Evolution of Allorecognition in the Tunicata

open access: yesBiology, 2020
Allorecognition, the ability to distinguish self or kin from unrelated conspecifics, plays several important biological roles in invertebrate animals. Two of these roles include negotiating limited benthic space for colonial invertebrates, and inbreeding

Serotonin Receptors and Their Involvement in Melanization of Sensory Cells in Ciona intestinalis

open access: yesCells, 2023
Serotonin (5-hydroxytryptamine (5-HT)) is a biogenic monoamine with pleiotropic functions. It exerts its roles by binding to specific 5-HT receptors (5HTRs) classified into different families and subtypes.

Inflammatory hemocytes in Ciona intestinalis innate immune response [PDF]

open access: yesInvertebrate Survival Journal, 2009
In the present paper an attempt is carried out to revise Ciona intestinalis inflammatory hemocytes according to their morphology as formerly observed by light and electron microscopy, and taking in account recent reports on innate immunity gene ...

Report on the 2013 Rapid Assessment Survey of Marine Species at New England Bays and Harbors [PDF]

open access: yes, 2014
Introduced species (i.e., non-native species that have become established in a new location) have increasingly been recognized as a concern as they have become more prevalent in marine and terrestrial environments (Mooney and Cleland 2001; Simberloff et ...

De novo draft assembly of the Botrylloides leachii genome provides further insight into tunicate evolution [PDF]

open access: yes, 2018
Tunicates are marine invertebrates that compose the closest phylogenetic group to the vertebrates. These chordates present a particularly diverse range of regenerative abilities and life-history strategies.

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

open access: yesInvertebrate 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.

Microscopic and Genetic Characterization of Bacterial Symbionts With Bioluminescent Potential in Pyrosoma atlanticum

open access: yesFrontiers in Marine Science, 2021
The pelagic tunicate pyrosome, Pyrosoma atlanticum, is known for its brilliant bioluminescence, but the mechanism causing this bioluminescence has not been fully characterized. This study identifies the bacterial bioluminescent symbionts of P. atlanticum

Rocky intertidal zonation pattern in Antofagasta, chile: invasive species and shellfish gathering.

open access: yesPLoS ONE, 2014
BackgroundBiological invasions affecting rocky intertidal zonation patterns, yield information on species interactions. In the Bay of Antofagasta, northern Chile, the non-indigenous tunicate Pyura praeputialis, originally from Australia, has invaded (in ...
