An EST screen from the annelid Pomatoceros lamarckii reveals patterns of gene loss and gain in animals [PDF]

BMC Evolutionary Biology, 2009
Background Since the drastic reorganisation of the phylogeny of the animal kingdom into three major clades of bilaterians; Ecdysozoa, Lophotrochozoa and Deuterostomia, it became glaringly obvious that the selection of model systems with extensive ...

Identification of proteins from the secretory/excretory products (SEPs) of the branchiuran ectoparasite Argulus foliaceus (Linnaeus, 1758) reveals unique secreted proteins amongst haematophagous ecdysozoa [PDF]

Parasites & Vectors, 2020
Background It is hypothesised that being a blood-feeding ectoparasite, Argulus foliaceus (Linnaeus, 1758), uses similar mechanisms for digestion and host immune evasion to those used by other haematophagous ecdysozoa, including caligid copepods (e.g. sea

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

Genes, 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 ...

The presence of alpha-chitin in Tardigrada with comments on chitin in the Ecdysozoa

Zoologischer Anzeiger - A Journal of Comparative Zoology, 2016
WOS: 000383823700002We used Fourier Transform Infrared Spectroscopy (FT-IR) to characterize for the first time chitin in the cuticle of a eutardigrade (Macrobiotus cf. hufelandi).

The Ediacaran origin of Ecdysozoa:integrating fossil and phylogenomic data [PDF]

Journal of the Geological Society, 2022
Ecdysozoans (Phyla Arthropoda, Kinorhyncha, Loricifera, Nematoda, Nematomorpha, Onychophora, Priapulida, Tardigrada) are invertebrates bearing a tough, periodically moulted cuticle that predisposes them to exceptional preservation.

The genome sequence of the Montseny horsehair worm, Gordionus montsenyensis sp. nov., a key resource to investigate Ecdysozoa evolution [PDF]

Peer Community Journal
Nematomorpha, also known as Gordiacea or Gordian worms, are a phylum of parasitic organisms that belong to the Ecdysozoa, a clade of invertebrate animals characterized by molting.

An ancient anterior patterning system promotes Caudal repression and head formation in Ecdysozoa. [PDF]

Current Biology, 2009
SummaryPosterior expression of Caudal is required for early embryonic development in nematodes, arthropods, and vertebrates [1–9]. In Drosophila, ectopic Caudal in anterior cells can induce head defects, and in Caenorhabditis the absence of Caudal in ...

Multigene Analyses of Bilaterian Animals Corroborate the Monophyly of Ecdysozoa, Lophotrochozoa and Protostomia [PDF]

Molecular Biology and Evolution, 2005
International audienceAlmost a decade ago, a new phylogeny of bilaterian animals was inferred from small-subunit ribosomal RNA (rRNA) that claimed the monophyly of two major groups of protostome animals: Ecdysozoa (e.g., arthropods, nematodes, onycho ...

The Unique Antimicrobial Recognition and Signaling Pathways in Tardigrades with a Comparison Across Ecdysozoa [PDF]

G3: Genes, Genomes, Genetics, 2020
Tardigrades are microscopic animals known to withstand unfavorable abiotic conditions. These animals are also constantly exposed to biotic stresses, including parasites and internal microbiomes.

ParaHox Genes Revisited: From Gut Patterning to Integrated Axial and Neural Organization in Rotifera. [PDF]

J Exp Zool B Mol Dev Evol
In rotifers, ParaHox genes show a dispersed genomic organization, with Xlox absent across gnathiferans. Exclusive neuronal expression of Gsx and Cdx reveals that ancestral ParaHox genes coordinated neural and epithelial development beyond gut patterning, suggesting an integrated role in early bilaterian body plan organization.
