Gene expression during early infection of the susceptible spring wheat cultivar Roblin with Fusarium graminearum, the major causal agent of fusarium head blight in wheat

Fusarium head blight (FHB) is a major disease of cereal crops caused by the fungus Fusarium graminearum (Fg). FHB affects the flowering heads (or spikes). This study compare the gene expression profile in wheat spikelets from the very susceptible spring wheat cultivar Roblin inoculated with water (H2O) or Fg. We used the Affymetrix wheat array to compare wheat spikelets from the very susceptible spring wheat cultivar Roblin inoculated with water (H) or Fg, using the point inoculation method; samplings were done at 1, 2 and 4 days (d) after inoculation, for 2 biological replicates
