Figure 7: Putative U. virens effectors suppressed B. glumae-induced HR in N. benthamiana.

Representative cell death symptoms were photographed at 2–3 days after B. glumae inoculation. The left half leaf sections were injected with B. glumae with the pEDV empty vector and the right half sections were injected with B. glumae with effector gene constructs. Numbers, for instance 27/36, indicate that the 27 right leaf sections out of 36 inoculated leaves showed no or significantly less severe symptoms as compared with left sections.
