The continuous observation of living animals and the reconstruction of serial sections of fixed specimens have revealed 15 developmental stages and their timetable in palleal buds of the compound ascidian, Symplegma reptans. The bud primordium (stage

In the tunicate, Polyandrocarpa misakiensis, transdifferentiation occurs in the multipotent atrial epithelium during morphallactic bud development. Irradiation (10–80 Gy) or aphidicolin (10 μg/mL) blocked this process severely, although the atrial

Eggs of the hermaphrodite, self-sterile ascidian, Ciona intestinalis, were washed with acid seawater (pH 3.2), and the washing solution was then adjusted to pH 8.2. This solution was found to inhibit only the binding of non-autologous sperm to the vi

In the self sterile ascidian, Ciona intestinalis, the spermatozoa rarely bind to the vitelline coat of autologous eggs and never penetrate it. We report here that concanavalin A (ConA), a lectin recognizing mannose or glucose residues of carbohydrate

The life history of oozooids of a polyclinid ascidian, Polyclinum aurantium was studied by rearing them in small tanks. A newly metamorphosed zooid has four rows of stigmata, and lacks a postabdomen. Three (or four) new stigmatal rows are added to th

The life history of Symplegma reptans was studied by repeated observations on particular living animals and by observations on sectioned materials.The oozooid produces its first bud about 10 days (17° -20° C) after metamorphosis, and produces a ser

The life history of the polyclinid ascidian, Parascidia flemingii was studied in the laboratory from its larval stage to the blastozooid stage. This species is like Circinalium concrescens (Sidnyum turbinatum?) in its external appearance. The present

Spatiotemporal distribution of mitosis and anteroposterior body patterning during morphallactic development of palleal buds in the ascidian, Polyandrocarpa misakiensis, have been studied histologically in the presence or absence of 1.5 mM colchicine.

Colonial growth of the ascidian, Botrylloides simodensis, has been investigated in laboratory conditions. Two strains, S81 and S85, were used. Animals attached on glass slides were held vertically in the culture tank that contained five liters of nat

We have determined how many elements are involved in the regulation of self-fertilization in the solitary ascidian, Ciona intestinalis that is an incompletely self-sterile species. Animals collected in the field were repeatedly induced to spawn in or
