The tomato strain of TMV dealt with herein is chracterized by its producing local lesions but no systemic infection on certain varieties of N. tabacum (Bright Yellow etc.), and also by its higher affinity to tomato plant as compared with the TMV ordinary strain. When the tomato strain and the ordinary strain of TMV were inoculated to seven principal tobacco varieties cultivated in Japan, the tomato strain produced only local lesions on all the varieties, while the ordinary strain produced only systemic mosaic symptoms.<BR>In a survey to see to what extent cigarettes may carry TMV, all of the sixteen Japanese brands (320 lots) tested were found to contain TMV. Strains of the TMV isolates were tested on several test plants. All isolates from eleven brands were only the ordinary strain, while both ordinary and tomato strains were isolated from five of the brands…Hilite, Hope, Kohaku, Izumi and MF.<BR>The tomato strain of TMV is found at a high rate in tomato plants in the field, but is contained in a low percentage in cigarettes manufactured in Japan. This suggests that cigarettes may not be an important source of TMV for tomato crops in Japan.
