RBP2 and infection: Upon R. solanacearum inoculation, the areas overexpressing RBP.1, ER68.1, SNR.1, and U2AF65C.1 in N. benthamiana leaves showed inhibited R. solanacearum CQPS-1 infection compared to the GFP control, while the overexpression of RBP.2, ER68.2, SNR.2, and U2AF65C.2 had no significant effect (Figure 4A and Figure S2).
