Outline of Final Research Achievements

Thraustochytrium is the type genus of the family Thraustochytriaceae in the class Labyrinthulomycetes. This genus is characterized by morphological features, however, there are several issues associated with the taxonomy of this genus, and these include polyphyletic taxa
and overlapping of taxonomic features among species. In this study, we make the attempt to find out the type spacies of this genus, but we could not isolate the strain of type species. On the other hand, we successfully isolated the strain, which exhibited characteristic features of second species of the genus Thraustochytrium, T. globosum. Based on comparison of the morphological characteristics of all the species in the genus Thraustochytrium and the molecular phylogenetic information, we propose the establishment of a new genus, Monorhizochytrium, for the species T. globosum in the family Thraustochytriaceae.
