The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Cotton Leaf Curl Virus (CLCuV) is a devastating plant pathogen that primarily affects cotton crops (Gossypium hirsutum), causing severe leaf curling, vein thickening, and stunting, which leads to massive yield losses.
Step 2: Detailed Explanation:
Let us evaluate each of the given statements about CLCuV:
- Statement (A): Cotton Leaf Curl Virus belongs to the genus Begomovirus of the family Geminiviridae.
It is characterized by a circular, single-stranded DNA (ssDNA) genome, making this statement correct.
- Statement (B): The virus is transmitted in nature by the insect vector whitefly (Bemisia tabaci) in a persistent, circulative manner, making this statement correct.
- Statement (C): CLCuV is a regulated plant virus of immense quarantine importance in cotton-growing regions globally to prevent its introduction into disease-free zones, making this statement correct.
- Statement (D): In India, Cotton Leaf Curl Disease (CLCuD) was first reported in the early 1990s in Rajasthan and Punjab.
Its distribution is primarily restricted to the northwestern cotton-growing zone of India (comprising Punjab, Haryana, and Rajasthan) which directly adjoins the Pakistan border, as the disease is highly endemic in Pakistan's cotton-growing belt.
Therefore, all four statements (A), (B), (C), and (D) are correct.
Step 3: Final Answer:
The correct option is (C), representing (A), (B), (C) and (D).
