N2  - HarpinPss, encoded by hrpZ in the hrp gene cluster from Pseudomonas syringae pv. syringae, is a glycine-rich, cysteine-lacking protein. It acts as an hypersensitive response (HR) elicitor in certain plants like tobacco, tomato and petunia. We isolated a 20 kDa protein, AP1, from tomato leaves, that could inhibit the activation of the HR by harpinPss. The interaction between AP1 and harpinPss resulted in an increase in the molecular weight of AP1.The inhibition of harpinPss elicitor activity or interference may be due to the competition between these two proteins for a putative receptor site in the plant cell plasma membrane. The C-terminal portion of harpinPss interacts more strongly with AP1 than the N-terminal portion.
