[Pathogenesis and induced virus resistance in tobacco plants affected by tomato spotted wilt virus].
Pathogenecity and virulence of tomato spotted wilt virus isolated from tobacco were studied under the field conditions of the Crimea in the tobacco plants of Immunny 580 variety and Datura stramonium. As to their virulence the obtained 26 isolates were divided into three groups: strongly virulent (severe), middle-virulent and weakly virulent ("mosaic"). It has been shown that strongly virulent isolates interfere with weakly virulent ones and induce the development of nonspecific resistance in tobacco plants, this resistance is also efficient to the tobacco mosaic virus.
