The sex lives of ctenophores: the influence of light, body size, and self-fertilization on the reproductive output of the sea walnut, Mnemiopsis leidyi [PDF]

open access: yesPeerJ, 2016
Ctenophores (comb jellies) are emerging as important animals for investigating fundamental questions across numerous branches of biology (e.g., evodevo, neuroscience and biogeography).

Genomic signatures of speciation and adaptation in the ctenophore Mnemiopsis [PDF]

open access: yesBMC Biology
Background Understanding how populations diverge is one of the most compelling questions in evolutionary biology but our grasp on the genomic mechanisms underpinning divergence is limited to a handful of species.

Stimulated bacterioplankton growth and selection for certain bacterial taxa in the vicinity of the ctenophore Mnemiopsis leidyi

open access: yesFrontiers in Microbiology, 2012
Episodic blooms of voracious gelatinous zooplankton, such as the ctenophore Mnemiopsis leidyi, affect pools of inorganic nutrients and dissolved organic carbon by intensive grazing activities and mucus release.

Par protein localization during the early development of Mnemiopsis leidyi suggests different modes of epithelial organization in the metazoa [PDF]

open access: yeseLife, 2020
In bilaterians and cnidarians, epithelial cell-polarity is regulated by the interactions between Par proteins, Wnt/PCP signaling pathway, and cell-cell adhesion. Par proteins are highly conserved across Metazoa, including ctenophores.

Organization of the ctenophore tentacular apparatus: Adult <i>Mnemiopsis leidyi</i> lacks a canonical principal tentacle. [PDF]

open access: yesiScience
Summary Ctenophores represent one of the earliest-diverging animal lineages and are distinguished by their exceptional feeding efficiency. The tentacular apparatus of Mnemiopsis leidyi mediates feeding and likely serves diverse sensory roles, yet its ...

The ctenophore Mnemiopsis leidyi regulates egg production via conspecific communication [PDF]

open access: yesBMC Ecology, 2018
Background Communication between individuals of the same species is an important aspect of mating and reproduction in most animals. In simultaneously hermaphroditic species with the ability to self-fertilize, communication with conspecifics can be ...

MicroRNAs and essential components of the microRNA processing machinery are not encoded in the genome of the ctenophore Mnemiopsis leidyi [PDF]

open access: yesBMC Genomics, 2012
Background MicroRNAs play a vital role in the regulation of gene expression and have been identified in every animal with a sequenced genome examined thus far, except for the placozoan Trichoplax. The genomic repertoires of metazoan microRNAs have become

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

open access: yesbioRxiv, 2023
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 ...
