O’Connell4, Ken Shirasu1,5* Many plant pathogenic fungi penetrate host surfaces mechanically, using turgor pressure generated by specialized infection cells called appressoria. These appressoria develop semipermeable cell walls and accumulate osmolytes internally to create turgor by osmosis. Although melanin is known to be important for turgor generation, the mechanism underlying wall semipermeability remains unclear. By using reverse genetics, we identified that the enzymes PKS2 and PBG13 are required for forming the semipermeable barrier in fungi causing anthracnose and rice blast diseases. …
