Diploid genome reconstruction of Ciona intestinalis and comparative analysis with Ciona savignyi [PDF]

Genome Research, 2007
One of the main goals in genome sequencing projects is to determine a haploid consensus sequence even when clone libraries are constructed from homologous chromosomes. However, it has been noticed that haplotypes can be inferred from genome assemblies by investigating phase conservation in sequenced reads.

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

ParaHox Genes Revisited: From Gut Patterning to Integrated Axial and Neural Organization in Rotifera

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In rotifers, ParaHox genes show a dispersed genomic organization, with Xlox absent across gnathiferans. Exclusive neuronal expression of Gsx and Cdx reveals that ancestral ParaHox genes coordinated neural and epithelial development beyond gut patterning, suggesting an integrated role in early bilaterian body plan organization.

The Embryonic Development of the Cotylean Polyclad Phrikoceros jannetae

Acta Zoologica, EarlyView.
ABSTRACT Polyclads exhibit distinct developmental modes ranging from direct to indirect development, with several transitional stages also recognised. The existence of an indirect developmental mode in polyclads with a planktonic life history stage in the form of a free‐swimming larva is unique among all free‐living flatworms and makes polyclads a ...

Major ascidian species with negative impacts on bivalve aquaculture: Current knowledge and future research aims

Open Geosciences
Biofouling constitutes one of the main obstacles in the sector of shellfish farming. Under this perspective, it is of highly importance to critically combine the updated information regarding the invasive potential of ascidian species, together with the ...

Identification and population genetic comparison of three ascidian species based on mtDNA sequences

Ecology and Evolution, 2020
Ascidians are sessile marine chordate invertebrates found along seashores worldwide and are typically regarded as invasive organisms. Knowledge concerning their global genetic structure and subsequent invasive potential is limited.

Zebrafish as a model for Catel–Manzke syndrome—identification and characterization of the zebrafish TGDS ortholog

The FEBS Journal, EarlyView.
Zebrafish Tgds, when expressed as a recombinant protein, catalyzes the dehydration of UDP‐D‐glucose, the initial step in the formation of 6‐deoxyhexoses. Corresponding Tgds mutations found in Catel–Manzke syndrome patients lead to reduced enzymatic activity and stability.

The nervous system of the adult ascidian Ciona intestinalis Type A (Ciona robusta): Insights from transgenic animal models. [PDF]

PLoS ONE, 2017
The nervous system of ascidians is an excellent model system to provide insights into the evolutionary process of the chordate nervous system due to their phylogenetic positions as the sister group of vertebrates.

The Greenland–Scotland Ridge in a Changing Ocean: Time to Act?

Marine Ecology, EarlyView.
ABSTRACT The Greenland–Scotland Ridge is a submarine mountain that rises up to 500 m below the sea surface and extends from the east coast of Greenland to the continental shelf of Iceland and across the Faroe Islands to Scotland. The ridge not only separates deeper ocean basins on either side, that is, the North Atlantic and Arctic oceans, but also ...

Gene expression and cellular changes in injured myocardium of Ciona intestinalis

Frontiers in Cell and Developmental Biology
Ciona intestinalis is an invertebrate animal model system that is well characterized and has many advantages for the study of cardiovascular biology. The regulatory mechanisms of cardiac myocyte proliferation in Ciona are intriguing since regeneration of
