Abstract
Light plays an important role in the induction of resistance responses in various plants against diseases. In this study, the inhibition was investigated of wildfire disease caused by Pseudomonas syringae pv. tabaci in Nicotiana benthamiana in response to irradiation with light emitting diodes (LEDs) To identify the effects of various wavelengths on the induction of defense responses, N. benthamiana plants were irradiated for three days with various LEDs (380, 440, 470, and 660 nm) before and after inoculation. Symptom development showed greater suppression in response to irradiation with blue (440 nm) and red (660 nm) light than fluorescent lights. Additionally, fewer bacterial cells were recovered from the lesions of LED-treated leaves than those of fluorescent light-treated leaves. Simple LED irradiation induced the expression of defense-related genes including catalase (CAT), chalcone synthase (CHS), gluthatione-S-transferase (GST), pathogenesis-related protein (PR Q), proteinase inhibitor II (PinII), and thaumatin-like protein (TLP). Taken together, these data suggest that irradiation by LEDs could inhibit wildfire development by inducing defense responses in N. benthamiana plants.
