Gonad development and hermaphroditism in the ascidian Botryllus schlosseri.
The colonial ascidian Botryllus schlosseri is an ideal model organism for studying gonad development and hermaphroditism. B. schlosseri has been reared in laboratories for over half a century, and its unique biology allows investigators to probe the processes of germ cell migration and gonad formation, resorption, and regeneration. Following metamorphosis, colonies of B. schlosseri show a synch...
متن کاملAscidian Tunicate, Botryllus schlosseri (Pallas, 1766) infestation on Seahorse
An unusual infection by tunicate ascidians on the trunk part of a seahorse caught by gill ne ing in the Eastern Black Sea Region of Turkey was observed. The colour, zooid diameter and width of the zooids colony of tunicate was determined. The present study is the first report of this condition on seahorses. * Corresponding author’s e-mail: [email protected] Tunicates are marine invertebrate ani...
متن کاملInsights on cytotoxic cells of the colonial ascidian Botryllus schlosseri
Morula cells (MCs) represent the most abundant circulating hemocyte of the compound ascidian Botryllus schlosseri. They are cytotoxic cells involved in the rejection reaction between contacting, genetically incompatible colonies. Upon the recognition of foreign substances, they degranulate and release their content, which contribute to the cell death along the contact borders. A major role in M...
متن کاملOrigin and Dispersal History of Two Colonial Ascidian Clades in the Botryllus schlosseri Species Complex
Human-induced global warming and species introductions are rapidly altering the composition and functioning of Earth's marine ecosystems. Ascidians (Phylum Chordata, Subphylum Tunicata, Class Ascidiacea) are likely to play an increasingly greater role in marine communities. The colonial ascidian B. schlosseri is a cryptic species complex comprising five genetically divergent clades (A-E). Clade...
متن کاملPopulation genetics of the invasive ascidian Botryllus schlosseri from South American coasts
The cosmopolitan colonial ascidian Botryllus schlosseri, most likely a Mediterranean Sea and European Atlantic species, is one of the known human-mediated invaders of coastal marine communities. Whereas numerous populations spreading along the Northern Hemisphere coasts have been intensively studied for various population genetics parameters, the data available on the Southern Hemisphere popula...
