Analysis of susceptibility to F. graminearum infection in plants harbouring different alleles of the dmr1 mutation, dmr1- 1 and dmr1- 2, compared to the parental line eds1- 2 . Panel (a) shows infection of the apical inflorescence and siliques in eds1-2 and dmr1-2 at 7, 11, and 14 dpi. In panel (b) the rosette leaves of the dmr1 alleles are compared to eds1-2, and the stem and floral tissues have been removed. Bar =1 cm. Eight plants per genotype were scored for (c) floral disease levels, (d) silique disease levels, (e) number of green, uninfected siliques and (f) number of infected rosette leaves and at 7, 11 and 14 dpi. Asterisks indicate genotypes significantly different from eds1-2 at each time point (regression analysis followed by calculation of LSDs, p = <0.05). Error bars represent standard error of the mean. The experiment was repeated with similar results.
