Question

Match List I with List II
List I (Powdery mildew Tribe):
A. Tribe Erysipheae
B. Tribe Phyllactinieae
C. Tribe Golovinomyceteae
D. Tribe Cystotheceae
E. Tribe Blumeria
List II (Genera):
I. Blumeria
II. Podosphaera
III. Brasiliomyces
IV. Leveillula
V. Neoerysipheae
Choose the correct answer from the options given below:

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

Hint:

Tribe Blumerieae is a monotypic tribe containing only the genus Blumeria. This makes E - I a definitive match, which immediately narrows down the options.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Powdery mildews (Order Erysiphales) are obligate biotrophic fungi.
They are classified into distinct tribes based on morphological characteristics of their sexual stage (chasmothecium appendages and asci number) and asexual stage (anamorph type).

Step 2: Detailed Explanation:
Let us establish the tribal classifications for each genus:
A. Tribe Erysipheae: This tribe includes genera such as Erysiphe and Brasiliomyces.
Therefore, A matches with III (Brasiliomyces).
B. Tribe Phyllactinieae: This tribe is characterized by chasmothecia with needle-like appendages with bulbous bases.
It includes the genera Phyllactinia and Leveillula.
Therefore, B matches with IV (Leveillula).
C. Tribe Golovinomyceteae: This tribe includes the genus Neoerysiphe (represented as Neoerysipheae in List II).
Therefore, C matches with V (Neoerysipheae).
D. Tribe Cystotheceae: This tribe is characterized by chasmothecia containing a single ascus.
It includes the genus Podosphaera.
Therefore, D matches with II (Podosphaera).
E. Tribe Blumeria (or Blumerieae): This tribe is represented by the monotypic genus Blumeria (e.g., Blumeria graminis, which causes powdery mildew of cereals).
Therefore, E matches with I (Blumeria).

Step 3: Final Answer:
The matches are: A - III, B - IV, C - V, D - II, E - I. This corresponds to Option (C).
