Paradoxical role of new endosymbiotic associations: they facilitate the emergence of new partnerships, but inhibit deeper integration between hosts and guests (by favoring uncoordinated reproduction over synchronized ones). That is, easy come, easy go. #Endosymbiosis doi.org/10.1101/2025...

Currency exchange in endosymbiosis: early on, hosts’ investments generate a fortune in guest growth; near full reproductive synchronization, that same investment buys much less. That is, cheap early gains, expensive late ones. #Endosymbiosis #tradeoffs doi.org/10.1101/2025...

This work stems from the “Theory of Microbial Symbiosis” workshop held last year at HIMB (Hawaiʻi Institute of Marine Biology), supported by the Gordon and Betty Moore Foundation @moorefound.bsky.social. Grateful to Joan Roughgarden and Lisa McManus for organizing such a fantastic workshop!

We discuss the limits of current theoretical host-microbe models and outline 3 key areas for future work: 1) Modelling the nested structure of holobionts 2) Capturing microbial transmission dynamics in #holobiont populations 3) Understanding symbiont-driven host evolution and speciation
The top of the image shows a coral reef with a zoomed-in section highlighting the coral holobiont (comprising coral cells, bacteria, phages, fungi, and zooxanthellae). Below each component is its genetic material, collectively forming the "hologenome."

At the bottom, a wasp is shown as another example of a holobiont. On the left, the wasp hosts symbionts such as bacteria and phages. In the center, two wasps share some symbionts with each other and the environment. On the right, a wasp lineage undergoes speciation, resulting in two wasp species, each with a distinct symbiont composition.

Impaired photoacclimation in a kleptoplastidic dinoflagellate reveals physiological limits of early stages of endosymbiosis
Dinophysis dinoflagellates use plastids stolen from prey. Garric et al. show that these plastids cannot synthesize a complete phycoerythrin, a crucial photosynthetic protein. Dinophysis thus relies on prey ingestion for photoacclimation. It is noteworthy that some Dinophysis have acquired phycoerythrin synthesis genes from cryptophytes during evolution.
