Overview of the architecture of the pks1 gene cluster in T. atroviride P1 and comparison between selected 6-PP producing Trichoderma species. Cluster comparison based on sequence similarity and gene functional prediction. The polyketide synthase gene pks1 in T. atroviride P1 and orthologs in T. atroviride IMI206040, T. gamsii, and T. asperellum are colored in blue. Gene orthologs in the BGC are connected by black lines and color-coded according to their predicted gene function. Schematic domain organization of Pks1 is given on top. Pks1 harbors a ketosynthase (KS), acyltransferase (AT), dehydratase (DH), methyltransferase (MT), enoyl reductase (ER), and ketoreductase (KR) domain
