(Submitter supplied) Using transcriptomics, we show that Symbiodinium acclimation to elevated temperature involves up-regulated expression of meiosis genes followed by up-regulated expression of numerous reactive oxygen species scavenging genes and molecular chaperone genes. Our study connects Symbiodinium transcriptional regulation with physiological heat stress responses as well as known bleaching responses of corals harboring these same Symbiodinium. more...

(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) 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...

(Submitter supplied) Symbiodinium, the dinoflagellate photosymbiont of corals, is posited to become more susceptible to viral infections when heat-stressed. To investigate this hypothesis, we mined transcriptome data of a thermo-sensitive and a thermo-tolerant type C1 Symbiodinium population at ambient (27°C) and elevated (32°C) temperatures. We uncovered hundreds of transcripts from nucleocytoplasmic large double-stranded DNA viruses (NCLDVs) and the genome of a novel positive-sense single-stranded RNA virus (+ssRNAV). more...

(Submitter supplied) Animal and plant genomes produce numerous small RNAs (smRNAs) regulating gene expression affecting metabolism, development, and epigenetic inheritance. In order to characterize the repertoire of endogenous microRNAs and potential gene targets, we conducted smRNA and mRNA expression profiling over nine experimental treatments of cultures from the dinoflagellate Symbiodinium sp.
