From: Polyketide synthases of Diaporthe helianthi and involvement of DhPKS1 in virulence on sunflower
Pathogenicity bioassay of Diaporthe helianthi strain 7/96 (a) and ΔDhPKS1 mutant 7/96-Tr1 (b) on sunflower stem. c Development of necrotic area (cm2) on leaf blade in sunflower plants inoculated with the mutant (ΔDhPKS1), parental (wild type) and empty vector transformant strains. Observations made at 36, 72 and 84 h after inoculum. Different letters indicate statistically significant differences (p < 0.01) at T3 Dunnett test
