Allogeneic Distinction in Botryllus Primigenus and in Other Colonial Ascidians

Advances in Experimental Medicine and Biology, 1975
Certain species of colonial ascidians have colony specificity or the ability to distinguish self colonies from not-self colonies within the same species. In Botryllus primigenus, when a colony recognizes another as belonging to the self strain, both colonies fuse with each other to form one colony (designated as “fusion”).

Some colonial ascidians from Indian waters [PDF]

Deep Sea Research Part B. Oceanographic Literature Review, 1985
38-41Three colonial ascidians are reported of which two are new and one is the 1st record from Indian waters. Ecteinascidia krishnani of the family Perophoridae and Polyandrocarpa chendurensis of the family Pyuridae are new species and Botrylloides ...

Asexual Propagation and Regeneration in Colonial Ascidians

The Biological Bulletin, 2011
Regeneration is widely distributed among the metazoans. However, clear differences exist as to the degree of regenerative capacity: some phyla can only replace missing body parts, whereas others can generate entirely new individuals. Ascidians are animals that possess a remarkable regenerative plasticity and exhibit a great diversity of mechanisms for ...

Characterization of HCN and cardiac function in a colonial ascidian

Journal of Experimental Zoology Part A: Ecological Genetics and Physiology, 2011
AbstractHyperpolarization‐activated, cyclic nucleotide‐gated (HCN) channels generate the rhythmic beating of mammalian hearts. We identified an HCN homolog in the colonial ascidian Botryllus schlosseri, a nonvertebrate chordate which possesses a tubular heart that beats bidirectionally.

Continuous development precludes radioprotection in a colonial ascidian

Developmental & Comparative Immunology, 2004
Colonial organisms provide a unique experimental system for stem cell biology. The colonial Urochordate Botryllus schlosseri reproduces sexually as well as by continuous asexual budding. Adjacent colonies with a shared histocompatibility allele undergo vascular fusion and establish a common blood circulation, performing natural transplantation.

Allorecognition Between Compound Ascidian Colonies

Zoological Science, 2013
The compound ascidian Botryllus schlosseri reproduces asexually, and forms colonies to adhere to matrices such as rocks. This species has developed a mechanism to distinguish between self stem cells and invasive parasitizing nonself cells from other individuals of the same species, probably as a defense against parasitism. It is highly likely that such

Light induced larval release of a colonial ascidian

Journal of Experimental Marine Biology and Ecology, 2000
Larval release and photobehavior were studied in the colonial ascidian Polyandrocarpa zorritensis. The test hypothesis was that if larval release is induced by light, then larvae should be attracted to settlement areas where light is sufficient for larval release. Light induced larval release but the time course varied with light intensity.

Chimeras and histocompatibility in the colonial ascidian Botryllus schlosseri

Developmental & Comparative Immunology, 1988
Chimeras of B. schlosseri were prepared by pairwise combination of colonies sharing one allele at the fusibility gene locus (AD = AC chimeras). A frequent resorption of one of the partners was observed and the resorption time was shown to be significantly correlated with the relative size, the resorbing partner being usually the larger.
