Using a sequential blast pipeline, we phylogenetically classified these genes, as well as those associated with other tissues, in order to define tissue-specific profiles of gene emergence. (biomedcentral.com)
We propose that the evolution of the neural crest is linked not only to the recruitment of ancestral regulatory genes but also to the emergence of signaling peptides that control the increasingly complex lineage diversification of this plastic cell population. (biomedcentral.com)
In the species-rich Phylum Arthropoda, the mitochondrial genome is relatively well conserved both in terms of number and order of genes. (bvsalud.org)
Furthermore, the expression of the majority of these genes during protostome ontogeny suggests a likely role in development. (biomedcentral.com)
Neural1
Our comparative analyses show that, among different tissues, the neural crest exhibits a particularly high rate of gene emergence during vertebrate evolution. (biomedcentral.com)
Simplicity1
Despite the apparent simplicity of poriferans and cnidarians as organisms, these phyla encode a greater diversity of TSP superfamily members than vertebrates. (bvsalud.org)
Evolution2
The emergence of these pluripotent cells is linked to the evolution of more sophisticated sensory and predatory organs (for instance, jaws). (biomedcentral.com)
Notably, the ontogeny of sea lamprey hemoglobins essentially recapitulates their phylogeny, with the embryonic hemoglobins emerging first, followed by the evolution of larval and adult hemoglobins. (biomedcentral.com)
Animal2
Morphological characters alone, however, have obvious limitations in determining phylogeny within the animal kingdom. (what-when-how.com)
With benefit of the growth in genome- and transcriptome-predicted proteomes of a much wider range of animal species, examination of TSPs throughout metazoan phyla has revealed extensive conservation of subgroup B-type TSPs in invertebrates. (bvsalud.org)
