Morphological consequences for multi-partner chimerism in Botrylloides, a colonial urochordate
Conservation of the developmental role of Brachyury in notochord formation in a urochordate
, the ascidian Halocynthia roretzi.
Conversely, other interactions related to later events in nervous system formation that occur after neural crest induction in vertebrates appear to be conserved between urochordates
In most larval urochordates the notochord provides a stiff skeletal element for the tail, but it must also be flexible to facilitate swimming and other movements.
Evolutionary history of free-swimming and sessile lifestyles in urochordates as deduced from 18S rDNA molecular phylogeny.
Here we test the hypothesis that age of a specific developmental stage in the urochordate
appendicularian Oikopleura dioica Fol, 1872, can be predicted from the number of endostyle cells and temperature, thus serving as such a reference system.
The urochordates were not included in this calculation because of their high correlation between egg diameter and cell cycle duration.
The positive correlation was not significant in the spiralians or urochordates, perhaps because of the small sample sizes.
Developmental expression of Pax 1/9 genes in urochordate
and hemichordate gills: insight into function and evolution of the pharyngeal epithelium.
(ascidians and thaliaceans) overwhelmingly display one mode of sex also found in barentsiid kamptozoans, namely HhH (Berrill, 1975).
Cyclical generation and degeneration of organs in a colonial urochordate
involves crosstalk between old and new: a model for development and regeneration.
Coexisteuce and possible parasitism of somatic and germ cell lines in chimeras of the colonial urochordate
Purification and characterization of a humoral opsonin from the solitary urochordate
