Read the following and answer the question given below:

Plants having foreign genes in their genome through genetic engineering are called transgenic plants. Genes can be incorporated either through a vector or through direct introduction of DNA. Bt cotton is a genetically modified organism which is pest resistant. It contains gene cry I Ac and cry II Ab of Bacillus thuringiensis. It is used to control lepidopterans, coleopterans and dipterans. Bt cotton can resist cotton bollworm and produce higher yields. Cry genes produce cry protein or Bt toxin. It is an endotoxin which remains as protoxin in plants and converted to active toxin after getting ingested by the insects. Alkaline pH of the insect gut solubilizes the protein crystals, the activated toxin creates pores to the midgut wall of the insects which cause them to die.

Q. What is true about Bt cotton crops?

Detailed Solution for Case Based Questions Test: Biotechnology & Its Applications - Question 11
Bt cotton crops are fungal resistant, insect resistant and drought resistant.
