Research Abstract

A phytopathogen Alternaria and an entomopathogen Metarhizium produce the common toxin destruxin and infect plant and insect hosts, respectively. On the other hand, a phytopathogen Fusarium and an entomopathogen Beauveria produce the common toxin boubericin. Both toxins are cyclic peptides. To elucidate pathological roles of those common toxins produced by both phytopathogenic and entomopathogenic fungi, cloning and characterization of genes for the toxin biosynthesis in those pathogens have been tried in this study.
