'Robust' coral produces amino acids to defend against bleaching

Science
Nov. 2 (UPI) -- Some coral reefs have a stronger genetic makeup to fight off bleaching, a recent study said. Researchers recently discovered that so-called "robust" coral, which includes certain brain corals and mushroom corals, are capable of producing special amino acids that prevent bleaching. Other coral, like "complex" coral, have a special relationship with microalgae called Symbiodinium, which helps them to build their hard skeletons. But these robust coral don't need them. "We now know that 'robust' corals can make at least one of the 'essential' amino acids without relying on Symbiodinium," David Miller, a professor at the ARC Center of Excellence for Coral Reef Studies, said in a press release. "This suggests that they may be more resilient, at least in the short term, to bleach...
