The terms ‘cry1Ac, and 'cry2Ab’ sometimes mentioned in the news recently are related to
Correct
The Genetic Engineering Appraisal Committee (GEAC) is currently planning to recommend environmental release of a genetically modified (GM) herbicide tolerant cotton of German multinational company Bayer AG. It had earlier approved the environmental clearance of Delhi University’s transgenic hybrid mustard DMH-11 along with its parental lines.
Bollgard II Roundup Ready Flex (BG-II RRF) is a transgenic cotton having three alien genes.
Two of the alien genes – cry1Ac and cry2Ab – were isolated from a soil bacterium Bacillus thuringiensis. These genes have proteins that are harmful for American bollworm, spotted bollworm and tobacco caterpillar insect pests.
The third gene – cp4-epsps – was obtained from another soil bacterium Agrobacterium tumafaciens. Its inclusion makes the cotton crop “tolerant” to the harmful herbicide glyphosate, which does not distinguish between the crops and weeds.
