Detailed explanation-1: -Tobacco mosaic virus (TMV) is a plant virus that belongs to the genus Tobamovirus. It is named so because it majorly infects tobacco plants, potatoes, tomatoes and other members of the Solanaceae family. The infection creates a mosaic like pattern, mottling and discoloration of the leaves.

Detailed explanation-2: -Pathogen Biology Hosts for TMV include tobacco (Figure 1), tomato (Figure 5), and other solanaceous plants. Currently, yield losses for tobacco due to TMV are estimated at only 1% because resistant varieties are routinely grown. In contrast, losses of up to 20% have been reported for tomato.

Detailed explanation-3: -Tobacco mosaic virus (TMV) has a 6.3-kb positive-stranded RNA genome which encodes four proteins (reviewed in references 1, 2, and 6). The 126-and 183-kDa proteins have essential replication functions and are translated from the virus genomic RNA.
