Arthropod Phylogenetics in Light of Three Novel Millipede (Myriapoda: Diplopoda) Mitochondrial Genomes with Comments on the Appropriateness of Mitochondrial Genome Sequence Data for Inferring Deep Level Relationships [PDF]

, 2013
Background Arthropods are the most diverse group of eukaryotic organisms, but their phylogenetic relationships are poorly understood. Herein, we describe three mitochondrial genomes representing orders of millipedes for which complete genomes had not ...

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

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 ...

The development of the larval nervous system, musculature and ciliary bands of Pomatoceros lamarckii (Annelida): heterochrony in polychaetes

Frontiers in Zoology, 2006
Background To understand the evolution of animals it is essential to have taxon sampling across a representative spread of the animal kingdom. With the recent rearrangement of most of the Bilateria into three major clades (Ecdysozoa, Lophotrochozoa and ...

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

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

Growth and Maintenance of Wolbachia in Insect Cell Lines

Insects, 2021
The obligate intracellular microbe, Wolbachia pipientis (Rickettsiales; Anaplasmataceae), is a Gram-negative member of the alpha proteobacteria that infects arthropods and filarial worms.

Rare Coding Sequence Changes are Consistent with Ecdysozoa, not Coelomata [PDF]

Molecular Biology and Evolution, 2007
There is growing interest in the use of alternative, more slowly-evolving RGCs (rare genomic changes). Recently, Rogozin and coauthors (Rogozin et al. 2007) proposed a novel phylogenetic method employing rare amino acid changes, RGC-CAMs (rare genomic changes-conserved amino acids-multiple substitutions).

The Ecdysozoa: Artifact or monophylum?

Journal of Zoological Systematics and Evolutionary Research, 2009
The molecular support for the recently postulated hypothesis ‘Ecdysozoa’ is re-examined. Some 18S rDNA-alignments clearly contain a pattern of character states that cause tree building methods to identify a clade comprised of arthropods and Cycloneuralia.

Coelomata and Not Ecdysozoa: Evidence From Genome-Wide Phylogenetic Analysis [PDF]

Genome Research, 2004
Relative positions of nematodes, arthropods, and chordates in animal phylogeny remain uncertain. The traditional tree topology joins arthropods with chordates in a coelomate clade, whereas nematodes, which lack a coelome, occupy a basal position. However, the current leading hypothesis, based on phylogenetic trees for 18S ribosomal RNA and several ...

Xenoturbella bocki exhibits direct development with similarities to Acoelomorpha [PDF]

, 2013
Xenoturbella bocki, a marine animal with a simple body plan, has recently been suggested to be sister group to the Acoelomorpha, together forming the new phylum Xenacoelomorpha.
