Developmental Biology, 2006 This issue of Developmental Biology features articles that constitute a new wave of insights into how a genome interacts with itself (as DNA) and with effectors-proteins and probably RNAs, collectively operating as a kind of "cis-trans" dualism. We learned a test for allelism in genetics class that bore that Latin name but now it comes as a new day for

On artificial parthenogenesis in sea-urchins. [PDF]
Science, 1900 IN No. 277 of SCIENCE, I stated that the MgCl 2 solution used in my experiments on artificial parthenogenesis was a 20/8 n solution. I have since found that the assistant who made the Mg-solution used and who has left the laboratory must have made a mistake as the solution contained only ...

Characterization of sea-urchin fibronectin [PDF]
Biochemical Journal, 1983 Sea-urchin fibronectin from the ovary of the sea urchin Pseudocentrotus depressus bound to gelatin, fibrin and fibrinogen. After mild digestion of the protein labelled with 125I, a 195 000 Da domain was observed. Sea-urchin fibronectin was aggregated by spermine (1 mM) at neutral pH.

Functional traits of two co-occurring sea urchins across a barren/forest patch system [PDF]
, 2013 Temperate rocky reefs may occur in two alternative states (coralline barrens and erect algal forests), whose formation and maintenance are often determined by sea urchin grazing.

Sea urchin roe quality within urchin barrens and improvement through kelp restoration
EcosphereSea urchin overgrazing is a major cause of kelp loss and consequently sea urchin removal is frequently promoted as a tool for restoring kelp in urchin barrens. While many sea urchin species support high‐end roe fisheries, roe condition is generally lower

Beyond the Nature-Culture Frontier
Journal of Festive Studies, 2021 In order to challenge the culture–nature dichotomy, this article investigates two festivities centered around fishing and consuming the sea urchin in two different locations: the Suape Bay Ouriçada (Brazil) in the Southern Hemisphere, and the Carry-le ...

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

Karyotyping and localization of genes on the chromosomes of the sea urchins, Strongylocentrotus drobachiensis and Strongylocentrotus purpuratus [PDF]
, 2009 The purple sea urchin, Strongylocentrotus purpuratus , is an important model for probing gene interactions during animal development and is the only non-chordate deuterostome for which a complete genome sequence is available.

Identification and characterization of PlAlix, the Alix homologue from the Mediterranean sea urchin Paracentrotus lividus. [PDF]
, 2013 The sea urchin provides a relatively simple and tractable system for analyzing the early stages of embryo development. Here, we use the sea urchin species, Paracentrotus lividus, to investigate the role of Alix in key stages of embryogenesis, namely the ...
