Review: The evolution of peptidergic signaling in Cnidaria and Placozoa, including a comparison with Bilateria

Frontiers in Endocrinology, 2022
Bilateria have bilateral symmetry and are subdivided into Deuterostomia (animals like vertebrates) and Protostomia (animals like insects and mollusks).

Global Habitat Suitability and Ecological Niche Separation in the Phylum Placozoa. [PDF]

PLoS ONE, 2015
The enigmatic placozoans, which hold a key position in the metazoan Tree of Life, have attracted substantial attention in many areas of biological and biomedical research.

Investigations of the Evolved Molecular Basis for Terpenoid Biosynthesis in Marine Sponges. [PDF]

Adv Sci (Weinh)
Confirming and extending a previous observation in another Bubarida sponge, genomic and functional analyses of A. cavernosa reveal that sponges retain the mevalonate pathway and employ single α‐domain T1TSs and UbiA‐type TSs for terpenoid biosynthesis. The absence of T1TSs clustering with other biosynthetic genes tentatively suggests, based on limited ...

Transposon-derived transcription factors across metazoans

Frontiers in Cell and Developmental Biology, 2023
Transposable elements (TE) could serve as sources of new transcription factors (TFs) in plants and some other model species, but such evidence is lacking for most animal lineages. Here, we discovered multiple independent co-options of TEs to generate 788

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 ...

Alternative neural systems: What is a neuron? (Ctenophores, sponges and placozoans)

Frontiers in Cell and Developmental Biology, 2022
How to make a neuron, a synapse, and a neural circuit? Is there only one ‘design’ for a neural architecture with a universally shared genomic blueprint across species?

Comparative Multi-Marker Environmental DNA Metabarcoding of Marine Metazoan Communities: Water vs. Sediment. [PDF]

Mol Ecol Resour
ABSTRACT This study investigates the metazoan biodiversity in the Southern Adriatic Sea using environmental DNA (eDNA) metabarcoding. Sediment and adjacent water samples were collected from three sites (one pristine, two impacted by human activities) at three distances from the coast across two seasons.

Phylogenetic position of Placozoa based on large subunit (LSU) and small subunit (SSU) rRNA genes

Genetics and Molecular Biology, 2007
The phylum Placozoa, represented by its single species Trichoplax adhaerens, has always been considered one of the most basal animal clades due to its low morphological complexity.

Metagenomic Insights Into Red Sea Biodiversity Across the Web of Life. [PDF]

Environ Microbiol
Deep‐sequencing shotgun metagenomics of Red Sea benthic sediments reveals biodiversity across the web of life, from viruses to animals. Despite the strong dominance of prokaryotic DNA, low‐abundance eukaryotic reads capture broad taxonomic diversity. Open‐ocean communities are primarily structured by depth, whereas coastal eukaryotic communities follow

Molecular signatures for sex in the Placozoa [PDF]

Proceedings of the National Academy of Sciences, 2005
Placozoans, the simplest free-living animals, have never been observed to reproduce sexually. Here, we describe molecular evidence for sexual reproduction within one clade of the Placozoa. In a population sample of 10 individuals, within-individual and overall nucleotide diversity were similar to each other and consistent with levels observed in ...
