Miracula blauvikensis: a new species of Miracula from Iceland, and report of a co-cultivation system for studying oomycete-diatom interactions.

ABSTRACT: The genus Miracula represents an early-diverging lineage of diatom-parasitic Oomycota, straminipilous eukaryotes that have evolved fungal features independent from the opisthokont Fungi. Recent studies have revealed that diatom parasitoids are much more species-rich than previously thought and may play an important role in limnic and marine ecosystems. Of the different diatom-parasitic lineages, the genus Miracula is one of the most abundant in marine ecosystems. Here a species of Miracula parasitising Fragilaria capucina s.l. from Iceland is described as Miracula blauvikensis. In addition, its phylogenetic position is clarified and its life-cycle documented. The species has been brought into co-cultivation with its host, and due to the ease of cultivation and the convenient microscopy of the diatom threads, this co-culture might be a useful tool to study oomycete-diatom interactions in the future.
