Cover Story: The discovery of Cafileria marina expands the number of known taxa from the non-photosynthetic stramenopiles, once again demonstrating the species richness of heterotrophic nanoflagellates. C. marina is a new species of a new genus with a unique ultrastructural phenomenon observed in young cells, a close connection of the mitochondria with the nucleus. The cover image shows a transmission electron microscopy picture of this cell structure, as well as a confocal fluorescence image. The remaining two illustrations are a 3D reconstruction of the connection based on Z-stack pictures and a model of the flagellar apparatus. View this paper.
