Researchers use DNA sequencing to learn why some corals are more heat tolerant

(Phys.org)—Researchers working out of the Hopkins Marine Station at Stanford University have found that the ability of some corals to withstand higher water temperatures appears to be gene based. In their paper published in the Proceedings of the National Academy of Sciences, the group outline how they compared two types of corals commonly found in a reef in American Samoa, and found that those that are more heat resistant tend to express more gene types during normal temperature conditions.
