The process for obtaining the T plants, which was carried out
by Monsanto Co., is as follows. To transform the soybean plants,
the bioballistics technique was used, which involves accelerated
metal particles coated with genetic material. The plants received
the cp4 EPSPS gene, which encodes the CP4 EPSPS enzyme from
the soil bacteria Agrobacterium sp. strain CP4. The insert for
transformation, or the T cassette, contains a part of the
Cauliflower Mosaic Virus promoter (CaMV 35S) followed by the
transit peptide of the chloroplast of the epsps (CTP EPSPS) of a
hybrid petunia, the cp4 epsps coding sequence, and part of the nos
transcription terminator from Agrobacterium tumefaciens nopaline
synthase
