INTEREST OF MY RESEARCH

Filamentous fungi (molds) are well known as plant and animal pathogens and mycotoxin producers. On the other hand, filamentous fungi are useful in production of fermentation foods (sake etc.) and medicines. Recently, it has become apparent that huge numbers of secondary metabolism genes of unknown functions are sleeping in the genomes of filamentous fungi. Aims of my research are to develop medicines by using these genes and to develop agrochemicals that control production of fungal secondary metabolites required for pathogenicity.
