...Alexander A. Venn; Nathalie Techer; Natacha Segonds; Eric Tambutté; Sylvie Tambutté ABSTRACT Despite its prominent role as an intracellular messenger in all organisms, cytosolic free calcium ([Ca 2+ ] i ) has never been quantified in corals or cnidarians in general. Ratiometric calcium dyes...

... distinct siphonophore jellyfish shows that metachronal coordination of pulsed jets produced by nectophores affects how jet wakes interact, and thus how they may be optimized for propulsion. Cnidarian Jellyfish Metachronal Multi-jet propulsion Zooplankton David and Lucile Packard...

... to bilaterians or was already present in early metazoans. We therefore examined neurite polarity in the starlet sea anemone Nematostella vectensis (Cnidaria). Cnidarians form a sister clade to bilaterians and share many neuronal building blocks characteristic of bilaterians, including channels, receptors...

...Jack Cushman Koch; E. Alan Verde; Virginia M. Weis ABSTRACT Carbonic anhydrases (CA; EC 4.2.1.1) play a vital role in dissolved inorganic carbon (DIC) transport to photosynthetic microalgae residing in symbiotic cnidarians. The temperate sea anemone Anthopleura elegantissima can occur in three...

... Nematostella vectensis exhibits strong circadian behavioral rhythms following entrainment in natural conditions. Corresponding transcriptional rhythms suggest that solar radiation drives physiological cycles in this sediment-dwelling animal. Chronobiology Circadian Cnidarian Entrainment Subtidal UV...

... an important means of neutralizing such oxidants. Studies in cnidarians have previously documented the occurrence of antioxidant enzymes (transcript expression, protein expression and/or enzymatic activity), but most of these studies have not been conducted in species with sequenced genomes or included...

...Julien Laurent; Sylvie Tambutté; Éric Tambutté; Denis Allemand; Alexander Venn SUMMARY The regulation of intracellular pH (pHi) is a fundamental aspect of cell physiology that has received little attention in studies of reef-building corals and symbiotic cnidarians. Here, we investigated...

...Thamilla Zamoum; Paola Furla SUMMARY The presence of photosynthetic zooxanthellae (dinoflagellates) in the tissue of many cnidarians is the main reason for their ecological success (i.e. coral reefs). It could also be the main cause of their demise, as the worldwide bleaching of reef-building coral...

...James L. Dimond; Benjamin J. Holzman; Brian L. Bingham SUMMARY The susceptibility of algal–cnidarian holobionts to environmental stress is dependent on attributes of both host and symbiont, but the role of the host is often unclear. We examined the influence of the host on symbiont light stress...

... electron microscopy reveals that regressing stolons have atypical ultrastructural features. Cell death during regression is suggested by both TUNEL and TEM. These results further support previous work suggesting a potentially large role for ROS and RNS in cnidarian signaling. Several examples...
