Reconstructing the gene regulatory network that shaped the evolution of larval sensory structure with a long ciliary tuft in Cnidaria.

(Submitter supplied) Cnidarians are the only non-bilaterian group to evolve ciliated larvae with an apical sensory organ integrated with neurons, possibly homologous to the bilaterians. Within cnidarians, an apical organ with a ciliary tuft is identified only in sea anemones. Whether this apical tuft has evolved independently in anthozoans or alternatively originated in the eumetazoans and was lost independently in specific groups of cnidarians and bilaterians is uncertain.

Mixed patterns of intergenerational DNA methylation inheritance in Acropora

(Submitter supplied) For sessile organisms at high risk from climate change, phenotypic plasticity can be critical to rapid acclimation. Epigenetic markers like DNA methylation are hypothesized as mediators of plasticity; methylation is associated with the regulation of gene expression, can change in response to ecological cues, and is a proposed basis for the inheritance of acquired traits. Within reef-building corals, gene body methylation can change in response to ecological stressors. more...

3D genomics across the tree of life reveals condensin II as a determinant of architecture type

(Submitter supplied) We investigated genome folding across the eukaryotic tree of life. We find four general manifestations of genome organization at chromosome-scale that each emerge and disappear repeatedly over the course of evolution. The submission represents chromosome-length Hi-C contact maps, architecture type and homolog separation analyses for 26 species across the tree of life, representing all subphyla of chordates, all 7 extant vertebrate classes, and 7 out of 9 major animal phyla, as well as plants and fungi.

Transcriptomic analysis of the response of Acropora millepora to hypo-osmotic stress provides insights into DMSP biosynthesis by corals

(Submitter supplied) Purpose: Corals are major sources of dimethylsulphoniopropionate (DMSP), a compound that plays a central role in the global sulphur cycle. While DMSP biosynthesis pathways have been investigated in plants and algae, the molecular basis for its production by corals is unknown. Given its potential role as an osmolyte, the effect of salinity stress on levels of DMSP was investigated in both adults and juveniles (lacking photosynthetic symbionts) of the coral Acropora millepora. more...

Transcriptomic differences between day and night in Acropora millepora provide new insights into metabolite exchange and light-enhanced calcification in corals

(Submitter supplied) The metabolic bases of the interaction between the coral Acropora millepora and its dinoflagellate symbiont were investigated by comparing gene expression levels under light and dark conditions at the whole transcriptome level. Among the differentially expressed genes identified, a suite of genes involved in cholesterol transport was found to be up-regulated under light conditions, confirming the significance of this compound in the coral symbiosis. more...

The acute transcriptional response of the coral Acropora millepora to immune challenge: expression of GiMAP/IAN genes links the innate immune response of corals with those of mammals and plants

(Submitter supplied) This studies investigates the acute response of the coral Acropora millepora to two immunogenes: MDP (bacterial mimic) and pIC (viral mimic). Three members of the GiMAP familly were found to respond strongly to MDP treatment, showing analalogy to the immune response in vertebrates and plants.

High natural gene expression variation in the reef-building coral Acropora millepora: Potential for acclimative and adaptive plasticity

(Submitter supplied) This experiment assessed the natural gene expression variation present between colonies of the Indo-Pacific reef-building coral Acropora millepora, and additionally explored whether gene expression differed between two different intron haplotypes according to intron 4-500 in a carbonic anhydrase homolog. This study found no correspondence between host genotype and transcriptional state, but found significant intercolony variation, detecting 488 representing unique genes or 17% of the total genes analyzed. more...

Coral thermal tolerance: tuning gene expression to resist thermal stress

(Submitter supplied) Thermal history plays a role in the response of corals to subsequent heat stress. Prior heat stress can have a profound impact on later thermal tolerance, but the mechanism for this plasticity is not clear. The understanding of gene expression changes behind physiological acclimatization is critical in forecasts of coral health in impending climate change scenarios. Acropora millepora fragments were preconditioned to sublethal bleaching threshold stress for a period of 10 days; this prestress conferred bleaching resistance in subsequent thermal challenge, in which non-preconditioned coral bleached. more...

Acropora millepora adult samples: Control vs medium and high ocean acidification treatment

(Submitter supplied) In this study we investigated how changes in pH and ocean chemistry consistent with the scenarios of the Intergovernmental Panel on Climate Change (IPCC) drive major changes in gene expression, respiration, photosynthesis and symbiosis of the coral, Acropora millepora, long before they affect biomineralization. Changes in gene expression were consistent with metabolic suppression, an increase in oxidative stress, apoptosis and symbiont loss. more...

Circadian regulation of gene expression in the coral algal endosymbiosis

(Submitter supplied) Despite their early evolutionary divergence, reef-building corals exhibit complex circadian responses to diurnal, lunar and annual changes in the conditions around them. Understanding circadian regulation in reef-building corals is, however, complicated by the presence of photosynthetic endosymbionts that have a profound physiochemical influence on the intracellular environment. How corals tune their animal-based clock machinery to respond to external cues while at the same time responding to internal physiological changes imposed by the symbiont is not clear. more...

Molecular response of the coral Acropora millepora to three settlement and/or metamorphosis induced stimuli

(Submitter supplied) Two known settlement/metamorphosis inducing stimuli (crustose coralline algae, and ethanolic extract of crustose coralline algae) and one stimulus which just induces metamorphosis (LWamide) were used to stimulate competent planula larvae of the coral Acropora millepora. Samples were taken 0.5h, 4h and 12h post induction isolate the genes controlling settlement and metamorphosis in this coral.

Early Transcriptomic response of coral larvae to hyperthermal stress

(Submitter supplied) In this study, we examined the very early transcriptional response of aposymbiotic coral larval host (still not engaged in symbiosis) to hyperthermal stress. This experimental setting provided a scenario and opportunity to study the direct effect of environmental stressors on the host cell per se. Using a cDNA microarray constructed for Acropora millepora and Q-RT-PCR assays, we identified a number of genes that were significantly up- and down-regulated with increase of seawater temperature. more...

Microarray analysis identifies candidate genes for key roles in coral development

(Submitter supplied) Background: Anthozoan cnidarians are amongst the simplest animals at the tissue level of organization, but are surprisingly complex and vertebrate-like in terms of gene repertoire. As major components of tropical reef ecosystems, the stony corals are anthozoans of particular ecological significance. To better understand the molecular bases of both cnidarian development in general and coral-specific processes such as skeletogenesis and symbiont acquisition, microarray analysis was carried out through the period of early development – when skeletogenesis is initiated, and symbionts are first acquired. more...
