| Research Abstract |
A full-length clone of putative polyketide synthase responsible for unknown mycotoxin biosynthesis was isolated from Fusarium graminearum, one of the rice adherent fungi. This clone was served for a heterologous expression in a transformed Aspergillus oryzae, which suggested this clone to be a novel polyketide synthase. Also, in vitro cultures of various Fusarium fungi followed by chromatographic analysis revealed the production of fumonisins by the fungus that had not been reported as a fumonisin-producer.
