The strains with strong virulence defects (SG200 cda2,3,4,5,6em and SG200 cda2,3,4,5,6emΔ7) showed significant reductions in fungal biomass already at 2 dpi, while SG200 cda1,3,4,5,6emΔ7 was reduced in biomass starting at 6 dpi; in infections with SG200 Δcda7, biomass reduction became apparent only after 8 dpi (Fig. S7H). The gene discussed is AICDA; the disease is infection.
