3 Correlation of gene expression between PC and WT corals
during heat stress. Linear regression model with Pearson correlation
was calculated for mean single gene expression (A) and mean gene
expression ratio (B) of preconditioned (PC) and wild-type (WT) corals
during acute heat stress (32ºC), n = 6. PC corals were exposed to
three-day sublethal temperature (29ºC) and then rested for two weeks at
ambient temperature (26ºC). WT corals were exposed to natural summer
fluctuating oceanic temperatures in Kaneohe Bay, Hawaii with peaks
around 29ºC. Pearson correlation factors show very similar response to
sudden heat stress in both groups of corals pointing to the natural
ability of corals to acclimatize to summer temperatures through
modulations in the signaling pathways.
