In plant virology, Tobacco mosaic virus (TMV) is classically associated with causing mosaic disease in which plant host?

• A. Tobacco (Nicotiana tabacum)
• B. Apple (Malus domestica)
• C. Wheat (Triticum aestivum)
• D. Potato (Solanum tuberosum)

Answer: (A)

Verified step by step guidance

1. Understand that Tobacco mosaic virus (TMV) is a well-studied plant virus known for infecting specific host plants.
2. Recall that TMV primarily infects plants in the Solanaceae family, which includes tobacco, tomato, and related species.
3. Identify the plant hosts listed in the problem: Tobacco (Nicotiana tabacum), Apple (Malus domestica), Wheat (Triticum aestivum), and Potato (Solanum tuberosum).
4. Recognize that TMV is classically associated with causing mosaic disease specifically in Tobacco (Nicotiana tabacum), which is its most common and historically significant host.
5. Conclude that among the options, Tobacco (Nicotiana tabacum) is the correct host plant for TMV-induced mosaic disease.
