RT-qPCR results for 6 selected differentially expressed genes illustrating three main types of expression patterns indicative of: a induced defence, b induced and constitutive defence, c constitutive defence. All displayed genes belong to the MAPK signalling and plant hormone signal transduction pathways (for the whole set of 30 genes explored by RT-qPCR see Additional file 18: Figure S8). Relative expression changes (mean fold change ± SE, n = 3) were calculated for resistant (R) vs. susceptible genotypes (A, B, D) and symptomatic (S) vs. non-symptomatic (NS) needles at 7, 18, 29, and 38 dpi. * p < 0.05 (Welch’s t-test). N/A: fold changes could not be calculated as the respective transcript was not detected in one of the comparison partners; n.d.: transcript was not detected in both comparison partners
