A new Symbiodinium clade (Dinophyceae) from soritid foraminifera in Hawai’i
Molecular Phylogenetics and Evolution
Dinoflagellates in the genus Symbiodinium are crucial components of coral reef ecosystems in their roles as endosymbionts of corals and other marine invertebrates. The genus Symbiodinium encompasses eight lineages (clades A–H), and multiple sub-clade types. Symbiodinium in clades A, B, C, and D are most commonly associated with metazoan hosts while clades C, D, F, G, and H with large soritid foraminifera. Recent studies have described a diversity of new Symbiodinium types within each clades, but no new clades have been reported since 2001. Here, we describe a new clade of Symbiodinium isolated from soritid foraminifera from Hawai’i.
