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

open access: yes, 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 ...

Phylogenetic Relationships within the Opisthokonta Based on Phylogenomic Analyses of Conserved Single-Copy Protein Domains [PDF]

open access: yes, 2011
Many of the eukaryotic phylogenomic analyses published to date were based on alignments of hundreds to thousands of genes. Frequently, in such analyses, the most realistic evolutionary models currently available are often used to minimize the impact of ...

The early ANTP gene repertoire: insights from the placozoan genome. [PDF]

open access: yesPLoS ONE, 2008
The evolution of ANTP genes in the Metazoa has been the subject of conflicting hypotheses derived from full or partial gene sequences and genomic organization in higher animals.

Comparative genomics of large mitochondria in placozoans.

open access: yesPLoS Genetics, 2007
The first sequenced mitochondrial genome of a placozoan, Trichoplax adhaerens, challenged the conventional wisdom that a compact mitochondrial genome is a common feature among all animals.

Placozoa – no longer a phylum of one [PDF]

open access: yesCurrent Biology, 2004
AbstractMore than a century ago, the simplest of all metazoans was discovered and described as Trichoplax adhaerens[1]. These tiny, flattened animals lack symmetry, mouth, gut, nervous system, and extra-cellular matrix and constitute the apparently monotypic phylum Placozoa.

Действие прямоугольных электрических импульсов низкой частоты на трихоплакса (тип Placozoa)

open access: yesMarine Biological Journal, 2020
The effect of extremely low frequency electric and magnetic fields (ELF-EMF) on plants and animals including humans is quite a contentious issue. Little is known about ELF-EMF effect on hydrobionts, too.

Innate immunity in the simplest animals – placozoans

open access: yesBMC Genomics, 2019
Background Innate immunity provides the core recognition system in animals for preventing infection, but also plays an important role in managing the relationship between an animal host and its symbiont.

Reply to Halanych et al.: Ctenophore misplacement is corroborated by independent datasets [PDF]

open access: yes, 2016
In their letter, Halanych et al. (1) criticize our recent assertion (2) that the phylogenetic placement of ctenophores as the sister group to all other animals (the Ctenophora-sister hypothesis) in three previous studies (3–5) was an artifact caused by ...

Rho Family of Ras-Like GTPases in Early-Branching Animals

open access: yesCells, 2020
Non-bilaterian animals consist of four phyla; Porifera, Cnidaria, Ctenophora, and Placozoa. These early-diverging animals are crucial for understanding the evolution of the entire animal lineage.

Mathematical modeling and comparison of protein size distribution in different plant, animal, fungal and microbial species reveals a negative correlation between protein size and protein number, thus providing insight into the evolution of proteomes [PDF]

open access: yes, 2012
Background The sizes of proteins are relevant to their biochemical structure and for their biological function. The statistical distribution of protein lengths across a diverse set of taxa can provide hints about the evolution of proteomes. Results Using
