Gap Junctions in Ctenophora.

Methods in molecular biology
Gap junction proteins form specialized intercellular communication channels, including electrical synapses, that regulate cellular metabolism and signaling. We present a molecular inventory of the gap junction proteins-innexins (INX-like) in ctenophores, focusing on two reference species, Pleurobrachia bachei and Mnemiopsis leidyi.

Ctenophora: Illustrated Guide and Taxonomy.

Methods in molecular biology
Ctenophores or comb jellies represent the first diverging lineage of extant animals - sister to all other Metazoa. As a result, they occupy a unique place in the biological sciences. Despite their importance, this diverse group of marine predators has remained relatively poorly known, with both the species and higher-level taxonomy of the phylum in ...

The diatom genus Ctenophora: A discussion on its morphology, relationships, and some species

Phytotaxa, 2023
The diatom genus Ctenophora is examined for its morphological characters and its relationships. Some aspects of the nomenclature of the genus are clarified with respect to various specimens identified as Ctenophora pulchella, Ctenophora saxonica and ...

An electron microscope study and re-description of the type specimens of Synedra subula and its transfer to Ctenophora (Bacillariophyta)

Phytotaxa, 2023
Synedra subula Sande Lac. & Suringar is rarely encountered today. Although a reasonable description was provided, the species has never been illustrated.

Revision of Beroidae (Ctenophora) in the southern seas of Europe: systematics and distribution based on genetics and morphology

Zoological Journal of the Linnean Society, 2021
Genetic and morphological analyses were used to revise historical controversies in identities of Beroe species in the southern seas of Europe. DNA analyses with ITS sequences were used to explore their phylogenetic relationships. Three species of Beroe

Egg-laying in Ctenophora [PDF]

Nature, 1954
WHILE occupied with field-work on Siphonophora, I placed six small Pleurobrachia sp. measuring about 2.5 mm. in length in a watch-glass at 1100 hr. on April 29. An hour later I noticed that eggs were being extruded through the ectoderm over the gastrovascular canals. Since the fertilization membrane was present as the eggs were being extruded, it would

The impact of polychlorinated biphenyls on the bioluminescence rates of the Black Sea ctenophore Mnemiopsis leidyi A. Agassiz (Ctenophora: Lobata)

Monitoring systems of environment, 2021
The toxic impact of a mixture of polychlorinated biphenyls Aroclor 1254 (PCB) on the luminescence characteristics of the ctenophores Mnemiopsisleidyi A. Agassiz was studied.

Ctenophora

2017
This chapter describes the taxonomy of ctenophores. The ctenophores, or comb jellies, are gelatinous metazoans belonging to a small and entirely marine phylum of about 150 species. They are mostly planktonic, with the exception of the benthic order Platyctenida, where only the larvae are planktonic.
