Lipid nanoparticles are absorbed by the anemone Exaiptasia diaphana and stimulate lipid metabolism, including beta-oxidation and the TCA cycle.

We show that anemones absorb #lipid nanoparticles directly from seawater, stimulating their #metabolism. Details, and potential applications for #coral reef restoration and aquaculture, in our new preprint!

My suspicion is that it contributes heavily to its ability to quickly recolonize post-bleaching, and potentially to its infection of a broad diversity of hosts in the Caribbean.

Sub‐cellular imaging shows reduced photosynthetic carbon and increased nitrogen assimilation by the non‐native endosymbiont Durusdinium trenchii in the model cnidarian Aiptasia Hosting different symbiont species can affect inter-partner nutritional fluxes within the cnidarian–dinoflagellate symbiosis. Using nanoscale secondary ion mass spectrometry (NanoSIMS), we measured t....

Possibly. We've got a previous paper showing that Durusdinium is better at acquiring nitrogenous compounds from the host, which may be a mechanism of how it escapes host control: enviromicro-journals.onlinelibrary.wiley.com/doi/abs/10.1...

Cell cycle arrest in the cnidarian-dinoflagellate symbiosis.

Corals maintain stable populations of essential photosynthetic symbionts by controlling their cell cycle, not by eating them! Our new #PNAS paper monitored and modelled #aiptasia cell cycle, autophagy, and expulsion for over a year. #symbiosis #microbiology www.pnas.org/doi/10.1073/...

The Influence of Symbiont Identity on the Proteomic and Metabolomic Responses of the Model Cnidarian Aiptasia to Thermal Stress We examined the effects of symbiont identity and heat stress on the host metabolome and proteome in the cnidarian–dinoflagellate symbiosis. Integrated metabolome and proteome analyses characterised h...

How can new heat-resistant algae help host metabolism and immunity during #coralbleaching? Do they become better partners over time? Our new paper (tinyurl.com/465k5hpx) uses combined #proteomics and #metabolomics to show how they help their hosts, or not, during thermal stress. #microbiology

Coral reefs in Vietnam face collapse. Can conservation efforts turn the tide? The coral reefs of Nha Trang, Vietnam, are in severe decline due to climate change, overfishing, and pollution.

Moko, an 800 year old rimu tree.

This is Moko, an 800-year-old rimu in Ōtari-Wilton's Bush in Wellington. Enormous, covered in epiphytes, and very near the city center!

Immunocytochemistry fluorescent microscopy image showing the localisation of different oxylipin receptors in the anemone Exaiptasia diaphana.

Andrea's new paper explores oxylipin receptors in the coral symbiosis and how they may be important for the stability and the functional biology of coral reefs. Congrats Andrea!

Reef Futures conference poster session

The methods and scale of coral reef restoration efforts have advanced immensely in the past few years, some of these tools are amazing. Enjoying learning about the latest global efforts at #ReefFutures !

But of course you're familiar with Aiptasia! :)

Aiptasia Symbiosis Resource Supporting a collaborative understanding of the mechanisms behind coral symbiosis

Exaiptasia diaphana ('Aiptasia'), a symbiotic anemone and model for the coral-dinoflagellate symbiosis. Great in the lab and you can do lots of good undergrad work with it. aiptasia-resource.org

Hi, yes please, thanks for organizing.

Hi #TeamMassSpec: For those of you on the facility management side of the party, how do you go about finding potential #proteomics clients/customers, either academic or commercial? We're considering new strategies.

Hi, I'd love to be included!

Hi Monica, please add me and thanks for setting this up.

Looks like a good list to be on! Please add me when you have a chance.

Summary of proteomic changes in Breviolum minutum and Durusdinium trenchii during symbiosis establishment with the anemone Exaiptasia diaphana.

We detailed how dinoflagellate proteomes shift over time during symbiosis establishment, and contrasted physiological and immune pathways in successful and opportunistic symbionts. See our new paper in ISMEJ! academic.oup.com/ismej/advanc...
