The enigmatic Placozoa part 1: Exploring evolutionary controversies and poor ecological knowledge
BioEssays, Volume 43, Issue 10, October 2021., 2021 Placozoans are the simplest and maybe the first branching metazoans. Their simple body plan and their small genome with a complex genetic tool kit make them important model systems. Substantial progress has been made in many areas, but many exciting questions on placozoan biology are still waiting to be addressed.

Placozoan fiber cells: mediators of innate immunity and participants in wound healing
Scientific Reports, 2021 Placozoa is a phylum of non-bilaterian marine animals. These small, flat organisms adhere to the substrate via their densely ciliated ventral epithelium, which mediates mucociliary locomotion and nutrient uptake.

Growth produces coordination trade-offs in Trichoplax adhaerens, an animal lacking a central nervous system [PDF]
, 2023 How collectives remain coordinated as they grow in size is a fundamental challenge affecting systems ranging from biofilms to governments. This challenge is particularly apparent in multicellular organisms, where coordination among a vast number of cells

Genome-wide analysis of transposable elements and tandem repeats in the compact placozoan genome
Biology Direct, 2010 The placozoan Trichoplax adhaerens has a compact genome with many primitive eumetazoan characteristics. In order to gain a better understanding of its genome architecture, we conducted a detailed analysis of repeat content in this genome.

Evolution of the perlecan/HSPG2 gene and its activation in regenerating Nematostella vectensis. [PDF]
PLoS ONE, 2015 The heparan sulfate proteoglycan 2 (HSPG2)/perlecan gene is ancient and conserved in all triploblastic species. Its presence maintains critical cell boundaries in tissue and its large (up to ~900 kDa) modular structure has prompted speculation about the ...

Non-coding RNA annotation of the genome of Trichoplax adhaerens [PDF]
, 2019 A detailed annotation of non-protein coding RNAs is typically missing in initial releases of newly sequenced genomes. Here we report on a comprehensive ncRNA annotation of the genome of Trichoplax adhaerens, the presumably most basal metazoan whose ...

Deep RNA sequencing reveals the smallest known mitochondrial micro exon in animals: The placozoan cox1 single base pair exon. [PDF]
PLoS ONE, 2017 The phylum Placozoa holds a key position for our understanding of the evolution of mitochondrial genomes in Metazoa. Placozoans possess large mitochondrial genomes which harbor several remarkable characteristics such as a fragmented cox1 gene and trans ...

Comparative genomics of large mitochondria in placozoans.
PLoS 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.

Comparative genomics of neuroglobin reveals its early origins. [PDF]
PLoS ONE, 2012 Neuroglobin (Ngb) is a hexacoordinated globin expressed mainly in the central and peripheral nervous system of vertebrates. Although several hypotheses have been put forward regarding the role of neuroglobin, its definite function remains uncertain.
