Question:
Which of the following is fungi transmitted plant virus?
Which of the following is fungi transmitted plant virus?
Show Hint
Fungal-transmitted plant viruses: Bymovirus, Furovirus (transmitted by Polymyxa); Nepovirus is nematode-transmitted.
Updated On: Sep 15, 2026
- Rymovirus
- Nepovirus
- Trichovirus
- Bymovirus
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Plant viruses utilize biological vectors such as insects, nematodes, mites, and root-infecting plasmodiophorid protists/fungi for transmission.
Step 2: Detailed Explanation:
Viruses of the genus Bymovirus (family Potyviridae, e.g., Barley yellow mosaic virus) are obligately transmitted in soil by the root-endoparasitic plasmodiophorid fungus-like vector Polymyxa graminis.
Rymoviruses are transmitted by eriophyid mites, and Nepoviruses are transmitted by dorylaimid nematodes (Xiphinema).
Step 3: Final Answer:
Therefore, Bymovirus is the fungi-transmitted plant virus.
