Chilling injury to algal symbionts induces host starvation and metabolic reorganization in a temperate cnidarian
This study reveals that cold stress destabilizes the cnidarian-algal symbiosis in the sea anemone *Aiptasia couchii* by causing chilling injury to algal symbionts, which disrupts photosynthetic carbon cycling and ultimately leads to host starvation through metabolic reorganization and protein catabolism.
