RESUMO
Fusarium oxysporum is a cross-kingdom fungal pathogen that not only causes devastating plant vascular diseases but can also opportunistically infect humans. Here we describe two high-throughput screening assays, a resazurin cell viability assay and an optical density assay, to screen natural products from cultured plant cells with antifungal properties against a clinical isolate of F. oxysporum. After elicitation by applying methyl jasmonate or by co-culture with F. oxysporum, as an abiotic elicitor and a biotic elicitor, respectively, we identified three cell lines that produce materials that inhibit fungal growth. Our procedure validates the powerful potential of combining high-throughput methods for the discovery of novel anti-pathogenic leads.
