The modified soybean contains two gene cassettes: Agrobacterium tumefaciens 5-enolpyruvylshikimate-3-phosphate synthase (epsps) and Streptomyces viridochromogenes phosphinothricin N-acetyltransferase (pat).

Transcription of the epsps commences from a Glycine max elongation factor 1 alpha promoter and terminates at a Pisum sativum ribulose-1,5-bisphosphate carboxylase small subunit terminator. An Arabidopsis thaliana chloroplast transit peptide 2 sequence was added to the 5' end of epsps coding sequence to target the translated protein to the chloroplast. Due to the nature of the promoter, high levels of transcription are expected.

Transcription of the pat coding sequence under control of a Cauliflower mosaic virus (CaMV) 35S promoter and a CaMV terminator. Elevated levels of transcription of pat are expected due to the CaMV 35S promoter. The protein is expected to remain in the cytoplasm of the plant cells.
