CC -!- FUNCTION: Mitogen-activated protein kinase; part of the MST11-MST7-PMK1
CC MAP kinase (MAPK) cascade that is essential for appressorium formation,
CC penetration and invasive growth (PubMed:8946911, PubMed:11952120,
CC PubMed:15749760, PubMed:21283781, PubMed:23085322, PubMed:23454094,
CC PubMed:27059015). Central regulator of appressorium development that
CC acts downstream of the cAMP signal (PubMed:8946911, PubMed:23591122).
CC The MST11-MST7-PMK1 MAP kinase cascade transduces signals from the cell
CC surface sensors MDB2 and SHO1 that recognize various surface signals
CC such as surface hydrophobicity, cutin monomers, and rice leaf waxes
CC (PubMed:21283781). Regulates expression of secreted fungal effector
CC proteins implicated of host immune defenses, preventing reactive oxygen
CC species generation and excessive callose deposition at plasmodesmata
CC (PubMed:29567712). Furthermore, controls the hyphal constriction
CC required for fungal growth from one rice cell to the neighboring cell,
CC enabling host tissue colonization and blast disease (PubMed:29567712).
CC Targets downstream of the PMK1-MAPK pathway include transcription
CC factor MST12 and pathogenicity-related genes GAS1 and GAS2, both of
CC which are expressed during appressorium formation, even if regulation
CC of MST12 is not associated with expression of GAS1 or GAS2
CC (PubMed:12215509, PubMed:11952120, PubMed:23454094).

CC -!- DISRUPTION PHENOTYPE: Impairs the formation of appressoria and the
CC ability to infect rice plants, even when inoculated onto wounded leaves
CC (PubMed:8946911, PubMed:23591122, PubMed:23454094). Leads to decreased
CC transcription of the cell surface sensors MSB2 and SHO1
CC (PubMed:21283781). Blocks the transcription of both virulence genes
CC GAS1 and GAS2 during appressorium formation (PubMed:12215509).
