Knock-down of the methyltransferase Kmt6 reliefs H3K27me3 and induces expression of cryptic otherwise silent secondary metabolite gene clusters in Fusarium fujikuroi [gene expression]

ABSTRACT: Filamentous fungi produce a vast array of secondary metabolites (SMs) and some of them are applied in agriculture or pharmacology. Recent sequencing of the rice pathogen Fusarium fujikuroi revealed the presence of far more SM-encoding genes than known products. SM production is energy-consuming and thus tightly regulated, leaving the majority of SM gene clusters silent under laboratory conditions. It is now well established that one important regulatory layer in SM biosynthesis involves histone modifications that render the genes either silent or poised for transcription. In this study, we show that the majority of the putative SM gene clusters in F. fujikuroi are located within facultative heterochromatin marked by H3K27me3. In this study, we performed comparative transcriptomics of a kno
