alleryBt cotton is resistant to BOLLWORM pests because it carries a gene from:
ABacillus thuringiensis (a soil bacterium)
BMycobacterium tuberculosis (causes TB)
CSaccharomyces cerevisiae (a baker's yeast)
DAgrobacterium tumefaciens (plant pathogen)
Answer & Solution
Correct answer: A. Bacillus thuringiensis (a soil bacterium)
The Cry gene from BACILLUS THURINGIENSIS encodes a toxin (delta-endotoxin) lethal to lepidopteran insects (bollworms).
Inserted into cotton (and brinjal), this gene confers natural pest resistance, reducing pesticide spray.
