Study TitleA carbon-nitrogen negative feedback loop underlies the repeated evolution of cnidarian-Symbiodiniaceae symbioses across >700 Myr
Study SummarySymbiotic associations with Symbiodiniaceae have evolved independently across a diverse range of cnidarian taxa including reef-building corals, sea anemones, and jellyfish, yet the molecular mechanisms underlying their regulation and repeated evolution are still elusive. Here we show that despite their independent evolution, cnidarian hosts employ the same carbon-nitrogen negative feedback loop to control symbiont proliferation. Symbiont-derived photosynthates are used to assimilate nitrogenous waste via GS/GOGAT mediated amino acid biosynthesis in a carbon dependent manner, which regulates the availability of nitrogen to the symbionts. Using nutrient supplementation experiments, we show that the provision of additional carbohydrates significantly reduces symbiont density while ammonium promotes symbiont proliferation. UHPLC-HR-MS analysis confirmed that all hosts co-incorporated glucose-derived 13C and ammonium-derived 15N via GS/GOGAT mediated amino acid biosynthesis. Our results reveal a general carbon-nitrogen negative feedback loop underlying these symbioses and provide a parsimonious explanation for their repeated evolution.

Collection ID:CO002975
Collection Summary:Coral fragments and jellyfish were collected from the Red Sea and maintained in the lab for more than 6 months before the experiment. Sea anemone Exaiptasia were maintained in the lab for more than 5 years before the experiment.
Sample Type:Whole invertebrate animal

Treatment:

Treatment ID:TR002991
Treatment Summary:S. pistillata fragments, symbiotic and aposymbiotic E. diaphana polyps, and C. andromeda at the medusa stage were incubated for 48 hours with either filtered seawater, filtered seawater with 10 mM 13C6-glucose, filtered seawater with 250 µM 15N-ammonium, or filtered seawater and 10 mM 13C6-glucose and 250 µM 15N-ammonium.

Sample Preparation:

Sampleprep ID:SP002988
Sampleprep Summary:Animal tissue homogenates were lysed in 5 ml milli-Q water and lyophilized using a freeze dryer (Labconco). The lyophilisates were resuspended in 1 ml pre-chilled (-20 ℃) 100% methanol, sonicated for 30 minutes at 4 ℃ in an ultrasonication bath (Branson), and centrifuged at 3,000g for 30 minutes at 4 ℃. The supernatants were collected and stored in -80 ℃. The pellets were resuspended in 1 ml 50% methanol (-20 ℃) and centrifuged at 3,000g for 30 minutes at 4 ℃. The supernatants were then combined with those collected from the previous step. The total extracts were then centrifuged at 16,000g for 15 minutes at 4 ℃ to remove any potential particulates. The supernatants were dried using a speed vacuum concentrator (Labconco) and stored at -80 ℃ until further processing.
