Infected and Protected Grapevines

Caption

Expression of a hybrid protein blocks Pierce's disease in a grapevine. The hybrid protein (shown at the bottom right) creates pores in the membrane of the Gram-negative bacterium, Xf, that causes PD. The transgenic grapevine expressing the hybrid protein shows little or no leaf scorching as PD symptom upon Xf infection (top left) whereas the non-transgenic without the hybrid protein shows severe leaf scorching (top right).
