Question:
Which of the following group of viruses generally infect plants?
Which of the following group of viruses generally infect plants?
Show Hint
• Most plant viruses → RNA viruses
• Example: TMV
Updated On: May 13, 2026
- Retroviruses
- Riboviruses
- Rheoviruses
- Enteroviruses
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Plant viruses are predominantly RNA viruses, often referred to as riboviruses.
• They have RNA as genetic material
• Examples include Tobacco mosaic virus (TMV)
Step 1: Analyzing each option.
• Retroviruses: Infect animals (e.g., HIV) → Incorrect.
• Riboviruses: RNA viruses commonly infect plants → Correct.
• Rheoviruses: Infect animals and plants, but not generally classified as main plant viruses → Less appropriate.
• Enteroviruses: Infect humans → Incorrect.
Step 2: Selecting the correct answer.
Thus, riboviruses generally infect plants.
• They have RNA as genetic material
• Examples include Tobacco mosaic virus (TMV)
Step 1: Analyzing each option.
• Retroviruses: Infect animals (e.g., HIV) → Incorrect.
• Riboviruses: RNA viruses commonly infect plants → Correct.
• Rheoviruses: Infect animals and plants, but not generally classified as main plant viruses → Less appropriate.
• Enteroviruses: Infect humans → Incorrect.
Step 2: Selecting the correct answer.
Thus, riboviruses generally infect plants.
