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.

Miracula blauvikensis:一种新的Miracula从冰岛,并报告co-cultivation系统为研究oomycete-diatom交互。

Miracula属代表了一个早期分化的硅藻寄生卵菌科谱系，这是一种具有独立于opisthokont真菌的真菌特征的链状真核生物。最近的研究表明，硅藻类寄生物的种类比以前认为的要丰富得多，并且可能在湖泊和海洋生态系统中发挥重要作用。在不同的硅藻寄生谱系中，奇迹藻属是海洋生态系统中最丰富的一种。本文描述了一种寄生于冰岛花椒的奇迹般蝇，称为blauvikensis。此外，还阐明了其系统发育位置，并记录了其生命周期。该物种已与寄主共培养，由于易于培养和硅藻线的显微镜观察，这种共培养可能是未来研究卵菌-硅藻相互作用的有用工具。引用本文:Buaya A, Thines M(2022)。Miracula blauvikensis:一种新的Miracula从冰岛,并报告co-cultivation系统为研究oomycete-diatom交互。真菌分类学与进化(10):169-175。doi: 10.3114 / fuse.2022.10.07。
