Two divergent haplogroups of a sacsin-like gene in Acropora corals

Abstract Reef-building corals are declining due to environmental changes. Sacsin is a member of the heat shock proteins and has been reported as a candidate protein associated with the stress response in Acropora corals. Recently, high nucleotide diversity and the persistence of two divergent haplog...
