Abstract

Fusarium graminearum is a destructive phytopathogen and shows an impressive metabolic diversity. Gene deletion is an important and useful approach for gene function study. Here we present a protocol for generating gene deletion mutant by applying “split-marker” deletion strategy (Catlett et al., 2003) with PEG-mediated protoplast transformation (Yuan et al., 2008; Martín, 2015).
