To establish an infection, fungal pathogens must recog- nize diverse signals from host surfaces. The rice blast fungus, Magnaporthe oryzae, is one of the best models studying host-pathogen interactions. This fungus recog- nizes physical or chemical signals from the host surfac- es and initiates the development of an infection struc- ture called appressorium. Here, we found that protein MoAfo1(appressorium formation, MGG_10422) was involved in sensing signal molecules such as cutin mono- mers and... -
