Fungi offer a deep source of natural products but remain underutilized. Most biosynthetic gene clusters (BGCs) that can be detected are silent or “cryptic” in standard lab cultures and their products are thus not interrogated in routine screens. As genetic alterations are difficult and some strains can only be grown on agar, we have herein applied an agar-based high-throughput chem. genetic screen to identify inducers of fungal BGCs. Using R. solani and S. sclerotiorum as test cases, we report 13 cryptic metabolites in four compound groups, including sclerocyclane, a natural product with a novel scaffold. Steroids were the best elicitors and follow-up studies showed that plant-steroids trigger sclerocyclane synthesis, which shows antibiotic activity against B. plantarii, an ecol. competitor of S. sclerotiorum. Our results open new paths to exploring the chem. ecol. of fungal-plant interactions and provide a genetics-free approach for uncovering cryptic fungal metabolites.
