Functional Crosstalk between Discrete Indole Terpenoid Gene Clusters in Tolypocladium album

Indole terpenoids make up a large group of secondary metabolites that display an enticing array of bioactivities. While indole diterpene (IDT) and rarely indole sesquiterpene (IST) pathways have been found individually in filamentous fungi, here we show that both cluster types are encoded within the genome of . Through heterologous reconstruction, we demonstrate the cluster encodes for IST biosynthesis and can tailor IDT substrates produced by the cluster.
