The early ANTP gene repertoire: insights from the placozoan genome. [PDF]

open access: yesPLoS ONE, 2008
The evolution of ANTP genes in the Metazoa has been the subject of conflicting hypotheses derived from full or partial gene sequences and genomic organization in higher animals.

An evaluation of the evolution of the gene structure of dystroglycan [PDF]

open access: yes, 2017
BACKGROUND: Dystroglycan (DG) is an adhesion receptor complex composed of two non-covalently associated subunits, transcribed from a single gene. The extracellular α-DG is highly and heterogeneously glycosylated and binds with high affinity to laminins ...

Comparative genomics of large mitochondria in placozoans.

open access: yesPLoS Genetics, 2007
The first sequenced mitochondrial genome of a placozoan, Trichoplax adhaerens, challenged the conventional wisdom that a compact mitochondrial genome is a common feature among all animals.

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.

Multiple surveys employing a new sample‐processing protocol reveal the genetic diversity of placozoans in Japan [PDF]

open access: yes, 2018
Placozoans, flat free‐living marine invertebrates, possess an extremely simple bauplan lacking neurons and muscle cells and represent one of the earliest‐branching metazoan phyla. They are widely distributed from temperate to tropical oceans.

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 ...

Mathematical modeling and comparison of protein size distribution in different plant, animal, fungal and microbial species reveals a negative correlation between protein size and protein number, thus providing insight into the evolution of proteomes [PDF]

open access: yes, 2012
Background The sizes of proteins are relevant to their biochemical structure and for their biological function. The statistical distribution of protein lengths across a diverse set of taxa can provide hints about the evolution of proteomes. Results Using

Hidden cell diversity in Placozoa: ultrastructural insights from Hoilungia hongkongensis [PDF]

open access: yesCell and Tissue Research, 2020
AbstractFrom a morphological point of view, placozoans are among the most simple free-living animals. This enigmatic phylum is critical for our understanding of the evolution of animals and their cell types. Their millimeter-sized, disc-like bodies consist of only three cell layers that are shaped by roughly six major cell types. Placozoans lack muscle

The evolution of metazoan extracellular matrix [PDF]

open access: yes, 2011
The modular domain structure of extracellular matrix (ECM) proteins and their genes has allowed extensive exon/domain shuffling during evolution to generate hundreds of ECM proteins.
