Placozoa: at least two

Biologia, 2007
It was shown that compensatory base changes (CBCs) in internal transcribed spacer 2 (ITS2) sequence-structure alignments can be used for distinguishing species. Using the ITS2 Database in combination with 4SALE — a tool for synchronous RNA sequence and secondary structure alignment and editing — in this study we present an in-depth CBC analysis for ...

Annotation of a New Low Voltage Activated Calcium Channel of Trichoplax adhaerens (Phylum Placozoa)

Biofizika
Studying the voltage-gated calcium channels sheds light on the formation of systems responsible for the coupling of sensors and actuators in a living cell. A homologue of 2090 aa lUNKth in the Trichoplax sp.

Placozoa

2023
PREFAZIONE Perché un nuovo testo di Zoologia? La risposta sta innanzitutto nella quantità di nuove informazioni, derivanti dagli studi basati sull’uso di approcci cladistici e molecolari, che hanno rivoluzionato le nostre conoscenze sui rapporti filogenetici tra gli animali, soprattutto invertebrati.

Spherical forms ofTrichoplax adhaerens (Placozoa)

Zoomorphology, 1990
Two types of spherical forms of this normally flattened organism appear sporadically in our cultures. Hollow spheres have an outer wall of flagellated ventral epithelium. The large fiber cells protrude into the central cavity which can include a closed compartment of flagellated dorsal epithelium.

On the genetic uniformity of the genus Trichoplax (Placozoa)

Russian Journal of Genetics, 2004
Fragments of the nuclear and mitochondrial genes for the large-subunit rRNA were compared for Trichoplax sp. and T. adhaerens. High similarity was observed for their sequences, suggesting that different Trichoplax isolates belong to one species.

Alternative modes of asexual reproduction inTrichoplax adhaerens (Placozoa)

Zoomorphology, 1991
Hollow swarmers are budded off at the dorsal surface ofTrichoplax and are covered by dorsal epithelium. Their inner cavity is lined with the flagellated cells of the ventral epithelium. There is no indication that the fiber cells included between the epithelia take any part either in morphologenesis or the separation of the bud from the mother animal ...

Placozoa and the evolution of Metazoa and intrasomatic cell differentiation

The International Journal of Biochemistry & Cell Biology, 2009
The multicellular Metazoa evolved from single-celled organisms (Protozoa) and usually - but not necessarily - consist of more cells than Protozoa. In all cases, and thus by definition, Metazoa possess more than one somatic cell type, i.e. they show-in sharp contrast to protists-intrasomatic differentiation.

Does apicortin, a characteristic protein of apicomplexan parasites and placozoa, occur in Eumetazoa?

Acta Parasitologica, 2018
Apicortin is a characteristic protein of apicomplexan parasites which has recently been identified in their free-living cousins, chromerids as well. The placozoan Trichoplax adhaerens is the only animal possessing this protein and apicortin is one of its
