Overview

Randomized trial investigates coral gene expression in response to ocean conditions, suggesting symbiotic relationships shape resilience.

Key Points

  • This research examines how Caribbean coral Siderastrea siderea responds to climate change effects on gene expression and holobiont phenotypes.
  • Examined coral Siderastrea siderea under simulated future ocean conditions for three months
  • Analyzed holobiont phenotypes and gene expression profiles
  • Assessed microbial communities in response to various acidification and warming scenarios.
  • Corals hosting Durusdinium trenchii had higher lipid content but lower calcification rates compared to those with Cladocopium goreaui
  • Significant changes in holobiont phenotype and gene expression occurred mainly under extreme acidification conditions
  • Moderate stress responses were observed in S. siderea with no shifts in symbiotic communities under typical future scenarios.
