Abstract Thermal priming of reef corals can enhance their heat tolerance; however, the legacy effects stress during parental brooding on larval resilience remain understudied. This study investigated whether preconditioning adult coral Pocillopora damicornis to high temperatures (29°C and 32°C) could better prepare larvae for stress. Results showed that heat‐acclimated adults brooded with reduced symbiont density shifted thermal performance curves. Reciprocal transplant experiments demonstrated higher bleaching resistance photosynthetic autotrophic in heat‐exposed from acclimated compared unacclimated adults. RNA‐seq revealed strong cellular responses have been effective rescuing host cells stress, as evidenced by widespread upregulation genes involved cell cycle mitosis. For symbionts, a molecular coordination between light harvesting, photoprotection carbon fixation was detected adults, which may help optimize activity yield under temperature. Furthermore, acclimation led opposing regulations catabolic anabolic pathways favoured nutrient translocation thus functional symbiosis. Notwithstanding, improved tolerance paralleled light‐enhanced dark respiration, indicating metabolic depression energy saving. Our findings suggest rapidly shift provide integrated physiological evidence this adaptive plasticity, increase climate resilience. However, be maladaptive long‐term organismal performance, highlighting importance curbing emissions protect corals.

Rampant coral disease, exacerbated by climate change and other anthropogenic stressors, threatens reefs worldwide, especially in the Caribbean. Physically isolated yet genetically connected such as Flower Garden Banks National Marine Sanctuary (FGBNMS) may serve potential refugia for degraded Caribbean reefs. However, little is known about mechanisms trade-offs of pathogen resistance reef-building corals. Here, we measure Montastraea cavernosa from FGBNMS. We identified individual colonies that demonstrated or susceptibility to Vibrio spp. a controlled laboratory environment. Long-term growth patterns suggest no trade-off between disease calcification. Predictive (pre-exposure) gene expression highlights subtle differences resistant susceptible genets, encouraging future studies investigate associations replicative age immune cell populations. associated with long-term underscores role transmembrane proteins involved adhesion cell–cell interactions, contributing growing body knowledge surrounding genes influence calcification Together these results demonstrate genets sanctuaries FGBNMS can withstand challenges potentially aid restoration efforts Furthermore, signatures help inform strategic assessment health parameters.
