Tobacco Mosaic Virus (TMV) readily infects a wide range of host plants which includes tobacco. Symptoms of infection vary depending on the host species, environmental conditions and the strain of TMV. Some strains, such as PV42, produce symptoms which are essentially masked. Other strains, for example PV230, induce severe yellow chlorosis in leaves. One explanation for the difference in symptom severity postulates that where virus accumulation is high symptoms are severe (1). However, other results suggest that it is a specific effect of the viral coat protein (vCP) which regulates the development and/or severity of disease symptoms (2,3).
