Two intracellular and cell type-specific bacterial symbionts in the placozoan Trichoplax H2

, 2019
Placozoa is an enigmatic phylum of simple, microscopic, marine metazoans(1,2). Although intracellular bacteria have been found in all members of this phylum, almost nothing is known about their identity, location and interactions with their host(3-6). We

The phylogenetic position of ctenophores and the origin(s) of nervous systems [PDF]

, 2015
Ctenophores have traditionally been treated as eumetazoans, but some recent whole genome studies have revived the idea that they are, rather, the sister group to all other metazoans.

Expansion microscopy in Placozoa: improving resolution and preservation of fragile samples during marine expedition

Frontiers in Marine Science
Placozoa are small disc-shaped animals representing one of the early branching metazoan lineages with only a dozen cell types, fast effector reactions, and complex behaviors.

A pre-metazoan origin of the CRK gene family and co-opted signaling network. [PDF]

, 2016
CRK and CRKL adapter proteins play essential roles in development and cancer through their SRC homology 2 and 3 (SH2 and SH3) domains. To gain insight into the origin of their shared functions, we have investigated their evolutionary history.

Non-coding RNA annotation of the genome of Trichoplax adhaerens [PDF]

Nucleic Acids Research, 2009
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 genome has been published to-date.

MicroRNAs and essential components of the microRNA processing machinery are not encoded in the genome of the ctenophore Mnemiopsis leidyi

BMC Genomics, 2012
Background MicroRNAs play a vital role in the regulation of gene expression and have been identified in every animal with a sequenced genome examined thus far, except for the placozoan Trichoplax. The genomic repertoires of metazoan microRNAs have become

The evolutionary history of histone H3 suggests a deep eukaryotic root of chromatin modifying mechanisms [PDF]

, 2010
Background The phenotype of an organism is an outcome of both its genotype, encoding the primary sequence of proteins, and the developmental orchestration of gene expression.

The ventral epithelium of Trichoplax adhaerens deploys in distinct patterns cells that secrete digestive enzymes, mucus or diverse neuropeptides

Biology Open, 2019
The disk-shaped millimeter-sized marine animal, Trichoplax adhaerens, is notable because of its small number of cell types and primitive mode of feeding.

Support for a clade of Placozoa and Cnidaria in genes with minimal compositional bias

eLife, 2018
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 ...

Expression and phylogenetic analysis of the zic gene family in the evolution and development of metazoans [PDF]

, 2010
Background zic genes are members of the gli/glis/nkl/zic super-family of C2H2 zinc finger (ZF) transcription factors. Homologs of the zic family have been implicated in patterning neural and mesodermal tissues in bilaterians ...
