(Submitter supplied) Background: Cnidarian – dinoflagellate intracellular symbioses are one of the most important mutualisms in the marine environment. They form the trophic and structural foundation of coral reef ecosystems, and have played a key role in the evolutionary radiation and biodiversity of cnidarian species. Despite the prevalence of these symbioses, we still know very little about the molecular modulators that initiate, regulate, and maintain the interaction between these two different biological entities. more...

(Submitter supplied) Transcriptional comparison between endodermal and ectodermal compartment in symbiotic sea anemones Anemonia viridis were analysed in several specimens. We generated an oligonucleotide microarray (2000 selected features), which is to date the only available oligonucleotide array for symbiotic cnidarians. We were able to identify a subset of genes clearly involved in symbiosis.

(Submitter supplied) Coral reefs are based on the symbiotic relationship between corals and photosynthetic dinoflagellates of the genus Symbiodinium. We followed gene expression of coral larvae of Acropora palmata and Montastraea faveolata after exposure to Symbiodinium strains that differed in their ability to establish symbioses. We show that the coral host transcriptome remains almost unchanged during infection by competent symbionts, but is massively altered by symbionts that fail to establish symbioses. more...

(Submitter supplied) Differential expression between endodermal (zooxanthellate) and ectodermal tissue layers in the endosymbiotic sea anemone Anemonia viridis has been analyzed for 3 specimens subjected to a thermal stress (+10°C) for a 2 days period. A symbiosis-dedicated oligonucleotide microarray (2000 selected features) was generated, representing to date the only available oligonucleotide array used for symbiotic cnidarians (GPL10546). more...

(Submitter supplied) We monitored gene expression response of the symbiotic sea anemone Anemonia viridis subjected to a thermal and/or UV stress. A symbiosis-dedicated oligonucleotide microarray (2000 selected features) was generated, representing to date the only available oligonucleotide array used for symbiotic cnidarians (GPL10546). We are describing here the expression evolution during the first phase (5 days) of the stress.

(Submitter supplied) A mutualistic relationship between reef-building corals and endosymbiotic algae (Symbiodinium spp.) forms the basis for the existence of coral reefs. Genotyping tools for Symbiodinium spp. have added a new level of complexity to studies concerning cnidarian growth, nutrient acquisition, and stress. For example, the response of the coral holobiont to thermal stress is connected to the host-Symbiodinium genotypic combination, as different partnerships can have different bleaching susceptibilities. more...

(Submitter supplied) Given the overwhelming evidence that symbiont genotypes differentially affect host processes such as growth, bleaching susceptibility, and nutrient acquisition, we set out to measure gene expression differences in fragments of Montastraea faveolata harboring two different clades of Symbiodinium. On the reefs near Puerto Morelos, México, colonies of M. faveolata are known to shift algal symbiont clade with depth, often associating with clade A at the top, clade B in the middle, and clade C near the bottom of the colony. more...

(Submitter supplied) Emergence of the symbiotic lifestyle fostered the immense diversity of all ecosystems on Earth, but symbiosis plays a particularly remarkable role in marine ecosystems. Photosynthetic dinoflagellate endosymbionts power reef ecosystems by transferring vital nutrients to their coral hosts. The mechanisms driving this symbiosis, specifically those which allow hosts to discriminate between beneficial symbionts and pathogens, are not well understood. more...

(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...
