Infection-related development in the rice blast fungus Magnaporthe grisea

Curr Opin Microbiol. 1998 Dec;1(6):693-7. doi: 10.1016/s1369-5274(98)80117-3.


Recent developments have been made in the identification of signal transduction pathways and gene products involved in the infection-related development of the rice blast fungus, Magnaporthe grisea. It has been established that cAMP-dependent and MAP kinase-mediated signaling are both critical for appressorium morphogenesis and function. These signaling pathways may act downstream of hydrophobin-mediated surface sensing by the growing germ tube. Several genes have been identified that are required for invasive growth of M. grisea including genes that allow adaptation of fungal metabolism to growth within plant tissues.
