... cord to express undulation patterns accommodated to various inputs into the networks. While these systems have been widely studied in vertebrate swimmers, their evolutionary origin along the chordate phylogeny remains unclear. Ascidians, representing a sister group of vertebrates, give rise to tadpole...

... inhibition. Together, these results show that HDAC function, specifically HDAC I/IIa class enzymes, are vital for B. leachii to undergo WBR successfully. Examination of the B. leachii genome alongside additional ascidian genomes revealed that each ascidian genome had two Class I, two Class II...

...Di Jiang; Jason W. Tresser; Takeo Horie; Motoyuki Tsuda; William C. Smith SUMMARY Free-living animals and their larvae utilize light and gravity as cues to navigate in open space. Detection and response to these environmental stimuli are important for the dispersal and settlement of ascidian larvae...

...Claudette Rabinowitz; Baruch Rinkevich SUMMARY In the colonial growth of botryllid ascidians, blastogenesis (bud formation) is a cyclical and synchronized developmental process characterized by a weekly rhythm of budding and apoptotic events. Very little is known about this cycle regulation and its...

...Motoyuki Tsuda; Daisuke Sakurai; Muneki Goda SUMMARY The anterior sensory vesicle of ascidian larvae contains a single large vesicle in which lie two distinct types of pigment cells, anterior and posterior. The ultrastructure of these pigment cells suggests that the anterior pigment cell...

... that swim at Reynolds numbers ( Re ) between 10 0 and 10 2 . We experimentally tested quasi-steady and unsteady blade-element models of the hydrodynamics of undulatory swimming in the larvae of the ascidian Botrylloides sp. by comparing the forces predicted by these models with measured forces generated...

... helically. The present study found no significant asymmetries in the body shape of ascidian larvae ( Distaplia occidentalis ) that could operate to rotate the body during swimming. By recording the three-dimensional movement of free-swimming larvae, it was found that the tail possessed two bends, each...
