Corals internalise algae into their cells to form a symbiosis that underpins reef ecosystems. How does the host integrate symbionts into its body plan? Happy to share our preprint: Symbiont spatial organisation is dynamically regulated within cnidarian host tissues. doi.org/10.64898/202...

We now hypothesize that this symbiosis (and perhaps others) evolved by the algae resisting digestion by coral cells. To quote @pcleves.bsky.social, the algae may be acting as an "everlasting gobstopper" - a food particle that keeps on giving. Perhaps symbiosis fails when the algae stop giving (6/7)

We realized that the lysosome is actually a decent place to be if you're an algae trying to photosynthesize. The acidic properties of the lysosome and its bicarbonate transporters can work together to concentrate inorganic carbon for photosynthesis. You just need to resist digestion. (5/7)

It had long been hypothesized that the symbiosome forms by preventing fusion with lysosomes, but we found the exact opposite. Instead we found that symbiosis relies on the proper function of lysosomal proteins, such as SLC26A11, and that the symbiosome recruits several digestive enzymes. (4/7)

Through careful proteomics, microscopy, RNAi, and CRISPR/Cas9-mutagenesis experiments, we identified that the symbiont-housing organelle forms through fusion with lysosomes - where things are usually digested. We were very surprised by this. (3/7)

Several coral lineages have independently evolved symbioses with photosynthetic algae, allowing them to thrive in the tropics and build the world's reefs. These algae live inside of host cells within compartments called symbiosomes. But its cellular origins had long remained a mystery. (2/7)
