Additionally, the statistically significant lower values of the disease progression curve for all three genetically modified lines (Rpi-amr3_5C, Rpi-amr1D_15A, and Rpi-amr1D_15B) compared to control Maris Piper showed that these transgenic lines can effectively control the infection of late blight in the field (Figure 2b). Here, RPIA is linked to infection.
