Natural Products from Antarctic Colonial Ascidians of the Genera <em>Aplidium</em> and <em>Synoicum</em>: Variability and Defensive Role [PDF]
Marine Drugs, 2012 Ascidians have developed multiple defensive strategies mostly related to physical, nutritional or chemical properties of the tunic. One of such is chemical defense based on secondary metabolites.

Speed vs completeness: a comparative study of solitary and colonial tunicate embryogenesis [PDF]
Frontiers in Cell and Developmental BiologySolitary ascidians, such as Ciona robusta, have been used for over a century as model systems for embryological studies. These species are oviparous, producing many relatively small and transparent eggs, which are released and fertilized outside the ...

Molecular phylogeny implies exclusive, repetitive, convergent establishment of cyanobacterial symbiosis in didemnid ascidians (Tunicata: Ascidiacea: Didemnidae) [PDF]
Zoological LettersDespite the great diversity of the phylum Chordata, lifelong obligate symbiosis with cyanobacteria is only known in certain species belonging to four genera of didemnid ascidians: Didemnum, Diplosoma, Lissoclinum, and Trididemnum.

New Data on the Rhamnose-Binding Lectin from the Colonial Ascidian Botryllus schlosseri: Subcellular Distribution, Secretion Mode and Effects on the Cyclical Generation Change [PDF]
Marine Drugs, 2023 Botryllus schlosseri in a cosmopolitan ascidian, considered a reliable model organism for studies on the evolution of the immune system. B. schlosseri rhamnose-binding lectin (BsRBL) is synthesised by circulating phagocytes and behaves as an opsonin by ...

Colonial Allorecognition, Hemolytic Rejection, and Viviparity in Botryllid Ascidians. [PDF]
Zoological Science, 2003 Allorecognition is a fundamental system that animals use to maintain individuality. Although embryos are usually semiallogeneic with their mother, viviparous animals are required to allow these embryos to develop inside the maternal body, but must also eliminate an "invasion" by nonself.

Microbial Communities Vary by Body Region but Remain Consistent Across Color Morphs in the Solitary Ascidian Rhopalaea abdominalis [PDF]
International Journal of MicrobiologyAscidians are filter-feeding marine invertebrates that display inter- and intraspecific color variation and host diverse microbiomes. Although color variation has been used as an indicator of speciation and correlated with distinct microbiome structure ...

Comparative Morphology of the Stolonic Vessel in a Didemnid Ascidian and Some Related Tissues in Colonial Ascidians [PDF]
Zoological Science, 2004 The stolonic vessel is a tubular projection of the epidermis from the anterior part of the abdomen in the didemnid ascidians, and the vessel has been supposed to be closely related to the stolons, vascular appendages, and the posterior ends of the abdomen in other aplousobranch ascidians.

Effects of color variation and physiological state on ascidian microbiomes [PDF]
MicrobiologyOpenAscidians, known for their color variation, host species‐specific microbial symbiont communities. Some ascidians can also transition into a nonfiltering (resting) physiological state.
