Epigenome-associated phenotypic acclimatization to ocean acidification in a reef-building coral
There are increasing concerns that the current rate of climate changemight outpace the ability of reef-building corals to adapt to future conditions. Work on model systems has shown that environmentally induced alterations in DNA methylation can lead to phenotypic acclimatization.WhileDNAmethylation...
