Venomous Noodles: The Evolution of Toxins in Nemertea through Positive Selection and Gene Duplication [PDF]

Toxins, 2023
Some, probably most and perhaps all, members of the phylum Nemertea are poisonous, documented so far from marine and benthic specimens. Although the toxicity of these animals has been long known, systematic studies on the characterization of toxins ...

Characterization of the complete mitochondrial genome of Quasilineus sinicus Gibson, 1990 (Nemertea: Heteronemertea) and its phylogenetic implications [PDF]

Mitochondrial DNA. Part B. Resources, 2022
In this study, we sequenced and characterized the complete mitochondrial genome (mitogenome) of Quasilineus sinicus Gibson, 1990 (Heteronemertea, Nemertea) using Illumina sequencing technology.

ERGA-BGE reference genome of the lineid heteronemertean Lineus lacteus (Pilidiophora, Nemertea) [version 2; peer review: 2 approved] [PDF]

Open Research Europe
The reference genome of Lineus lacteus is a crucial resource for studying the genetic basis of novelty and the evolution of remarkable traits, such as regeneration and venom, as well as the molecular mechanisms underlying adaptability in marine ...

The genome sequence of the bootlace worm, Lineus longissimus (Gunnerus, 1770) [version 1; peer review: 2 approved] [PDF]

Wellcome Open Research, 2021
We present a genome assembly from an individual Lineus longissimus (the bootlace worm; Nemertea; Pilidiophora; Heteronemertea; Lineidae). The genome sequence is 391 megabases in span.

Proteotranscriptomic Profiling of the Toxic Mucus of Kulikovia alborostrata (Pilidiophora, Nemertea) [PDF]

Toxins
Nemertea is a phylum of bilaterally symmetrical, coelomate, unsegmented worms, also known as ribbon worms. Most species of the phylum Nemertea are marine predators that contain toxins in the single-celled glands of the proboscis and/or integument. Recent

Comparative development of the serotonin- and FMRFamide-immunoreactive components of the nervous system in two distantly related ribbon worm species (Nemertea, Spiralia) [PDF]

Frontiers in Neuroscience
IntroductionNeurodevelopment in larval stages of non-model organisms, with a focus on the serotonin- and FMRFamide-immunoreactive components, has been in the focus of research in the recent past.

Statistical Parsimony Networks and Species Assemblages in Cephalotrichid Nemerteans (Nemertea) [PDF]

PLoS ONE, 2010
BACKGROUND: It has been suggested that statistical parsimony network analysis could be used to get an indication of species represented in a set of nucleotide data, and the approach has been used to discuss species boundaries in some taxa.

Microbiota Associated With Ototyphlonemertes Species (Nemertea, Hoplonemertea, Monostilifera, Ototyphlonemertidae) Reveal Evidence of Phylosymbiosis [PDF]

Ecology and Evolution
Phylosymbiosis, the association between the phylogenetic relatedness of hosts and the composition of their microbial communities, is a widespread phenomenon in diverse animal taxa.

The nervous systems of basally branching nemertea (palaeonemertea). [PDF]

PLoS ONE, 2013
In recent years, a lot of studies have been published dealing with the anatomy of the nervous system in different spiralian species. The only nemertean species investigated in this context probably shows derived characters and thus the conditions found ...

A hundred species, mostly new—first assessment of ribbon worm diversity and distribution in Oman [PDF]

PeerJ
Background Biodiversity is a key characteristic of any ecosystem but remains largely undescribed for most marine animals. Ribbon worms (phylum Nemertea), a diverse but poorly sampled phylum ubiquitous in the world’s oceans, are a case in point.
