Rapid compensatory evolution can rescue low fitness symbioses following partner switching (Current Biology)
Rapid compensatory evolution can rescue low fitness symbioses following partner switching (Current Biology)

Highlights

  • •Partner-switches show intergenomic epistasis in the Paramecium-Chlorella symbiosis

  • •Low fitness host-symbiont pairings show elevated symbiont stress metabolites

  • •Poorly performing pairings rapidly gain higher fitness by compensatory evolution

  • •Compensatory evolution could arise by either host or symbiont adaptation

A thesis published by AMRI member Eva Sörenson (LNU) in fall 2020 has bee featured in Havet, the publication on all of the latest marine research: https://www.havet.nu/samspel-bland-mikrober

Eva’s thesis explored the interplay of bacteria and phytoplankton in the microbial world - that they cooperate with each other instead of compete with each other.
