"Tobacco mosaic virus (TMV) and Tomato mosaic virus (ToMV) are two closely related viruses in the genus Tobamovirus, but they induce obviously different sizes of necrotic lesions in tobacco plants containing the N gene."
Yu, C., Hu, D., Dong, J. et al. The symptom difference induced by Tobacco mosaic virus and Tomato mosaic virus in tobacco plants containing the N gene is determined by movement protein gene. Sci. China Ser. C.-Life Sci. 47, 503–509 (2004). https://doi.org/10.1360/03yc0156
Tobacco mosaic virus (TMV) and Tomato mosaic virus (ToMV) infect several solanaceous species. Both viruses produce local lesions on Nicotiana glutinosa and Nicotiana tabacum cv. Xanthi. The two viruses could be differentiated based on the symptoms on Nicotiana sylvestris and N. tabacum cv. White Burley: TMV produces systemic infection in both these hosts, whereas ToMV produces only local lesions.
