Natural variation of model mutant phenotypes in Ciona intestinalis [PDF]

, 2008
The study of ascidians (Chordata, Tunicata) has made a considerable contribution to our understanding of the origin and evolution of basal chordates. To provide further information to support forward genetics in Ciona intestinalis, we used a combination ...

ULTRASTRUCTURAL FEATURES OF THE CYTOPLASM OF RESPECTIVE KINDS OF CELL LINEAGES OF CLEAVAGE-ARRESTED ASCIDIAN EMBRYO [PDF]

, 1986
We observed the ultrastructual features of the cytoplasm in the cell lineages of the cleavage-arrested embryos of the ascidian, Halocynthia roretzi, and compared them with those of the cytoplasm in the corresponding cell lineages of the normal embryos or

Transcriptional Analysis of the Endostyle Reveals Pharyngeal Organ Functions in Ascidian

Biology, 2023
The endostyle is a pharyngeal organ with an opening groove and cilia in invertebrate chordates (amphioxus and ascidian) and cyclostomate (lamprey), serving as a filter-feeding tract and thyroid-secreting location.

A novel third complement component C3 gene of Ciona intestinalis expressed in the endoderm at the early developmental stages [PDF]

Invertebrate Survival Journal, 2013
The third complement component (C3) in ascidian was reported to function as an opsonin to enhance phagocytosis and as a chemotactic factor for phagocytes, indicating that ascidian C3 works in mesodermal cavity as a humoral factor like vertebrate C3s.

Fertilization of Ascidians: Gamete Interaction, Self/Nonself Recognition and Sperm Penetration of Egg Coat

Frontiers in Cell and Developmental Biology, 2022
Fertilization is one of the most important events in living organisms to generate a new life with a mixed genetic background. To achieve successful fertilization, sperm and eggs must undergo complex processes in a sequential order.

Commensal Leucothoidae (Crustacea, Amphipoda) of the Ryukyu Archipelago, Japan. Part I: ascidian-dwellers

ZooKeys, 2012
Commensal leucothoid amphipods have been collected from the branchial chambers of their ascidian hosts throughout the Ryukyu Archipelago, Japan. Seven new species are described in two genera with valuable location data and host records. An identification

Ascidians Collected in Tanzania

Journal of East African Natural History, 1997
Ascidians were collected in Tanzania in January 1996 by SCUBA diving. Among 31 species reported here, nine are new. Several species were also recently collected in Mozambique. Full descriptions are given with figures and colour plates. The present collection of Tanzanian ascidians significantly increases the number of species known in the tropical ...

Asymmetric Fitness of Second-Generation Interspecific Hybrids Between Ciona robusta and Ciona intestinalis

G3: Genes, Genomes, Genetics, 2020
Reproductive isolation is central to speciation, but interspecific crosses between two closely related species can produce viable and fertile hybrids.

Short-Term Exposure to Nanoplastics Does Not Affect Bisphenol A Embryotoxicity to Marine Ascidian Ciona robusta

Biomolecules, 2022
Plastic pollution is recognized as a global environmental threat and concern is increasing regarding the potential interactions of the smallest fragments, nanoplastics (1 µm), with either physical and chemical entities encountered in the natural ...
