Mobile DNA, 2019 Background The transfer of genetic material from non-parent organisms is called horizontal gene transfer (HGT). One of the most conclusive cases of HGT in metazoans was previously described for the cellulose synthase gene in ascidians.

DNA Content and Fragmentation of the Egg Nucleus of Trichoplax adhaerens
Zeitschrift für Naturforschung C, 1981 Abstract Under culture conditions the egg nucleus of Trichoplax adhaerens reaches an unusually high and variable DNA content. Before the "fertilization membrane" is formed, the nucleus undergoes fragmentation. It is assumed that culture conditions differ from natural conditions by preventing the switch-over from the S-phase to the G 2 ...

Distinct expression patterns of the two T-box homologues Brachyury and Tbx2/3 in the placozoan Trichoplax adhaerens [PDF]
, 2018 Trichoplax adhaerens is the only species known from the phylum Placozoa with one of the simplest metazoan body plans. In the small disc-like organism an upper and a lower epithelium can be distinguished with a less compact third cell layer in between ...

From tumors to species: a SCANDAL hypothesis
Biology Direct, 2019 Some tumor cells can evolve into transmissible parasites. Notable examples include the Tasmanian devil facial tumor disease, the canine transmissible venereal tumor and transmissible cancers of mollusks.

Electron tomography dataset of a serial sectioned Trichoplax haplotype H2 fiber cell
, 2019 A Hawaiian Trichoplax haplotype H2 was high pressure frozen, embedded in epoxy resin, serial sectioned (300nm thickness), stained with uranyl acetate and lead citrate and gold particles applied to each side of the section.

Fast calcium-dependent reorientation of motile cilia basal bodies in the simple metazoan, Trichoplax
Ciliary-based animal locomotion relies on the spatially coordinated beating of motile cilia to displace the body in liquid environments or across solid surfaces.
