The Late Endosomal HOPS Complex Anchors Active G-Protein Signaling Essential for Pathogenesis in Magnaporthe oryzae
Figure 5
Rgs1 utilizes microtubules to traverse along the germ tube.
Destabilization of the microtubule cytoskeleton disrupts Rgs1 dynamics. MBC treatment leads to Rgs1-mC (pseudocolored yellow) accumulation along the plasma membrane in the developing appressorium (asterisk) and cytoplasmic aggregation or clustering (arrowhead). The region of the germ tube lacking the Rgs1-mC tubulo-vesicular structures is bracketed. DMSO-treated sample served as a negative control. Elapsed time (in seconds) is recorded in panels D and E. Scale bar, 10 µm.
