FIG. 7.

Inhibition of programmed cell death by AvrPtoB in AvrPtoB homologs in N. benthamiana leaves. (A) The following proteins were coexpressed with AvrPto and Pto in mature leaves of N. benthamiana using Agrobacterium-mediated transient expression: none (empty vector) (leaf 1), AvrPtoB (leaf 2), AvrPtoB_T1 (leaf 3), AvrPtoB_PT23 (leaf 4), AvrPtoB_B728a (leaf 5), and HopPmaL (leaf 6). Photographs were taken 7 days after Agrobacterium infiltration. (B) Ion leakage in the area infiltrated with A. tumefaciens expressing AvrPto, Pto, AvrPtoB, or AvrPtoB homologs 1, 3, 5, and 7 days after infiltration. Conductivity is indicated on the y axis.
