The closed nutrient recycling system in the Paramecium-Chlorella photosymbiosis contributes to survival under oligotrophic conditions
Nutrient recycling via farming of Chlorella by Paramecium hosts confers an advantage in oligotrophic environments.

We conclude that symbiosis relies on the function of lysosomal proteins. How the algae resist digestion will require further investigation, but the co-option of lysosomal proteins for symbiosis may provide insight into the repeated evolution of photosymbiosis across animal taxa. 11/12 🧵

Excitingly, we found that mutating this gene in Galaxea also causes a loss of symbiosis, despite the independent evolution of photosymbiosis in these taxa! The defect is likely caused by breaking the supply of inorganic carbon and sulfate to the algae, required for the symbiont to thrive. 10/12 🧵

I just returned from my holiday in Finland. While we were looking for bears, wolves and co, one of my personal favorites were these green-alga bearing freshwater sponges. Photosymbiosis is everywhere if you look close enough. Maybe it‘s time for some freshwater work at @hifmb.de?

... to reconstruct the evolutionary history of the trait, it was found that photosymbiosis is a remarkably stable trait, rarely showing evidence of reversion to a non-symbiotic lifestyle even among corals that acquire symbionts from the environment each generation (doi.org/10.1126/scia...) ..
