Evaluation of tobacco mosaic virus
Tobacco plants epigenetically suppressed in phenylalanine ammonia-lyase expression do not develop systemic acquired resistance in response to infection by tobacco mosaic virus
Resistance created by the introduction of replicase gene was first demonstrated for the tobacco mosaic virus
(TMV) in Nicotiana tabacum .
Abbreviations: DAI, days after inoculation; ELISA, enzyme-linked immunosorbent assay; SMV, Soybean mosaic virus; STN, stem-tip necrosis; TMV, Tobacco mosaic virus
; TSWV, Tomato spotted wilt tospovirus.
For example, tomato plant cultivars have various disease resistance to diseases such as verticillium wilt (V), fusarium wilt (F), fusarium races 1 & 2 (FF), nematodes (N), tobacco mosaic virus
(T), alternaria stem canker (A), and stemphylium gray leaf spot (St).
Stanley had succeeded in crystallizing tobacco mosaic virus
and proving that it was protein in nature (see 1935).
Louis and his colleagues demonstrated in 1986 that tobacco plants containing the gene that directs the production of the outer, or coat, protein of the tobacco mosaic virus
can resist later infection by the virus.
To prevent tobacco mosaic virus
, don't smoke around plants and wash hands thoroughly before handling them.
The letters represent: verticillium wilt resistance (fungal disease), fusarium wilt resistance (fungal disease), nematode resistance (insect), tobacco mosaic virus
resistance (viral disease) and alternaria disease resistance, also known as early blight (fungal disease).
If you produce your own plants from seed of resistant varieties or purchase plants from a local grower who sells only plants produced locally, you will avoid not only late blight but also fusarium and verticillium wilt fungus, tobacco mosaic virus
, root knot nematode and other challenges.
The antiviral effect of tea tree oil against tobacco mosaic virus
, a nonenveloped plant virus, has been reported previously (Bishop, 1995).
The F2 generation of an equally represented composite of three crosses between wilt-susceptible Connecticut broadleaf tobacco lines and the tobacco mosaic virus
(TMV)-resistant, wilt-resistant cultivar C2 (C2 x `Winn'; C2 x `Gogulski'; and C2 x `Gradowski') was selected for resistance under greenhouse and field conditions.
