β-Catenin localization in the ctenophore Mnemiopsis leidyi suggests an ancestral role in cell adhesion and nuclear function. [PDF]

Dev Dyn
Abstract Background The emergence of multicellularity in animals marks a pivotal evolutionary event, which was likely enabled by molecular innovations in the way cells adhere and communicate with one another. β‐Catenin is significant to this transition due to its dual role as both a structural component in the cadherin–catenin complex and as a ...

Reverse development in the ctenophore <i>Mnemiopsis leidyi</i>. [PDF]

Proc Natl Acad Sci U S A
Reverse development, or the ability to rejuvenate by morphological reorganization into the preceding life cycle stage is thought to be restricted to a few species within Cnidaria. To date, Turritopsis dohrnii is the only known species capable of undergoing reverse development after the onset ...

Studying Ctenophora WBR Using Mnemiopsis leidyi

Cold Spring Harbor Protocols, 2022
AbstractCtenophores, also known as comb jellies, are a clade of fragile holopelagic, carnivorous marine invertebrates, that represent one of the most ancient extant groups of multicellular animals. Ctenophores show a remarkable ability to regenerate in the adult form, being capable of replacing all body parts (i.e., whole-body regeneration) after loss ...

An AI-generated proteome-scale dataset of predicted protein structures for the ctenophore Mnemiopsis leidyi. [PDF]

Proteomics
Abstract This Dataset Brief describes the computational prediction of protein structures for the ctenophore Mnemiopsis leidyi. Here, we report the proteome‐scale generation of 15,333 protein structure predictions using AlphaFold, as well as an updated implementation of publicly available search, manipulation, and visualization tools for these protein ...

Evolution of the TGF-β signaling pathway and its potential role in the ctenophore, Mnemiopsis leidyi. [PDF]

PLoS ONE, 2011
The TGF-β signaling pathway is a metazoan-specific intercellular signaling pathway known to be important in many developmental and cellular processes in a wide variety of animals. We investigated the complexity and possible functions of this pathway in a

Hidden aliens: Application of digital PCR to track an exotic foraminifer across the Skagerrak (North Sea) correlates well with traditional morphospecies analysis

Environmental Microbiology, Volume 25, Issue 11, Page 2321-2337, November 2023., 2023
This study reports for the first‐time the application of a digital PCR (dPCR) assay to target an alien species of a free‐living unicellular non‐pathogenic Eukaryote belonging to Foraminifera (Rhizaria). The number of DNA copies from our species‐specific dPCR assay highly correlates with morphospecies counts thus picking up the DNA signal from organisms

Multi‐year time series reveals temporally synchronous diatom communities with annual frequency of recurrence in a temperate estuary

Limnology and Oceanography, Volume 68, Issue 9, Page 1982-1994, September 2023., 2023
Abstract Diatoms are among the most abundant phytoplankton that inhabit coastal ecosystems, forming large blooms that fuel coastal food webs. Although diatoms are often large and morphologically distinct, many are small or morphologically cryptic making it difficult to understand the temporal dynamics of whole diatom communities and the environmental ...
