Ascidians, and Other Invertebrate Deuterostomes
: Experimental Approaches, A.
is a broad category that includes animals ranging from the gigantic blue whale to the tiny arrow worm.
The chordates (that include vertebrates), hemichordates (that include the living "acorn worms"), and echinoderms (that include the living starfish and echinoids) are all deuterostomes
and have the same pattern of early embryo development.
Could it be that the ancestor of the deuterostomes
was a bottom-feeding dweller in the dark?
Acoelomorph flatworms are deuterostomes
related to Xenoturbella.
This study provides a framework for future research aimed at uncovering the cell types and genetic mechanisms underlying the regeneration process in this basal deuterostome
. Adult P.
Gastrulation, in several deuterostome
taxa, has been studied in sufficient detail to provide a good example of the roles of ECM components in a fundamental developmental system.
The molecular circadian clocks in mammals and fruit flies represent two major lineages of animals: deuterostome
chordates and protostome ecdysozoans, respectively.
superphylum comprises the chordates, which include all vertebrates, hemichordates (acorn worms), and echinoderms (Satoh et al., 2014); echinoderms themselves are comprised of sea urchins, sea stars, brittle stars, sea cucumbers, sand dollars, and crinoids.
Evolution of galanin receptor genes: insights from the deuterostome
Amplification with BsGSF and BsGSR resulted in an amplicon of 304-bp sharing similarity with other deuterostome
glutathione synthases (GSs) (GenBank accession no.
