Project description:Draft genome of the Symbiodiniaceae Durusdinium trenchii
| PRJDB10306 | ENA
Project description:Samples are from a screening experiment on 5 laboratory cultures of the coral endosymbiont: Symbiodiniaceae (Symbiodinium linuchae, Breviolum psygmophilum, Durusdinium trenchii, Effrenium voratum and Fugacium kawagutii). Samples are also from a thermal stress experiment (increased temperatures from 26 to 32 degrees C) carried out on Durusdinium trenchii and Cladocopium goreaui, two common coral endosymbionts on the Great Barrier Reef. All samples were collected on Markes Tenax TA thermal desorption tubes.

Project description:Cultures of three Symbiodiniaceae genera (Breviolum minutum, Durusdinium trenchii, Cladocopium sp.) were exposed to temperatures increasing from 26C to 32C over three days, followed by one week at 32C. Samples for proteome analysis were taken from controls (26C), at the end of the temperature ramp, and after one week at 32C. The three species have been submitted to PRIDE individually. Manuscript in preparation.

Project description:Cellular mechanisms responsible for the regulation of nutrient exchange, immune responses, and symbiont population growth in the cnidarian-dinoflagellate symbiosis are poorly resolved, particularly with respect to the dinoflagellate symbiont. Here, we characterised proteomic changes in the native symbiont Breviolum minutum during colonisation of its host sea anemone Exaiptasia diaphana (‘Aiptasia’). We also compared the proteome of this native symbiont in the established symbiotic state with that of a non-native symbiont, Durusdinium trenchii. The onset of symbiosis between Aiptasia and B. minutum induced increased accumulation of symbiont proteins associated with acquisition of inorganic carbon and photosynthesis, nitrogen metabolism, micro- and macronutrient starvation, suppression of the host immune responses, tolerance to low pH, and management of oxidative stress. Such responses are consistent with a functional, persistent symbiosis. In contrast, D. trenchii predominantly showed elevated levels of immunosuppressive proteins, consistent with the view that this symbiont is an opportunist that forms a less beneficial, less well-integrated symbiosis with this model anemone. By adding this analyses of the symbiont proteins to the already known responses of the host proteome, our results provide a more holistic view of cellular processes that determine host-symbiont specificity and how differences in symbiont partners, native versus non-native symbionts, may impact the fitness of the cnidarian-dinoflagellate symbiosis in response to thermal stress. This PRIDE entry contains the Breviolum minutum data; Durusdinium trenchii data are uploaded in a separate entry with identical parameters.

Project description:Genome sequencing of symbiotic dinoflagellate Durusdinium trenchii from isolates CCMP2556 and SCF082
| PRJEB66001 | ENA
Project description:We subjected three inshore and four offshore genotypes of the coral Orbicella faveolata to 30, 31, 32, or 33ºC for 31 days and measured photochemical efficiency (Fv/Fm), the types and relative abundance of dinoflagellate endosymbionts, and gene expression of the host and symbiont. All inshore coral genotypes, regardless of symbiont type, were significantly more thermotolerant than offshore genotypes based on declines in Fv/Fm. The most heat-tolerant inshore genotype (In1) was dominated by Durusdinium trenchii; all other genotypes were Breviolum-dominated, suggesting local adaptation or acclimatization contributes to the heat tolerance of inshore genotypes. After 31 days of heat stress, all coral genotypes (except In2) had lost most of their Breviolum and became dominated by D. trenchii. Host genotype In1 presented unique expression patterns of genes involved in heat shock response, immunity, and protein degradation. There were few changes in the symbiont transcriptomes of inshore corals under heat stress, but significant changes in symbiont gene expression from the offshore colonies, including increases in ribosomal and photosynthetic proteins. These data show that the differential thermotolerance between inshore and offshore O. faveolata in the Florida Keys is associated with statistically significant differences in both host and symbiont gene expression that provide insights into the mechanisms underlying holobiont heat tolerance.

Project description:Transcriptional responses to heat stress were assayed in early life-history stages of 11 crosses between and amongst Acropora tenuis colonies originating from reefs along the Great Barrier Reef. We identified a single nucleotide polymorphism outlier (Fst=0.89) between populations in the unannotated gene Acropora25324, which exhibited constitutively higher gene expression in populations with dams originating from Curd reef, a far north, warm adapted inshore reef, suggesting an important role of this gene in adaptation to warmer environments. Further, juveniles exposed to heat and in symbiosis with heat-evolved Symbiodiniaceae displayed intermediate transcriptional responses between its progenitor taxa (Cladocopium goreaui) and the more stress tolerant Durusdinium trenchii, indicating that the development of heat tolerance acquisition is potentially a conserved evolutionary process in Symbiodiniaceae. These findings reveal the underlying mechanisms, and for the first time, their relative contribution, of coral responses to climate change and provide a foundation for optimizing conservation methods like assistant gene flow.
