High yield and crop-specific insecticide through toxic proteins

Vedclass · Answer

(D) $BT$ cotton is a genetically modified organism $(GMO)$ created by introducing the $cry$ genes from the bacterium $Bacillus$ $thuringiensis$ into the cotton plant. These genes encode for crystal $(Cry)$ proteins,which are toxic to specific insect pests like lepidopterans,coleopterans,and dipterans. When these insects ingest the plant tissue,the alkaline $pH$ of their gut activates the protoxin into its active toxic form,leading to the death of the insect. Thus,$BT$ cotton acts as a biological insecticide,providing high yield by protecting the crop from pest damage.
