A low diversity of ANTP class homeobox genes in Placozoa

Evolution & Development, 2006
SUMMARYHomeobox genes of the ANTP and PRD classes play important roles in body patterning of metazoans, and a large diversity of these genes have been described in bilaterian animals and cnidarians.Trichoplax adhaerens(Phylum Placozoa) is a small multicellular marine animal with one of the simplest body organizations of all metazoans, showing no ...

Evolutionary origin of the nervous system from Ctenophora prospective

Evolution &Development, Volume 26, Issue 4, July 2024.
This review discusses the evolutionary origin of the nervous system in light of the latest findings in the neuroscience of Ctenophora, one of the most enigmatic and earliest diverging animal lineages. Abstract Nervous system is one of the key adaptations underlying the evolutionary success of the majority of animal groups. Ctenophores (or comb jellies)

Early animal evolution: a morphologist's view [PDF]

Royal Society Open Science, 2019
Two hypotheses for the early radiation of the metazoans are vividly discussed in recent phylogenomic studies, the ‘Porifera-first’ hypothesis, which places the poriferans as the sister group of all other metazoans, and the ‘Ctenophora-first’ hypothesis ...

Action Potentials and Na+ voltage-gated ion channels in Placozoa

, 2020
Placozoa are small disc-shaped animals, representing the simplest known, possibly ancestral, organization of free-living animals. With only six morphological distinct cell types, without any recognized neurons or muscle, placozoans exhibit fast effector ...

Molecular mechanisms of perilipin protein function in lipid droplet metabolism

FEBS Letters, Volume 598, Issue 10, Page 1170-1198, May 2024.
Lipid droplets (LDs) are important for the storage of energy and lipid components. The perilipin family in mammals includes five proteins (PLIN1 to PLIN5), all of which are abundant on the surface of LDs in different tissues and play a role in LD stability and degradation by lipases.

Comparative genomics and the nature of placozoan species. [PDF]

PLoS Biology, 2018
Placozoans are a phylum of nonbilaterian marine animals currently represented by a single described species, Trichoplax adhaerens, Schulze 1883. Placozoans arguably show the simplest animal morphology, which is identical among isolates collected ...

Energy transfer within phycocyanin trimers of Mastigocladus laminosus studied by picosecond time-resolved transient absorption spectroscopy [PDF]

, 1987
The transient absorption recovery induced in phycocyanin trimers by picosecond pulses of variable wavelength (570 — 620 nm) has been recorded and analyzed by applying a least-squares multi-exponential fit procedure.

Deep‐sea meiofaunal communities in the south‐eastern Levantine basin and their shaping factors – Morphological‐taxonomy‐free metabarcoding approach

Ecology and Evolution, Volume 14, Issue 3, March 2024.
The hitherto poorly investigated meiofaunal communities of the south‐eastern part of the Levantine basin were characterized and their relationships with sedimentary and bottom terrain parameters were interpreted. The construction of community composition profiles took an approach that combined metabarcoding with sample reads normalization by abundance.

Evo-devo of non-bilaterian animals

Genetics and Molecular Biology, 2015
The non-bilaterian animals comprise organisms in the phyla Porifera, Cnidaria, Ctenophora and Placozoa. These early-diverging phyla are pivotal to understanding the evolution of bilaterian animals.
