Bangladesh on 31 October 2013 approved
the commercial cultivation of transgenic Bt brinjal. With this decision
Bangladesh became the first country in
South Asia to cultivate the genetically modified food crop.
National
Committee on Biosafety (NCB), the highest regulatory body for GM crops in
Bangladesh, officially approved the Bt brinjal varieties. With this step,
Bangladesh becomes the 29th country in the world to grow GM crop. In
South Asia, India, Pakistan and Myanmar grow GM crop cotton. With the NCB nod,
Bangladesh becomes the first in the region to grow a GM food crop.
Four
Bt brinjal varieties (Bt brinjal-1, 2, 3 and 4) have been approved by
the Bangladesh Government for limited scale cultivation with some conditions.
BARI (Bangladesh Agricultural Research Institute) had developed these Bt
brinjal varieties incorporating Indian company Mahyco’s proprietary gene
construct technology.
Maharashtra-based
seed company-Mahyco had transferred its Bt brinjal technology to BARI
way back in 2005-06 through a USAID-funded and Cornell University-managed Agricultural
Biotechnology Support Project.
In
GM crops, the genetic material (DNA) is altered for improvements in its
qualities. Bt Brinjal, for instance, has been inserted with a natural bacterial
protein which makes it resist pests.
Bt
brinjal contains a foreign Cry1Ac gene derived from a soil bacterium,
Bacillus thuringiensis or Bt. This gene synthesises a protein toxic to the
fruit and shoot borer (FSB), a destructive pest. The gene gives the crop a built-in
resistance to FSB, reducing reliance on spraying pesticides.
