| Outline of Final Research Achievements |
The causal agent of southern corn leaf blight, Bipolaris maydis develops infection structures called appressoria on plant leaves and polystyrene surface. In this study, we analyzed roles of SHO1, MSB2 and OPY2 in appressorial development of B. maydis. The disruptants of these genes are defective in formation of appressoria on polystyre surface, but not on plant leaves, suggestion that these genes are involved in physical surface sensing for appressorial formation. Moreover, we elucidated that B. maydis develops appressoria in response to plant pectin but not to cutin and hydroxy fatty acid on leaves.
