We found that the protein synthesis inhibitor hygromycin B induced the production of secondary metabolites, including lucilactaene, NG-391, fusarubin, 1233A, and 1233B, in the filamentous fungus, Fusarium sp. RK97-94. We identified the biosynthetic gene cluster for 1233A, an HMG-CoA synthase inhibitor. The biosynthetic gene cluster consisted of four genes, one of which was involved in conferring self-resistance to 1233A.
