DrosophilaP transposons of the urochordata Ciona intestinalis

Molecular Genetics and Genomics, 2009
P transposons belong to the eukaryotic DNA transposons, which are transposed by a cut and paste mechanism using a P-element-coded transposase. They have been detected in Drosophila, and reside as single copies and stable homologous sequences in many vertebrate species.

Hemichordata And Urochordata

1990
Abstract Hemichordates comprise worm-like Enteropneusta ( = Balanoglossida) and tentaculate Pterobranchia. Enter-opneusts have gill slits very like those of Amphioxus (Ch. 17) so are linked with chordates, particularly because they also have a dorsal, sometimes tubular, nerve cord in the collar (a short region just behind the mouth ...

Chemotactic Responses of Tunicate (Urochordata, Ascidiacea) Hemocytesin Vitro

Journal of Invertebrate Pathology, 1998
A number of molecules were found to alter the motility of tunicate hemocytes. Bacterial lipopolysaccharide (LPS) significantly enhanced cell mobility relative to non-stimulated controls. Responses to LPS were not directional and so represented chemokinesis.

Pigmentation and tunic cells in Cystodytes dellechiajei (Urochordata, Ascidiacea)

Zoomorphology, 2001
The tunic of Cystodytes dellechiajei (Poly- citoridae), a colony-forming species of the Ascidiacea that contains biologically active alkaloids, was investigated using light microscopy, laser-scanning microscopy and nuclear magnetic resonance techniques. The colonies contain numerous individual zooids, which are embedded in a common tunic. Each zooid is

A Protozoan Parasite of Molgula manhattensis (De Kay) (Urochordata)

Nature, 1966
DURING the course of an investigation into oogenesis in the ascidian Molgula manhattensis a protozoan was discovered parasitizing a few of the nearly mature and fully mature eggs of one gonad. The ascidian which contained the infected gonad was one of several of the same species taken from Plymouth Sound in June 1963.
