The maize (Zea mays) was modified for tolerance to herbicides. For tolerance to glyphosate, the maize expresses Agrobacterium tumefaciens 5-enolpyruvylshikimate-3-phosphate synthase, which binds the glyphosate with low affinity and allows for the continued function of the shikimate pathway. For tolerance to glufosinate, the maize expresses Streptomyces viridochromogenes phosphinothricin acetyltransferase, which inactivates the glufosinate ammonium herbicides through acetylation.
The term “Recipient organism” refers to an organism (either already modified or non-modified) that was subjected to genetic modification, whereas “Parental organisms” refers to those that were involved in cross breeding or cell fusion.

The modified maize expresses two gene cassettes: Streptomyces viridochromogenes phosphinothricin N-acetyltransferase (pat) and Agrobacterium tumefaciens 5-enolpyruvylshikimate-3-phosphate synthase (cp4-epsps).
The pat coding sequence is under control of the a Cauliflower mosaic virus 35S promoter and terminator. High levels of expression are expected due to the nature of the promoter.
The cp4-epsps sequence is under control of an Oryza sativa actin 1 promoter and A. tumefaciens nopaline synthase terminator. An Arabidopsis thaliana chloroplast transit peptide 2 sequence was included between the promoter and pat sequence to target the PAT protein to the chloroplast. High levels of expression in all tissues are expected due to the constitutive nature of the promoter.
