The two pathogenesis-related genes (PR3 and PR10) were substantially expressed in all cultivars after the pathogen inoculation, with time- and cultivar-dependent expression profiles: early increased expression levels of PR3 in all cultivars followed by a decrease over the time-course of infection (expect in MHL-cultivar); a Gaussian-type expression profile for PR10 in both BTT (B) and SWT (S) cultivars, with BTT showing the highest expression levels of PR10 (at 3–5 d.p.i.)compared to other cultivars, which then decreased (Figure 8). The gene discussed is PRTN3; the disease is infection.
