A. They only transfer virulent factors to host
B. Plant attracts the virulence factors by its chemical signals
C. This kind of pathogen survive in the rhizosphere of the infected plant
D. Virulence factors can be cultured on media
E. Infected plant can be recovered with time

Show Hint
Pathogens not at symptom site:
- Agrobacterium survives in rhizosphere.
- Plants release chemical signals.
- Recovery from infection is possible.
- Agrobacterium survives in rhizosphere.
- Plants release chemical signals.
- Recovery from infection is possible.

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of pathogens that do not live at the symptom site (e.g., Agrobacterium, some viruses).
Step 2: Detailed Explanation:
A. They only transfer virulent factors to host: Incorrect.
They transfer genetic material (T-DNA) or virulence factors to the host.
B. Plant attracts the virulence factors by its chemical signals: Correct.
Plants release signals that attract pathogens or virulence factors.
C. This kind of pathogen survive in the rhizosphere of the infected plant: Correct.
Some pathogens (e.g., Agrobacterium) survive in the soil/rhizosphere.
D. Virulence factors can be cultured on media: Incorrect.
Virulence factors are not cultured (they are genetic or chemical).
E. Infected plant can be recovered with time: Correct.
Some plants can recover from infection (e.g., crown gall recovery).
Thus, B, C, and E are correct.
Step 3: Final Answer:
Thus, the correct answer is B, C, E Only, which corresponds to option (A).
