Bacterial growth upon Pst infection of NP-exposed and non-exposed plants. Mayor rossete leaves of plants were inoculated with a suspension containing 10⁴ colony forming units (cfu) of the Pst strain or with a mock solution (control) 24 h after exposure to NPs.cfu were counted in inoculated and distal leaves 2 days after inoculation. The effect of supplementation with SA 12 h before NP addition was measured in another series of plants. Bacterial growth in distal leaves of NP-treated plants was significantly increased respect to the control plants.
