Physiological Changes During Torpor Favor Association With Endozoicomonas Endosymbionts in the Urochordate Botrylloides leachii [PDF]

Frontiers in Microbiology, 2023
Environmental perturbations evoke down-regulation of metabolism in some multicellular organisms, leading to dormancy, or torpor. Colonies of the urochordate Botrylloides leachii enter torpor in response to changes in seawater temperature and may survive ...

Phylogeographic and Morphological Analysis of Botrylloides niger Herdman, 1886 from the Northeastern Mediterranean Sea [PDF]

Diversity, 2023
Botrylloides niger (class Ascidiacea) is an invasive marine filter-feeding invertebrate that is believed to originate from the West Atlantic region. This species of colonial tunicate has been observed in several locations along the coasts of Israel and ...

New Botrylloides, Botryllus, and Symplegma (Ascidiacea: Styelidae) in Coral Reefs of the Southern Gulf of Mexico and Mexican Caribbean Sea

Diversity, 2022
Compound styelid ascidians are distributed in all marine environments and usually exhibit high morphological plasticity and complexity. In particular, Botrylloides, Botryllus, and Symplegma species show high morphological variations leading to confusion ...

Integrin-alpha-6+ Candidate stem cells are responsible for whole body regeneration in the invertebrate chordate Botrylloides diegensis [PDF]

Nature Communications, 2020
Clonal ascidians are able to undergo whole body regeneration (WBR), where entire new bodies can be regenerated from blood vessel fragments. Here, the authors provide evidence in Botrylloides diegensis supporting pou3 and vasa expressing blood-borne cells

Cryptic Diversity and Database Errors Challenge Non-indigenous Species Surveys: An Illustration With Botrylloides spp. in the English Channel and Mediterranean Sea [PDF]

Frontiers in Marine Science, 2019
Molecular tools have been extensively used in recent decades to examine biological invasion processes, and are increasingly being adopted as efficient tools to support non-indigenous species surveys, notably through barcoding approaches, i.e., the use of

Systemic bud induction and retinoic acid signaling underlie whole body regeneration in the urochordate Botrylloides leachi. [PDF]

PLoS Biology, 2007
Regeneration in adult chordates is confined to a few model cases and terminates in restoration of restricted tissues and organs. Here, we study the unique phenomenon of whole body regeneration (WBR) in the colonial urochordate Botrylloides leachi in ...

Cellular aspects of allorecognition in the compound ascidian Botrylloides simodensis [PDF]

Invertebrate Survival Journal, 2014
When colonies of the compound ascidian Botrylloides simodensis contact each other at their cut surfaces, either fusion or rejection occurs. Contact between genetically compatible colonies leads to the complete fusion of their tunics and vasculature ...

Untargeted Metabolomics Yields Insights Into the Lipidome of Botrylloides niger Herdman, 1886, An Ascidian Invading the Mediterranean Sea

Frontiers in Marine Science, 2022
Human-mediated dispersal of alien species in new biogeographic realms is one of the major drivers of biodiversity change in marine ecosystems. Among others, ascidians are invasive species spreading worldwide, thus causing ecological and economic harms in

Behavioural Responses of the Colonial Sea Squirt Botrylloides violaceus Oka to Suspended Food Micro-Particles in Laboratory Cultures

Journal of Marine Science and Engineering, 2020
Violet sea squirts are noteworthy model organisms, because they provide insights into various physiologic processes, including cell senescence, ageing, apoptosis and allorecognition. Consequently, their culture is critical to permit experimental studies.

Possible Evolutionary Precursors of Mast Cells: The ‘Granular Cell’ Immunocyte of Botrylloides leachii (Tunicata; Ascidiacea)

Journal of Marine Science and Engineering
Vertebrate mast cells are the first cells to initiate the inflammatory response. The origin of these highly specialised innate immunity cells in chordates is an intriguing unanswered question, and tunicates represent the best candidates to address this ...
