New Genus for the Globular Species of the Dinoflagellate Gambierdiscus (Dinophyceae)

Friday, November 13, 2015 3:20:43 PM East Boothbay, Maine

The dinoflagellate genus Gambierdiscus is a toxicologically important genus responsible for ciguatera fish poisoning, the principal cause of non-bacterial illness associated with fish consumption. The genus currently contains species exhibiting either globular or anterior-posteriorly compressed morphologies with marked differences in cell shape and plate arrangement. Fukuyoa, a genus of dinoflagellate that is found in similar habitats as Gambierdiscus, with a vague resemblance to Gambierdiscus, has recently been isolated from a sandy beach in Ubatuba, Brazil. It is a close relative to Gambierdiscus but differs not only in its morphology (plate pattern, shape is more lentil-like therefore just slightly laterally compressed) and DNA sequence (large and small subunit ribosomal DNA sequences), but in its toxicity in that it is not toxic (it was tested according to the procedure described by Xu et al. (Harmful Algae 2014; 34: 56–68). 

The NCMA is contiually adding to the public collection to create the most diverse collection possible by bringing in newly named genera and type strains. We are pleased to have been able to access CCMP3447 Fukuyoa paulensis, thanks to the authors of the paper describing this new species (see below).  It grows well at 24 degrees C in L1-Si medium made using our local seawater.
