Ha18764 suppresses immune-associated cell death. (A) Ha18764 suppressed PsojNIP-triggered cell death. (B) Ha18764 suppressed the cell death triggered by either Avr3a/R3a or Gpa2/RBP-1. The empty pMD1 vector served as a negative control. (C) Ha18764 suppressed MAPK cascade-associated cell death. Nicotiana benthamiana leaves were infiltrated with buffer or Agrobacterium tumefaciens cells carrying Ha18764 or the negative control, either alone or 24 h prior to infiltration with A. tumefaciens cells carrying the elicitors. Photographs of infiltrated leaves were taken ca. 4 days after the last infiltration. Four circles marked with Roman numerals represented regions injected with different A. tumefaciens, which is indicated under the photographs. The numbers in parentheses indicate the proportion of infiltrated sites showing cell-death-suppressing symptoms. The original Western blotting images for the verification of gene expression were provided in Supplementary Figures S3, S4.
