A P2X receptor from the tardigrade species Hypsibius dujardini with fast kinetics and sensitivity to zinc and copper

open access: yesBMC Evolutionary Biology, 2009
Background Orthologs of the vertebrate ATP gated P2X channels have been identified in Dictyostelium and green algae, demonstrating that the emergence of ionotropic purinergic signalling was an early event in eukaryotic evolution.

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.

A cause for consilience: Utilizing multiple genomic data types to resolve problematic nodes within Arthropoda and Ecdysozoa [PDF]

open access: yes, 2012
A major turning point in the study of metazoan evolution was the recognition of the existence of the Ecdysozoa in 1997. This is a group of eight animal phyla (Nematoda, Nematomorpha, Loricifera, Kinorhyncha, Priapulida, Tardigrada, Onychophora and ...

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.

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

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.

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 mitochondrial genome of the onychophoran Opisthopatus cinctipes (Peripatopsidae) reflects the ancestral mitochondrial gene arrangement of Panarthropoda and Ecdysozoa

open access: yes, 2010
The ancestral genome composition in Onychophora (velvet worms) is unknown since only a single species of Peripatidae has been studied thus far, which shows a highly derived gene order with numerous translocated genes. Due to this lack of information from

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.
