Figure 1.

Time-lapse confocal fluorescence images and schematic diagram of intermediate mitosis in an invasive hypha of M. oryzae within the first-invaded rice cell. This strain expresses histone H1-tdTomato and GFP-NLS. The top panel shows five sequential fluorescence pattern stages in both merged bright-field and fluorescence (top), red fluorescence alone (middle), and green fluorescence alone (bottom). The interphase nucleus in G2 appears yellow due to colocalization of H1-tdTomato (red) and GFP-NLS (green) within the nucleus. H1-tdTomato remains associated with DNA throughout the cell cycle. During the early stages of mitosis (M), GFP-NLS spills into the cytoplasm, indicating a change to the integrity of the nuclear envelope. GFP-NLS is contained within the dividing cell by presumed closure of septal pores. Following mitosis, GFP-NLS is reimported back into the nucleus and the nucleus again becomes yellow during interphase (G1). The bottom panel presents a schematic summary of these cellular events.
