Characterization of a novel species-specific 51-amino acid peptide, PEP51, as a caspase-3/7 activator in ovarian follicles of the ascidian, Ciona intestinalis Type A

open access: yesFrontiers in Endocrinology, 2023
Invertebrates lack hypothalamic-pituitary-gonadal axis, and have acquired species-specific regulatory systems for ovarian follicle development. Ascidians are marine invertebrates that are the phylogenetically closest living relatives to vertebrates, and ...

Characterization of calcium transients during early embryogenesis in ascidians Ciona robusta (Ciona intestinalis type A) and Ciona savignyi

open access: yesDevelopmental Biology, 2017
The calcium ion (Ca2+) is an important second messenger, and a rapid increase in Ca2+ level (Ca2+ transient) is involved in various aspects of embryogenesis. Although Ca2+ transients play an important role in early developmental stages, little is known about their dynamics throughout embryogenesis.

Amylibacter cionae sp. nov., isolated from the sea squirt Ciona savignyi

open access: yesInternational Journal of Systematic and Evolutionary Microbiology, 2017
A Gram-stain-negative, non-motile, aerobic and rod-shaped bacterial strain, designated H-12T, was isolated from a sea squirt (Ciona savignyi) collected from Tsingtao Port, Jiaozhou Bay, China, and its taxonomic position was investigated. Strain H-12T grew optimally at 25-30 °C, at pH 7.0-8.0 and in the presence of 3.0-4.0 % (w/v) NaCl.

CRISPR Knockouts in Ciona Embryos [PDF]

open access: yes, 2018
Clustered regularly interspaced short palindromic repeats (CRISPR)/Cas9 has emerged as a revolutionary tool for fast and efficient targeted gene knockouts and genome editing in almost any organism. The laboratory model tunicate Ciona is no exception.

Developmental system drift in motor ganglion patterning between distantly related tunicates

open access: yesEvoDevo, 2018
Background The larval nervous system of the solitary tunicate Ciona is a simple model for the study of chordate neurodevelopment. The development and connectivity of the Ciona motor ganglion have been studied in fine detail, but how this important ...

The repertoire of G protein-coupled receptors in the sea squirt Ciona intestinalis

open access: yesBMC Evolutionary Biology, 2008
Background G protein-coupled receptors (GPCRs) constitute a large family of integral transmembrane receptor proteins that play a central role in signal transduction in eukaryotes. The genome of the protochordate Ciona intestinalis has a compact size with

The Cis-Regulatory Code for Kelch-like 21/30 Specific Expression in Ciona robusta Sensory Organs

open access: yesFrontiers in Cell and Developmental Biology, 2020
The tunicate Ciona robusta is an emerging model system to study the evolution of the nervous system. Due to their small embryos and compact genomes, tunicates, like Ciona robusta, have great potential to comprehend genetic circuitry underlying cell ...

Xbp1 and Brachyury establish an evolutionarily conserved subcircuit of the notochord gene regulatory network

open access: yeseLife, 2022
Gene regulatory networks coordinate the formation of organs and structures that compose the evolving body plans of different organisms. We are using a simple chordate model, the Ciona embryo, to investigate the essential gene regulatory network that ...

Unprecedented Diversity of ssDNA Phages from the Family Microviridae Detected within the Gut of a Protochordate Model Organism (Ciona robusta)

open access: yesViruses, 2018
Phages (viruses that infect bacteria) play important roles in the gut ecosystem through infection of bacterial hosts, yet the gut virome remains poorly characterized.
