What extreme physiologies does the painted turtle genome encode?
Open access · cc by · source: Europe PMC
The western painted turtle genome informs evolution of extreme anoxia and freeze tolerance in a slowly evolving vertebrate lineage.
Key findings
Genome resources for one of the most anoxia-tolerant tetrapods, capable of freezing nearly solid then thawing with little damage; molecular adaptations for winter survival.
Methodology
Sequenced/analyzed Chrysemys picta genome in the context of anoxia and freeze-survival physiology.
Limitations
Does not by itself map every protective pathway experimentally.

Role on claims
Each row is a claim on a concept or method page where this paper supports, challenges, or qualifies the statement. Roles are hand-checked — not a model guess.
Whole-genome papers for extreme physiology use phylogeny as context rather than as the sole result. The painted-turtle genome is a resource for anoxia and freeze-survival in a tetrapod that can freeze nearly solid then thaw with little damage; the wild Medicago ruthenica assembly is compared with cultivated legumes to retain stress-tolerance traits diluted by domestication. Neither map every protective pathway experimentally or deliver a finished cultivar.
Evidence for the claim as stated.
