Sibling species differently distributed around a CO₂ vent show transplantation proteomic remodelling, while displaying metabolomic signatures associated with their origin.

ABSTRACT: The cellular homeostatic response (CHR) and cellular stress response (CSR) work together to maintain homeostasis. Studying phylogenetically closely-related species inhabiting different environments can help investigate the interplay between the CHR and CSR. We conducted reciprocal in situ transplant experiments in a natural CO₂ vent (Ischia, Italy), using the sibling annelid species Platynereis cf.. dumerilii and Platynereis cf.. massiliensis which have been shown to have different preferential distributions around the CO₂ vent. Following transplantations, we characterised the response of each individual's proteome, metabolome, and lipidome, to short or long-term exposure to different pCO₂ regimes (i.e., high and low), and confirmed its genetic identity.
