By considering the importance of TOR signaling to both pre- and post-penetration infection stages, the motivation for this study was to identify and characterize additional TOR pathway components in M. oryzae. Using forward and reverse genetics, pharmacological treatments and confocal microscopy, we discovered and characterized IMP1 encoding a vacuolar-localized protein that is required for vacuole function and membrane trafficking and also outlines IH during growth in planta. This evidence concerns the gene RORC and infection.
