Epigenetic-associated phenotypic plasticity of the ocean acidification-acclimated edible oyster in the mariculture environment
For marine invertebrates with a pelagic-benthic life cycle, larval exposure to ocean acidification (OA) can affect adult performance in response to another environmental stressor. This carry-over effect has the potential to alter phenotypic traits. However, the molecular mechanisms that mediate &quo...

For marine invertebrates with a pelagic-benthic life cycle, larval exposure to ocean acidification (OA) can affect adult performance in response to another environmental stressor. This carry-over effect has the potential to alter phenotypic traits.

This study integrated the genome-wide DNA methylome and transcriptome to examine epigenetic modification-mediated carry-over OA impacts on phenotypic traits of the ecologically and commercially important oyster species Crassostrea hongkongensis under field conditions.
