Question

Match List I with List II 

Choose the correct answer from the options given below: 
 

• A. A-III, B-IV, C-II, D-V, E-I
• B. A-II, B-IV, C-III, D-V, E-I
• C. A-III, B-V, C-II, D-IV, E-I
• D. A-II, B-V, C-I, D-IV, E-III

Hint:

Butler = India/Mycology.
De Bary = Late Blight/Fungi.
Beijerink = Viruses.
Flor = Genetics (Gene-for-Gene).

Answer 1

The Correct Option is B

Step 1: Understanding the Question:
The question asks to match major scientists in the history of plant pathology and microbiology with their key contributions or titles.

Step 2: Detailed Explanation:

• Anton de Bary (A-II): Known as the "Father of Modern Mycology." He proved that Phytophthora infestans was the causal organism of Late Blight of Potato.

• M.W. Beijerink (B-IV): He proved that the cause of tobacco mosaic was a "contagium vivum fluidum" (contagious living fluid) and is credited with naming them Viruses.

• T. J. Burrill (C-III): He was the first to prove that bacteria can cause plant disease, specifically by identifying Erwinia amylovora as the cause of Fire Blight.

• E. J. Butler (D-V): The first Imperial Mycologist of India and the "Father of Indian Mycology." He authored the seminal book "Fungi and Disease in Plants."

• H.J. Flor (E-I): Proposed the Gene-for-Gene hypothesis in flax rust, stating that for every resistance gene in the host, there is a corresponding avirulence gene in the pathogen.
Final Answer:
The matching is A-II, B-IV, C-III, D-V, E-I. This corresponds to option (B).
