The development of bioluminescence in the ctenophore Mnemiopsis leidyi

Developmental Biology, 1973
Abstract The photocytes of the ctenophore Mnemiopsis have a discontinuous distribution along the radial canal between the sites where the comb plate cilia cells are located on the side of the canal which contains the testes. They are separated from the lumen of the canal by a population of gastric cells. Cytologically these cells are characterized by

leidyi Is a New Group of DD41D Transposons in Mnemiopsis leidyi Genome

Russian Journal of Genetics, 2019
The IS630/Tc1/mariner superfamily of transposable elements (TE) is one of the most numerous and widespread among DNA transposons. The IS630/Tc1/mariner TE are divided into eight families: IS630, Tc1, mariner, pogo, maT, mosquito, plants, and rosa. The members of the rosa family (DD41D transposons) were allocated to a separate group relatively recently ...

Impact of a new invasive ctenophore (Mnemiopsis leidyi) on the zooplankton community of the Southern Caspian sea

open access: yesMarine Ecology, 2008
The invasive ctenophore Mnemiopsis leidyi (Agassiz), which was transported from the Black Sea into the Caspian Sea at the end of the 1990s, has negatively affected the ecosystem of the Caspian Sea.

Developmental expression of homeobox genes in the ctenophore Mnemiopsis leidyi

Development Genes and Evolution, 2008
Homeobox genes are a large family of genes that encode helix-turn-helix transcription factors that play fundamental roles in such developmental processes including body axis formation and cell specification. They have been found in a wide variety of organisms, from fungi to plants and animals, with some classes being specific to the Metazoa.

SYMMETRY AND REGULATION IN MNEMIOPSIS LEIDYI, AGASSIZ

The Biological Bulletin, 1937
The ctenophores, a group in which Mnemiopsis is included, are usu ally referred to as biradially symmetrical animals. By some they are believed to have primarily a radial symmetry. There is of course the idea of bilateral symmetry expressed in the term biradial. As one sees this animal swimming freely in water it does seem to possess a radial symmetry.

Feeding Rates of the Ctenophore, Mnemiopsis leidyi

Chesapeake Science, 1967
Rates of feeding by the ctenophoreMnemiopsis leidyi were measured in order to evaluate the importance of predation by ctenophores on populations of zooplankton. Copepods, mostlyAcartia tonsa, and ctenophores from the Patuxent River and the harbor at Solomons, Maryland, were used. Rates of feeding were correlated with the experimental containers and the

Characterization of the mitochondrial proteome in the ctenophore Mnemiopsis leidyi using MitoPredictor

2023
ii. Abstract Mitochondrial proteomes have been experimentally characterized for only a handful of animal species. However, the increasing availability of genomic and transcriptomic data allows one to infer mitochondrial proteins using computational tools.

Ultrastructure of the luminescent system of the ctenophore Mnemiopsis leidyi

Cell and Tissue Research, 1985
The photocytes and other endodermal cells composing the wall of the meridional canals of the comb-jelly, Mnemiopsis leidyi, were investigated by transmission electron microscopy. Although many of these cells possess distinctive features such as a ciliary apparatus, lysosome-like bodies or vacuoles, they share with photocytes the presence of a network ...

APICAL DOMINANCE AND POLARITY IN MNEMIOPSIS LEIDYI, AGASSIZ

The Biological Bulletin, 1936
The locomotion of Mnemiopsis leidyi, as it moves along with its oral end forward near the surface of the water, serves to demonstrate that this animal possesses a definite polarity. The forward movement is a continuous reaction and is interrupted only when the animal bumps into some definite obstruction.

The role of cleavage in the localization of developmental potential in the Ctenophore Mnemiopsis leidyi

Developmental Biology, 1976
Abstract This study defines the time period during which the cellular components that specify comb plates and photocytes become localized in different parts of blastomeres prior to their segregation to separate daughter cells. At the two-cell stage the factors which specify comb plates are localized at the aboral pole of the blastomeres. There is not
