From: Bark and wood tissues of American elm exhibit distinct responses to Dutch elm disease
Expression of disease-responsive genes in the inoculated core tissues of ‘Valley Forge’ and ‘Princeton’. (a–l) Expression of different classes of disease responsive genes was investigated in the mock-inoculated (0 hpi) and inoculated core tissues of ‘Valley Forge’ (VF) and ‘Princeton’ (P). The expression of each gene was normalized to that of three elm reference genes (EIF 5a, vacuolar ATP synthase and splicing factor 3B) and was calculated relative to the control sample (P-bark at 0 hpi). The results are the mean ± SE of three biological replicates. Values marked with an asterisk (*) are significantly greater (≥2 times) than the control sample and the corresponding time point in the other genotype (P < 0.05).
