Question: Which of the following transposable elements are NOT found in plants? (IFFCO 2022)
Options:
Sigatoka
Fusarium wilt
Bunchy top
Panama wilt
✅Explanation:
-Prevalence: Sigatoka is widespread across banana-growing regions in India, affecting a large proportion of plantations.
-Impact on Yield: Severe Sigatoka infections can cause significant yield losses by reducing the photosynthetic capacity of the leaves, leading to smaller and fewer fruits.
-Economic Losses: The disease necessitates frequent fungicide applications, increasing production costs for farmers and potentially impacting the environment.
-Favorable Conditions: The warm and humid climate in many parts of India favors the development and spread of Sigatoka.
