Why Homoscleromorph Sponges Have Ciliated Epithelia: Evidence for an Ancestral Role in Mucociliary Driven Particle Flux

V Price, Anudi Nanayakkara, Andrea Pasini, Elsa Bazellières et autres

Cilia are found on the epithelia of almost all metazoans, so their absence from the epithelia of all but one class of Porifera is puzzling. Homoscleromorph sponges possess ciliated epithelia, but their function and evolutionary history within Porifera are unclear. We compared …

The Buds of Oscarella lobularis (Porifera, Homoscleromorpha): A New Convenient Model for Sponge Cell and Evolutionary Developmental Biology

Caroline Rocher, Amélie Vernale, Laura Fierro‐Constaín, Nina Séjourné et autres

The comparative study of the four non-bilaterian phyla (Cnidaria, Placozoa, Ctenophora, and Porifera) provides insights into the origin of bilaterian traits. To complete our knowledge of the cell biology and development of these animals, additional non-bilaterian models are needed. Given the developmental, …

L’éponge marine Oscarella lobularis un modèle pour comprendre l’origine et l’évolution des épithéliums

Emmanuelle Renard, Quentin Schenkelaars, Caroline Rocher, Amélie Vernale et autres

Afin d’émettre des hypothèses sur l’origine et l’évolution des épithéliums, nous développons un modèle d’éponge appartenant à la classe des homoscléromorphes. Les éponges sont l’une des lignées ayant émergé le plus précocement au cours de l’évolution des animaux, elles constituent donc un …

The compact genome of the sponge Oopsacas minuta (Hexactinellida) is lacking key metazoan core genes

Sébastien Santini, Quentin Schenkelaars, Cyril Jourda, Marc A. Duchesne et autres

BACKGROUND: Explaining the emergence of the hallmarks of bilaterians is a central focus of evolutionary developmental biology-evodevo-and evolutionary genomics. For this purpose, we must both expand and also refine our knowledge of non-bilaterian genomes, especially by studying early branching animals, in particular …

The compact genome of the sponge Oopsacas minuta (Hexactinellida) is lacking key metazoan core genes

Sébastien Santini, Quentin Schenkelaars, Cyril Jourda, Marc Duschene et autres

ABSTRACT Background Bilaterian animals today represent 99% of animal biodiversity. Elucidating how bilaterian hallmarks emerged is a central question of animal evo-devo and evolutionary genomics. Studies of non-bilaterian genomes have suggested that the ancestral animal already possessed a diversified developmental toolkit, including …

The Homoscleromorph Sponge, Oscarella lobularis

Emmanuelle Renard, Caroline Rocher, Alexander V. Ereskovsky, Carole Borchiellini

The last 20 years have shown a growing interest in developing non-conventional models for evo-devo purposes. In particular, the study of non-bilaterian metazoans offers the invaluable possibility to explore the origin of key bilaterian morpho-anatomical features, such as the presence of a …

Evolution of mechanisms controlling epithelial morphogenesis across animals: new insights from dissociation-reaggregation experiments in the sponge Oscarella lobularis

Amélie Vernale, Maria Mandela Prünster, Fabio Marchianò, Henry Debost et autres

BACKGROUND: The ancestral presence of epithelia in Metazoa is no longer debated. Porifera seem to be one of the best candidates to be the sister group to all other Metazoa. This makes them a key taxon to explore cell-adhesion evolution on animals. …

Porifera (Sponges): Recent Knowledge and New Perspectives

Carole Borchiellini, Kassandra de Pao Mendonca, Amélie Vernale, Caroline Rocher et autres

Abstract Porifera, commonly named sponges, are devoid of head, digestive tract, nervous system, muscles or any other organs. Despite this anatomical and morphological simplicity, they are true animals or metazoans. Sponges are a successful group of mostly marine filter feeders that represent …
