Phylogenomics of strongylocentrotid sea urchins [PDF]
BMC Evolutionary Biology, 2013 Strongylocentrotid sea urchins have a long tradition as model organisms for studying many fundamental processes in biology including fertilization, embryology, development and genome regulation but the phylogenetic relationships of the group remain largely unresolved. Although the differing isolating mechanisms of vicariance and rapidly evolving gamete

RNA-Seq identifies SPGs as a ventral skeletal patterning cue in sea urchins [PDF]
, 2016 The sea urchin larval skeleton offers a simple model for formation of developmental patterns. The calcium carbonate skeleton is secreted by primary mesenchyme cells (PMCs) in response to largely unknown patterning cues expressed by the ectoderm.

The challenge of managing the commercial harvesting of the sea urchin Paracentrotus lividus: advanced approaches are required [PDF]
PeerJ, 2020 Sea urchins act as a keystone herbivore in marine coastal ecosystems, regulating macrophyte density, which offers refuge for multiple species. In the Mediterranean Sea, both the sea urchin Paracentrotus lividus and fish preying on it are highly valuable ...

A basal deuterostome genome viewed as a natural experiment [PDF]
, 2007 With the determination of its genome sequence the utility of the sea urchin model system increases. The phylogenetic position of the sea urchin among the deuterostomes allows for informative comparisons to vertebrate research models.

Grazing in the dark: A behavioural adjustment in a population of the black sea urchin Arbacia lixula
Ecology and Evolution, 2023 In Mediterranean rocky shores, the black sea urchin Arbacia lixula is often associated with communities dominated by encrusting corallines, devoid of fleshy algae.

The Genome of the Sea Urchin Strongylocentrotus purpuratus [PDF]
Science, 2006 We report the sequence and analysis of the 814-megabase genome of the sea urchin Strongylocentrotus purpuratus , a model for developmental and systems biology. The sequencing strategy combined whole-genome shotgun and bacterial artificial chromosome (BAC) sequences. This use of BAC clones,

Antibacterial and Antioxidant Characteristics of Pigments and Coelomic Fluid of Sea Urchin, Echinodermata Mathaei Species, from the Persian Gulf [PDF]
, 2016 Background & Aims: Sea urchin immune responses are directly exposed to potentially pathogenic microorganisms and develop defence responses mainly based on immunocytes and humoral factors contained in the coelomic fluid.
