Nup84 persists within the nuclear envelope of the rice blast fungus, Magnaporthe oryzae, during mitosis

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.

Figure 1: Arrangement of two nuclear envelope components in M. oryzae. (A) Maximum intensity projection of an SR-SIM image of M. oryzae strain CKF3810. A conidium of CKF3810 shows three nuclei in interphase. Nup84-tdTomato (left panel, red) localizes within the nuclear envelope. Nuclear contents are labelled with two constructs, histone H1 (hH1)-EGFP and EGFP-NLS (middle panel, green). Right panel is a merged image. Scale bar = 2 µm. (B) Single z-slice SR-SIM image of CKF3810 nucleus in the early stage of mitosis in the apical cell of the conidium. Nup84-tdTomato (left panel, red) surrounds hH1-EGFP (middle panel, green). A single z-slice image is displayed because it shows hH1-EGFP signal in optimal detail. EGFP-NLS is dispersed from the nucleus (data not shown). Right panel is a merged image. Scale bar = 1 µm. (C) Single z-slice SR-SIM image of CKF3881 nucleus in the apical cell of the conidium in interphase. Nup84-tdTomato (left panel, red) is distributed along the circumference of Src1-EGFP (middle panel, pseudocolored cyan). Right panel is a merged image. Scale bar = 1 µm.
