Researchers Develop GM Sugarcane with Pyramided Insecticidal Proteins
March 14, 2018| |
Scientists developed a variety of transgenic sugarcane expressing two Bt proteins to provide resistance against sugarcane borer. Their findings are published in Tropical Plant Biology.
One of the major pests of sugarcane in the Americas is sugarcane borer (Diatraea saccharalis). In 2017, Brazil's Comissão Técnica Nacional de Biossegurança approved the commercial use of Bt sugarcane expressing one Bt protein (Cry1Ab) developed by Centro de Tecnologia Canavieira (CTC). In a study conducted by Monsanto Brazil researchers, two Bt proteins (Cry1Ab and Cry2Ab) with different modes of action were expressed in sugarcane to maximize protection against sugarcane borer. They also setup a large refuge in addition to the use of a selection marker that added the glyphosate tolerance trait to a final event.
Based on the results, it was demonstrated that it is possible to use Bt proteins to provide improved protection against sugarcane borer attacks.
