Evaluation of transgenic crops under field conditions is a fundamental step for the production of genetically engineered varieties. In order to determine if there is pollen dispersal from transgenic to nontransgenic soybean plants, a field release experiment was conducted in the Cerrado region of Brazil. Nontransgenic plants were cultivated in plots(More)
The present study evaluated the use of γ-radiation to physically remove selective marker genes previously introduced into the soybean genome. Homozygous seeds from a transgenic soybean line carrying the gus and ahas transgenes were irradiated with γ-rays. Six plants presenting a deleted gus gene were analyzed by Southern blot to confirm removal of both ahas(More)
