Analysis of the immune-related transcriptome of a lophotrochozoan model, the marine annelid Platynereis dumerilii

open access: yesFrontiers in Zoology, 2007
Background The marine annelid Platynereis dumerilii (Polychaeta, Nereididae) has been recognized as a slow-evolving lophotrochozoan that attracts increasing attention as a valuable model for evolutionary and developmental research.

Bringing together but staying apart: decisive differences in animal and fungal mitochondrial inner membrane fusion

open access: yesBiological Reviews, Volume 100, Issue 2, Page 920-935, April 2025.
ABSTRACT Mitochondria are dynamic and plastic, undergoing continuous fission and fusion and rearrangement of their bioenergetic sub‐compartments called cristae. These fascinating processes are best understood in animal and fungal models, which are taxonomically grouped together in the expansive Opisthokonta supergroup.

Slit-Robo expression in the leech nervous system: insights into eyespot evolution

open access: yesCell & Bioscience, 2023
Background Slit and Robo are evolutionarily conserved ligand and receptor proteins, respectively, but the number of slit and robo gene paralogs varies across recent bilaterian genomes.

An Ancient Anterior Patterning System Promotes Caudal Repression and Head Formation in Ecdysozoa [PDF]

open access: yesCurrent Biology, 2009
Posterior expression of Caudal is required for early embryonic development in nematodes, arthropods, and vertebrates. In Drosophila, ectopic Caudal in anterior cells can induce head defects, and in Caenorhabditis the absence of Caudal in anterior embryonic cells is required for proper development. Anterior Caudal repression in these species is achieved

Hepatincolaceae (Alphaproteobacteria) are Distinct From Holosporales and Independently Evolved to Associate With Ecdysozoa

open access: yesEnvironmental Microbiology, Volume 27, Issue 1, January 2025.
The main differences between the ‘Ca. Hepatincolaceae’ and the Holosporales are their habitats and modes of existence. The former are non‐motile bacteria that exist extracellularly in the host gut lumen, associating with microvilli, while the latter are intracellular bacteria, primarily hosted by protists such as amoebae and ciliates, and often possess

Pigment Dispersing Factors and Their Cognate Receptors in a Crustacean Model, With New Insights Into Distinct Neurons and Their Functions

open access: yesFrontiers in Neuroscience, 2020
Pigment dispersing factors (PDFs, or PDHs in crustaceans) form a structurally related group of neuropeptides found throughout the Ecdysozoa and were first discovered as pigmentary effector hormones in crustaceans.

Breakdown of coevolution between symbiotic bacteria Wolbachia and their filarial hosts [PDF]

open access: yesPeerJ, 2016
Wolbachia is an alpha-proteobacterial symbiont widely distributed in arthropods. Since the identification of Wolbachia in certain animal-parasitic nematodes (the Onchocercidae or filariae), the relationship between arthropod and nematode Wolbachia has ...

An Orthologue of the Retinoic Acid Receptor (RAR) Is Present in the Ecdysozoa Phylum Priapulida [PDF]

open access: yesGenes, 2019
Signalling molecules and their cognate receptors are central components of the Metazoa endocrine system. Defining their presence or absence in extant animal lineages is critical to accurately devise evolutionary patterns, physiological shifts and the impact of endocrine disrupting chemicals.

A peritidal Burgess‐Shale‐type fauna from the middle Cambrian of western Canada

open access: yesPalaeontology, Volume 68, Issue 1, January/February 2025.
Abstract Burgess‐Shale‐type (BST) faunas have proven critical for mapping the Cambrian assembly of animal‐dominated ecosystems, but have so far only been reported from fully subaqueous deposits. Here we integrate evidence from ichnofossils, sedimentary features, and small carbonaceous fossils (SCFs) from the middle Cambrian (Late Guzhangian, Series 3 ...

The genome sequence of the Rose Chafer, Cetonia aurata (Linnaeus, 1758) [version 2; peer review: 2 approved, 1 approved with reservations]

open access: yesWellcome Open Research
We present a genome assembly from an individual male Cetonia aurata (the Rose Chafer; Arthropoda; Insecta; Coleoptera; Scarabaeidae). The genome sequence is 479.6 megabases in span.
