Spatial Uncoupling of Mitosis and Cytokinesis Is Associated with Appressorium Formation in the Rice Blast Fungus M. oryzae.
Schematic diagram to show the position and organization of septum formation in M. oryzae during appressorium development. The site of septation is spatially separated from the previous nuclear division. This contrasts with common patterns of septation in fungi, in which nuclear division is associated with the subsequent site of cytokinesis and septation. This occurs during spore germination in A. nidulans, budding of S. cerevisiae, and fission of S. pombe. Closed arrows indicate position of actomyosin ring formation; open arrows indicate direction of nuclear movement; nuclei are represented by closed circles.
