Scientists Introduce cry1Ab into Cotton to Enhance Pest Resistance
March 18, 2011| |
One of the benefits of plant biotechnology is the introduction of genes from an unrelated source into an important crop to develop resistance traits. G.A. Khan from the Cotton Research Institute in Pakistan, together with other scientists, inserted cry1Ab gene from soil bacterium into a local cotton cultivar (MNH-93) from Pakistan through particle bombardment. Transgene integration and expression were confirmed through polymerase chain reaction (PCR) and Dot blot analyses. Amount of Bt protein was also determined, which was found to be ranging from 0-1.35% of the total protein. Transgenic plants were grown in greenhouse and field conditions to assess their field performance, and results showed that the transgenic lines have 40-60% level of resistance against lepidopteran pests.
