What is the host range of the Tobacco/Tomato mosaic tobamovirus?

The host range of the Tobacco/Tomato mosaic tobamovirus prominently includes plants such as tobacco, tomato, and various ornamental species. This virus is well-known for infecting members of the Solanaceae family, which consists of both the tobacco and tomato plants. Additionally, it can infect several ornamental plants, making option B the correct choice. Understanding the host range of this virus is essential for effective disease management and control strategies in crops where this pathogen could pose a threat.

The other options include plants that are not susceptible to this particular virus, highlighting the specificity of tobamoviruses in relation to their preferred hosts. For instance, cucumbers, peppers, zucchini, wheat, barley, rye, carrots, lettuce, and radishes fall under different plant families or communities and do not support the same viral infections associated with the Tobacco/Tomato mosaic tobamovirus.
