Clemson-led team makes breakthrough in controlling Bt resistance in pests

CLEMSON - Science, America's most respected research journal, today (Aug. 3) reports the breakthrough findings of a scientific team led by a Clemson University researcher. The results of the team's work may lead to multi-millon dollar savings to the cotton industry and prolong the useful life of crops genetically modified to resist pests.

Lead author Linda J. Gahan, an assistant professor of biological sciences at Clemson, and co-authors Fred Gould from North Carolina State University and David G. Heckel of the University of Melbourne, Australia, found an efficient method to track genetically the tobacco budworm's efforts to become resistant to biotechnological pest controls.

"We have identified a gene in the budworm which binds Bt-toxin produced in genetically modified plants like cotton," Gahan said. "If the gene is altered or defective in the insect, the insect will not bind the toxin and effectively becomes resistant to it. Knowing the gene involved in resistance allows us to develop a DNA test for monitoring resistance in field population of insects."

The tobacco budworm is a major pest of cotton and other field crops in the Americas. Over the years, it has developed resistance to chemical pesticides. The problem was solved through biotechnology when researchers added a gene to cotton from bacteria that naturally produces an insect toxin. The result was a genetically modified species, called Bt cotton, that resists the tobacco budworm and other insects.

Concerns took shape that the battle against the budworm was not a decisive victory. Under laboratory conditions, strains of tobacco budworms could be made Bt-resistant by feeding the insects a high-dose diet of the toxin. Federal regulators acted.

They required non-Bt cotton to be planted alongside of Bt cotton, diminishing the chances of budworms taking a Bt-rich diet in the fields. The question was h
