptopsammia pruvoti (Lac.-Duth.), Cladocora cespitosa (L.) and one tropical species, Stoichactis giganteum (Forskal) were investigated in situ and under controlled laboratory conditions.

Generation of bilateral symmetry in Anthozoa: A model

Journal of Theoretical Biology, 2007
Polyps of Anthozoa usually display bilateral symmetry with respect to their mouth opening, to their pharynx, and in particular to the arrangement of their mesenteries. Mesenteries, which are endodermal folds running from the apical to the basal end of the body, subdivide the gastric cavity into pouches. They form in a bilateral symmetric sequence.

Fluorescent proteins from nonbioluminescent Anthozoa species

Nature Biotechnology, 1999
We have cloned six fluorescent proteins homologous to the green fluorescent protein (GFP) from Aequorea victoria. Two of these have spectral characteristics dramatically different from GFP, emitting at yellow and red wavelengths. All the proteins were isolated from nonbioluminescent reef corals, demonstrating that GFP-like proteins are not always ...

Colonial conduction systems in the Anthozoa: Octocorallia

Journal of Experimental Biology, 1975
ABSTRACT The octocorals Alcyonium digitatum, Pennatula phosphorea and Virgularía mirabilis each have a through-conducting nerve net. The nerve net demonstrated electrophysiologically may well be the same as that previously shown by the use of histological techniques.
