Comparison of mitogen‐activated protein kinase (MAPK) signalling between Magnaporthe oryzae MoMps1–MoSwi6 and Saccharomyces cerevisiae Slt2–Swi6. Schematic illustration of MoSwi6 functioning downstream of MoMps1 to regulate mycelial and conidial morphogenesis, cell wall integrity and virulence in M. oryzae. MoMps1 is thought to interact with MoSwi6, and MoMig1 may also function downstream of MoMps1 independent of MoMps1 (Jeon et al., 2008; Mehrabi et al., 2008) (indicated by the dotted outline). The MoMps1–MoSwi6 pathway mimics the Slt2–Swi6 pathway of S. cerevisiae (Iyer et al., 2001; Levin, 2005; Watanabe et al., 1995).
