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.

Brief History of Placozoa

Placozoans are morphologically the simplest free-living animals. They represent a unique window of opportunities to understand both the origin of the animal organization and the rules of life for the system and synthetic biology of the future. However, despite more than 100 years of their investigations, we know little about their organization, natural

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.

Microfilaments and microtubules in isolated fiber cells of Trichoplax adhaerens (Placozoa)

Zoomorphology, 1989
Fiber cells isolated by mechanical disruption of the tissue in Ca2+-free sea water attach firmly to the substrate by discrete adhesion plaques. They are capable of forming a lamellipodium and long, slender extensions while the cell bodies remain stationary. The extensions are slowly elongated but can suddenly be withdrawn by contraction.

Ultrastructural analyses support different morphological lineages in the phylum placozoa Grell, 1971

Journal of Morphology, 2011
AbstractThe morphology and ultrastructure of 10 clonal placozoan lineages were studied. We scored several morphological characters at a cellular and intracellular level and identified a number of morphological differences among clones. Some differences appear clone specific and allow recognizing five distinct lineages based on morphological criteria ...

The evolution of the placozoa: A new morphological model

Senckenbergiana lethaea, 2002
The evolutionary history of the placozoanTrichoplax adhaerens is reconstructed from a hypothetical ‘gallertoid’ ancestor. According to this approach the Placozoa derived from an early benthic gallertoid stage, the ‘placuloid’. The sequence of morphological transformations leading to the placozoan bauplan can be deduced from biomechanical and functional
