In this study, the two genes involved are 5-enolphyruvylshikimate-3-phosphate gene synthase (EPSPS) and Cry1Ab genes. The presence of EPSPS gene identifies the Roundup Ready event in soybean products.
According to AGBIOS, Roundup Ready Soya contains a glyphosate tolerant form of the plant enzyme 5-enolphyruvylshikimate-3-phosphate gene synthase (EPSPS) isolated from the common soil bacterium, Agrobacterium tumafaciens strain CP4 (CP4 EPSPS).
