A gonad-expressed opsin mediates light-induced spawning in the jellyfish Clytia
Across the animal kingdom, environmental light cues are widely involved in regulating gamete release, but the molecular and cellular bases of the photoresponsive mechanisms are poorly understood.

A maternally localised Wnt ligand required for axial patterning in the cnidarianClytia hemisphaerica [PDF]
Regionalised activation of canonical Wnt signalling via β-catenin stabilisation is a key early step in embryonic patterning in many metazoans,including the basally diverging cnidarians, but the upstream maternal cues appear surprisingly variable. In Clytia, regionalised β-catenin stabilisation defining a presumptive `oral' territory is determined by ...

Managing the Oocyte Meiotic Arrest—Lessons from Frogs and Jellyfish
During oocyte development, meiosis arrests in prophase of the first division for a remarkably prolonged period firstly during oocyte growth, and then when awaiting the appropriate hormonal signals for egg release. This prophase arrest is finally unlocked

Effects of ocean acidification (OA) on the plant phenology and colonization/settlement pattern of the hydrozoan epibiont community of the leaves of the seagrass Posidonia oceanica have been studied at volcanic CO2 vents off Ischia (Italy).

The genome of the jellyfish Clytia hemisphaerica and the evolution of the cnidarian life-cycle [PDF]
Jellyfish (medusae) are a distinctive life-cycle stage of medusozoan cnidarians. They are major marine predators, with integrated neurosensory, muscular and organ systems. The genetic foundations of this complex form are largely unknown. We report the draft genome of the hydrozoan jellyfish Clytia hemisphaerica and use multiple transcriptomes to ...

A systematic account is provided of the siphonophores, medusae, ctenophores, molluscs and salps net-collected in basins of the Gulf of Maine and adjacent canyons during three cruises carried out in September 2002, 2003 and 2004.

Comparative study of Hippo pathway genes in cellular conveyor belts of a ctenophore and a cnidarian
Background The Hippo pathway regulates growth rate and organ size in fly and mouse, notably through control of cell proliferation. Molecular interactions at the heart of this pathway are known to have originated in the unicellular ancestry of metazoans ...

Distinct gelatinous zooplankton communities across a dynamic shelf sea
Abstract Understanding how gelatinous zooplankton communities are structured by local hydrography and physical forcing has important implications for fisheries and higher trophic predators. Although a large body of research has described how fronts, hydrographic boundaries, and different water masses (e.g., mixed vs. stratified) influence phytoplankton

Restriction of proteins to discrete subcellular regions is a common mechanism to establish cellular asymmetries and depends on a coordinated program of mRNA localization and translation control. Many processes from the budding of a yeast to the establishment of metazoan embryonic axes and the migration of human neurons, depend on this type of cell ...
