Abstract
The arrangement of the nuclear envelope in the rice blast fungus, Magnaporthe oryzae, was previously undetermined. Here, we identified two conserved components of the nuclear envelope, a core nucleoporin, Nup84, and an inner nuclear membrane protein, Src1. Live-cell super-resolution structured illumination microscopy revealed that Nup84-tdTomato and Src1-EGFP colocalized within the nuclear envelope during interphase and that Nup84-tdTomato remained associated with the dividing nucleus. We also found that appressorium development involved a mitotic nuclear migration event through the germ tube.
