The maize (Zea mays) was modified for insect resistance and herbicide tolerance. For resistance to Lepidoptera pests, the maize expresses Bacillus thuringiensis vegetative insecticidal protein 3Aa19 (a derivative of vegetative protein 3A), which causes gut paralysis and lysis of epithelium cells of larvae. For tolerance to glufinosate, the maize expresses Streptomyces viridochromogenes phosphinothricin N-acetyltransferase, which inactivates the herbicide 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 contains two gene cassettes: Streptomyces viridochromogenes phosphinothricin N-acetyltransferase (pat) and Bacillus thuringiensis vegetative insecticidal protein 3Aa19 (vip3Aa19).
The pat coding sequence is under control of a maize ubiquitin 1 promoter and an Agrobacterium tumefaciens nopaline synthase terminator. High levels of transcription are expected due to the constitutive nature of the promoter.
The vip3Aa19 sequence is under control of a Cauliflower mosaic virus 35S enhanced promoter and an A. tumefaciens nopaline synthase terminator. High levels of transcription are expected due to the enhanced promoter and a maize heat shock protein 70 intron, which is also present to further enhance the expression of the coding sequence.
Note
- the vip3Aa19 sequence is a derivative of the vip3A sequence. The vip3Aa19 sequence has been codon optimized for expression in plants and contains an amino acid substitution (lysine was replaced with glutamate at position 284).
