Expression patterna of the secondary metabolite biosynthetic gene clusters under four growth conditions.

a+++, >90% of the genes belonging to the cluster are expressed under the condition indicated. ++, 50–90% of the genes belonging to the cluster are expressed under the condition indicated. +, 25–50% of the genes belonging to the cluster are expressed under the condition indicated. −, 0–25% of the genes belonging to the cluster are expressed under the condition indicated.bDTC and STC indicate diterpene synthase and sesquiterpene synthase, respectively.Key enzymes of which the respective product is known are indicated in bold letters and the respective metabolites are listed; n/k indicates that the corresponding metabolite is not yet known. Red labeled key enzymes and corresponding metabolites are Fusarium fujikuroi-specific.
