Innate immunity in the simplest animals – placozoans

open access: yesBMC Genomics, 2019
Background Innate immunity provides the core recognition system in animals for preventing infection, but also plays an important role in managing the relationship between an animal host and its symbiont.

Rho Family of Ras-Like GTPases in Early-Branching Animals

open access: yesCells, 2020
Non-bilaterian animals consist of four phyla; Porifera, Cnidaria, Ctenophora, and Placozoa. These early-diverging animals are crucial for understanding the evolution of the entire animal lineage.

Bioeffects of Prunus spinosa L. fruit ethanol extract on reproduction and phenotypic plasticity of Trichoplax adhaerens Schulze, 1883 (Placozoa) [PDF]

open access: yesPeerJ, 2019
The aim of this work was to test and analyse the bioeffects of Prunus spinosa L. (Rosacaee) fruit ethanol extract on Trichoplax adhaerens Schulze, 1883 (Placozoa) laboratory cultures which—for the first time—were employed as in vivo biological model to ...

New insights into placozoan sexual reproduction and development.

open access: yesPLoS ONE, 2011
Unraveling animal life cycles and embryonic development is basic to understanding animal biology and often sheds light on phylogenetic relationships. A key group for understanding the evolution of the Metazoa is the early branching phylum Placozoa, which

Placozoa and Cnidaria are sister taxa

open access: yeseLife, 2017
Abstract The phylogenetic placement of the morphologically simple placozoans is crucial to understanding the evolution of complex animal traits. Here, we examine the influence of adding new genomes from placozoans to a large dataset designed to study the deepest splits in the animal phylogeny.

Apicortin, a Constituent of Apicomplexan Conoid/Apical Complex and Its Tentative Role in Pathogen—Host Interaction

open access: yesTropical Medicine and Infectious Disease, 2021
In 2009, apicortin was identified in silico as a characteristic protein of apicomplexans that also occurs in the placozoa, Trichoplax adhaerens. Since then, it has been found that apicortin also occurs in free-living cousins of apicomplexans (chromerids)

Placozoa Are Not Derived Cnidarians: Evidence from Molecular Morphology [PDF]

open access: yesMolecular Biology and Evolution, 2003
The phylum Placozoa is represented by a single known species, Trichoplax adhaerens, a tiny marine organism that represents the most simple metazoan bauplan. Because of the latter, placozoans were originally considered the most basal metazoan phylum.

Let’s end taxonomic blank slates with molecular morphology

open access: yesFrontiers in Ecology and Evolution, 2022
Many known evolutionary lineages have yet to be described formally due to a lack of traditional morphological characters. This is true for genetically distinctive groups within the amoeboid Placozoa animals, the protists in ponds, and the bacteria that ...

New genomic data and analyses challenge the traditional vision of animal epithelium evolution

open access: yesBMC Genomics, 2018
Background The emergence of epithelia was the foundation of metazoan expansion. Epithelial tissues are a hallmark of metazoans deeply rooted in the evolution of their complex developmental morphogenesis processes.

Exploring Mesophotic Coral Reef Boundaries Using Environmental DNA Metabarcoding

open access: yesEnvironmental DNA, Volume 8, Issue 4, July‐August 2026.
Environmental DNA (eDNA) metabarcoding reveals boundaries along depth gradients in shallow and mesophotic coral reefs. Analysis of metazoan amplicon sequence variants (ASVs) uncovers changes in community structure from shallow to deep reefs, highlighting a localized eDNA footprint and its potential for monitoring mesophotic and deep‐sea habitats ...
