Molecular Systematics of Symbiodinium
The advent of DNA sequence comparison initiated a rebirth in the ordering and naming of all organisms. The application of this methodology helped overturn the long held belief that Symbiodinium comprised a single species, a process which began in earnest with the morphological, physiological, and biochemical comparisons of cultured isolates. Currently, genetic markers are exclusively used to describe ecological patterns and deduce evolutionary relationships among morphologically cryptic members of this group. Foremost in the molecular systematics of Symbiodinium is to resolve ecologically relevant units of diversity (i.e. species).
