Homoserine treatment reduces F. culmorum growth in point inoculated eds1- 2 siliques. Tip-wounded eds1-2 siliques were treated with 10 mM L-homoserine (LHS), D-homoserine (DHS) or sterile water coincident with F. culmorum inoculation. Amino acid/water treatment was repeated for 5 dpi. Images show infected siliques 8 dpi under bright field (BF) and UV light with a violet filter. Red fluorescence indicates healthy tissue, green fluorescence indicates infected tissue. The length of infection (mm) along three siliques per plant was assessed at 8 dpi. Different letters indicate statistically significant differences between treatments (analysis of variance followed by prediction of LSDs, p = <0.01, n = 12). Data were pooled from three independent experiments.
