Experiments on ciona intestinalis

Nature, 1923
IN the issue of NATURE for November 3, p. 653, there appears a letter from my old friend and former colleague, Mr. H. M. Fox, in which he records an attempt which he made this summer to repeat Dr. Kammerer's experiments on Ciona. These experiments consisted in inducing an abnormal growth of the siphons of Ciona by repeated amputation. Mr. Fox amputated

Vasopressin Promoter Transgenic and Vasopressin Gene-Edited Ascidian, Ciona intestinalis Type A (Ciona robusta): Innervation, Gene Expression Profiles, and Phenotypes

open access: yesFrontiers in Endocrinology, 2021
Oxytocin (OT) and vasopressin (VP) superfamily neuropeptides are distributed in not only vertebrates but also diverse invertebrates. However, no VPergic innervation of invertebrates has ever been documented.

Experiments on Ciona and Alytes

Nature, 1923
IN NATURE of November 3, page 653, Mr. H. Munro Fox announces that he did not succeed in repeating my results in his Ciona experiments in Roscoff: amputated siphons regained only their normal length. Mr. Fox supposes that the extra growth in length of the siphons in my experiments was produced by extravagant feeding, and not by the regenerative ...

The Gut of Geographically Disparate Ciona intestinalis Harbors a Core Microbiota

open access: yesPLoS ONE, 2014
It is now widely understood that all animals engage in complex interactions with bacteria (or microbes) throughout their various life stages. This ancient exchange can involve cooperation and has resulted in a wide range of evolved host-microbial ...

Ciona as a Simple Chordate Model for Heart Development and Regeneration

open access: yesJournal of Cardiovascular Development and Disease, 2016
Cardiac cell specification and the genetic determinants that govern this process are highly conserved among Chordates. Recent studies have established the importance of evolutionarily-conserved mechanisms in the study of congenital heart defects and ...

Comparative morpho-physiological analysis between Ciona robusta and Ciona savignyi

Journal of Experimental Marine Biology and Ecology, 2016
Abstract The seasquirt Ciona robusta and its co-generic Ciona savignyi , are two long-divergent species, sharing the same habitat and competing for the same spaces and resources. Their very similar morphology has been responsible for the misidentification of the two organisms, and, consequently, for the underestimation of their geographic ...

Siphon regeneration in Ciona

Nature, 1975
IN 1923 Paul Kammerer summarised research which he claimed demonstrated the inheritance of acquired characteristics. Since the success of Mendelian genetics had already made Kammerer's work suspect a report of his lecture1 was followed by a long and acrimonious debate. The Kammerer case thereby became a cause celebre in the biology of that decade.

Computational Identification of Ciona intestinalis MicroRNAs

Zoological Science, 2010
MicroRNAs (miRNAs) are conserved non-coding small RNAs with potent post-transcriptional gene regulatory functions. Recent computational approaches and sequencing of small RNAs had indicated the existence of about 80 Ciona intestinalis miRNAs, although it was not clear whether other miRNA genes were present in the genome.
