SYN-IR6Ø4-5×MON-ØØØ21-9 has stacked insect resistant and herbicide tolerant maize produced by conventional cross breeding of two genetically engineered parental varieties (MIR604 and GA21).

The parental MIR604 maize variety (OECD unique identifier SYN-IR6Ø4-5) was genetically modified by introducing the cry3A gene from Bacillus thuringiensis ssp. kumamotoensis, which codes for a  Bt-toxin (Cry3A) and confers resistance to western corn rootworm (Diabrotica virgifera virgifera), northern corn rootworm (Diabrotica longicornis barberi) and other related coleopteran species. Expression of the pmi gene in MIR604 from the bacterium Escherichia coli allows this line to use mannose as a carbon source through production of the PMI protein, and is used as a selectable marker.

The parental GA21 line (OECD unique identifier MON-ØØØ21-9) was created by modifying the endogenous maize epsps gene through site-directed mutagenesis, such that its encoded enzyme was insensitive to inactivation by glyphosate, and inserting it into the inbred AT maize variety. The modified maize GA21 line permits farmers to use glyphosate-containing herbicides for weed control in the cultivation of maize.

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.

  • Cross breeding
Some of these genetic elements may be present as fragments or truncated forms. Please see notes below, where applicable.
Inserted genes (MIR604): 
1) cry3A-gene from Bacillus thuringiensis ssp. kumamotoensis. This gene codes for a Bt-toxin, which confers resistance to western corn rootworm (Diabrotica virgifera virgifera), northern corn rootworm (Diabrotica longicornis barberi) and other related coleopteran species.

2) Marker gene pmi-gene from the bacterium Escherichia coli. The LMO plant harboring this gene expresses a marker protein, PMI, that allows the plant to utilise mannose as a carbon source, acting as a selectable marker.

Inserted gene (GA21): 
m epsps. This is a mutated form of the epsps gene derived from maize (Zea mays). The cp4 epsps gene encodes for a version of EPSPS that is highly tolerant to inhibition by glyphosate.

Additional Information
This plant is a product of traditional plant breeding, and therefore is not automatically subject to regulation in all jurisdictions as are transgenic plants resulting from recombinant DNA technologies. Certain jurisdictions may request notification in advance of the release of a stacked hybrid, or may request information to conduct an environmental and food safety assessment.
