Flow cytometry methods for targeted isolation of ctenophore cells

Frontiers in Marine Science, 2023
Cell suspension fluidics, such as flow cytometry (FCS) and fluorescence-activated cell sorting (FACS), facilitates the identification and precise separation of individual cells based on phenotype.

Morphological and dietary changes encoded in the genome of Beroe ovata, a ctenophore-eating ctenophore. [PDF]

NAR Genom Bioinform
Abstract As the sister group to all other animals, ctenophores (comb jellies) are important for understanding the emergence and diversification of numerous animal traits. Efforts to explore the evolutionary processes that promoted diversification within Ctenophora are hindered by undersampling genomic diversity within this clade.

Quantifying the feeding behavior and trophic impact of a widespread oceanic ctenophore

Scientific Reports, 2023
Oceanic ctenophores are widespread predators on pelagic zooplankton. While data on coastal ctenophores often show strong top-down predatory impacts in their ecosystems, differing morphologies, prey capture mechanisms and behaviors of oceanic species ...

Conserved novel ORFs in the mitochondrial genome of the ctenophore Beroe forskalii [PDF]

PeerJ, 2020
To date, five ctenophore species’ mitochondrial genomes have been sequenced, and each contains open reading frames (ORFs) that if translated have no identifiable orthologs. ORFs with no identifiable orthologs are called unidentified reading frames (URFs).

Cortical cytasters: a highly conserved developmental trait of Bilateria with similarities to Ctenophora

EvoDevo, 2011
Background Cytasters (cytoplasmic asters) are centriole-based nucleation centers of microtubule polymerization that are observable in large numbers in the cortical cytoplasm of the egg and zygote of bilaterian organisms.

Improved histological fixation of gelatinous marine invertebrates

Frontiers in Zoology, 2021
Background Gelatinous zooplankton can be difficult to preserve morphologically due to unique physical properties of their cellular and acellular components.

Nuclear receptors from the ctenophore Mnemiopsis leidyi lack a zinc-finger DNA-binding domain: lineage-specific loss or ancestral condition in the emergence of the nuclear receptor superfamily?

EvoDevo, 2011
Background Nuclear receptors (NRs) are an ancient superfamily of metazoan transcription factors that play critical roles in regulation of reproduction, development, and energetic homeostasis.

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]

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

Animal Phylogeny : Resolving the Slugfest of Ctenophores, Sponges and Acoels?

, 2021
Animal phylogeny has always been controversial, but a new study brings some much-needed order for two infamous wandering groups, the ctenophores and the Xenacoelomorphs.
