Figure 1. The transcriptional stability of five internal reference genes in infected and non-infected elm saplings.

Figure 1

(a–e) The expression of five reference genes encoding NAD (H) kinase 1, vacuolar ATP synthase, EIF 5a, ascorbate peroxidase and splicing factor 3B was investigated in saplings of ‘Valley Forge’ (VF) and the susceptible (S) elm clone at 0–144 hpi with the O. novo-ulmi fungus. The 72 hour sampling time point was missing due to uncontrollable circumstances. The expression of each gene was calculated relative to the control sample (0 hpi) in the susceptible clone.
