Constitutive and inducible expression of defense genes. The expression of the 21 genes (Additional File 4) was measured before and after inoculation with the M. oryzae isolate CD203 and compared to partial resistance index (A) as measured in Figure 1. A gene expression index (B), integrating all 21 gene expression values for each condition, was calculated as indicated in Additional file 5. Partial resistance and gene expression indexes correlate before infection (0 dpi) but not after (1 to 4 dpi)
