| Outline of Final Research Achievements |
Rice blast disease caused by the ascomycete fungus Magnaporthe oryzae is a serious and widespread disease of rice. The general fungicides inhibit either intracellular biosynthesis or metabolic pathway, would pose a high risk for development of fungicide resistance. Here, we have overexpressed and investigated two cellobiose dehydrogenase (CDH) homologues in M. oryzae to development a method to inhibit secreted proteins involved in the extracellular metabolic pathway for control of the fungal rice pathogen. Plant disease fungi produce and secrete hydrolases as well as oxidoreductases such as CDH to degrade the plant cell wall and to utilize cellulose as the nutrient carbon.
BLAST search using the M. oryzae genome database uncovered the existence of two CDH homologous gene, MGG_13809 (MoCDH1) and MGG_11036 (MoCDH2). The two CDH homologues were expressed in the methylotrophic yeast Pichia pastoris. MoCDH2 shows higher cellobiose dehydrogenase activity than MoCDH1.
