Virulence analysis of the two strains of F. verticillioides (WT and ΔFvlds1D mutant). Visual appearance of cobs artificially wounded, non-inoculated (mock) and inoculated with the two strains of F. verticillioides (WT and ΔFvlds1D) (A) 2 and (B) 7 DAI at 25°C in bottles containing Hoagland's solution. (C) Severity of F. verticillioides ear attack evaluated by a visual rating scale based on the SCIA (wounding and non-wounding) method (Marin et al., 2010). (D) Abundance of fungal DNA in maize ears at different DAI, as a measure of tissue colonization. This method adopts 7 classes based on the percentage of visibly infected kernels (Disease Severity Rating: 1 = 0%-no infection; 2 = 1–3%; 3 = 4–10%; 4 = 11–25%; 5 = 26–50%, 6 = 51–75%; 7 = 76–100%).
