To elucidate the regulatory dynamics of the Pb-PR-1 gene family in response to fire blight infection, we conducted an analysis of the expression profiles of PR-1 genes in both resistant and susceptible Duli at 2, 4, and 6 days post-infection (dpi) utilizing RT-qPCR, with non-infected controls (Sck) serving as a reference (Figure 9 and Figure S1). The gene discussed is TMEM37; the disease is infection.
