Abstract:
Tunicates are the sister group of vertebrates and thus occupy a key position for investigations into vertebrate innovations as well as into the consequences of the vertebrate-specific genome duplications. Nevertheless, tunicate genomes have not been studied extensively in the past, and comparative studies of tunicate genomes have remained scarce. The carpet sea squirt Didemnum vexillum, commonly known as “sea vomit”, is a colonial tunicate considered an invasive species with substantial ecological and economical risk. We report the assembly of the D. vexillum genome using a hybrid approach tha

Abstract:
The deuterostomes are a monophyletic group of multicellular animals that include the Chordata, a phylum that exhibits a unique body plan within the metazoans. Deuterostomes classically contained three phyla, Echinodermata, Hemichordata, and Chordata. Protochordata describes two invertebrate chordate subphyla, the Tunicata (Urochordata) and the Cephalochordata. Tunicate species are key to understanding chordate origins, as they have tadpole larvae with a chordate body plan. However, molecular phylogenies show only weak support for the Tunicata as the sister-group to the rest of the chordates, s

Abstract:
Five new bicyclic carboxylic acids were obtained by antibacterial activity-guided isolation from a Korean colonial tunicate Didemnum sp. Their structures were elucidated by the interpretation of NMR, MS and CD spectroscopic data. They all belong to the class of aplidic acids. Three of them were amide derivatives (1–3), and the other two were dicarboxylic derivatives (4 and 5). The absolute configurations were determined by a bisignate pattern of CD spectroscopy, which revealed that the absolute configurations of amides were opposite to those of dicarboxylates at every stereogenic centers.

In this work, we studied the nervous and sensory system of the colonial ascidian Botryllus schlosseri during the development of embryos, buds, and in adult individuals belonging to young and old colonies. B. schlosseri is a colonial ascidian in which individuals (blastozooids) are organized in star-shaped systems. In a colony, sexual and asexual reproductions are coordinated and cyclical. Moreover, three generations of zooids coexist: adults (filter-feeding individuals), their buds (primary buds), and the budlets (secondary buds) produced by buds.

AbstractAscidians are sessile tunicates, that is, marine animals belonging to the phylum Chordata and considered the sister group of vertebrates. They are widespread in all the seas, constituting abundant communities in various ecosystems. Among chordates, only tunicates are able to reproduce asexually, forming colonies. The high regenerative potentialities enabling tunicates to regenerate damaged body parts, or the whole body, represent a peculiarity of this taxon.

Colonial tunicates are the only know chordates that have been shown to undergo whole-body regeneration (WBR). Botrylloides in particular can regenerate one fully functional adult from a minute fragment of their vascular system in as little as 10 days. This regenerative process relies on the proliferation of circulating stem cells, likely supported by the activity of some of the 11 identified types of hemocytes.

Abstract The three thaliacean groups, pyrosomas, salps and doliolids, differ from each other not only in their anatomy, but also in their locomotion, buoyancy, sensory systems and embryonic development. They share, however, metagenetic life-cycles involving alternation of generations (although one generation is only transient in pyrosomas) and essentially similar stolonic budding. Traditionally grouped together, a grouping retained here for convenience, it now seems probable that the Thaliacea are polyphyletic, and thus that their grouping together is artificial (Chapter 16).Pyrosomas are colo
