R protein induced systemic resistance in plants. Ross first proposed the system of plant acquired resistance, this resistance in re-infection, not only on the initial infection with the bacteria showed the same resistance, and often other types of bacteria also play a role. For example, TMV infection of tobacco induced systemic resistance,[link widoczny dla zalogowanych], not only the role of TMV itself, but also for other unrelated pathogens, such as necrotic lesions on tobacco virus (TNV) has resistance. In this study the total protein in each treatment were significantly increased after inoculation, also confirms the above point of view. CHINA AGRICULTURAL UNIVERSITY 21 At present, the plant induced disease in the ascendant, and its principle of disease prevention is mainly induced by the resistance of plants of the underlying function,[link widoczny dla zalogowanych], namely, plant by inducing changes in some metabolic pathways,[link widoczny dla zalogowanych], synthesis of phenolic or synthetic anti-viral plant factors and other antimicrobial substances,[link widoczny dla zalogowanych], and histologic changes, to prevent infection by the pathogen or inhibiting the bacteria expansion purposes. This method can effectively prevent disease and will not cause environmental pollution, help maintain balance of the ecosystem, has important theoretical value and a wide range of practical significance.
