Acetylsalicylic acid (aspirin) induces resistance to tobacco mosaic virus in tobacco

Tobacco cv. Xanthi-nc becomes resistant to tobacco mosaic virus (TMV) and produces b proteins when injected with the interferon inducer polyacrylic acid. Injection of acetylsalicylic acid (aspirin), benzoic acid, or salicylic acid also induces this response in Xanthi-nc. Injection of aspirin, benzoic acid, or salicylic acid similarly induces resistance and the formation of new proteins in the White Burley and Samsun NN cultivars of tobacco.
