Introduction
Expand
-
On July 2, 1996, Monsanto Company submitted summary information on several genetically engineered maize lines including MON 831 to support their safety and nutritional assessment. MON 830 is a maize line resulting from genetic modifications to confer tolerance to glyphosate. Glyphosate resistance is due to expression of the protein 5-enolpyruvylshikimate-3-phosphate synthase (CP4 EPSPS). The introduced glyphosate oxidoreductase (GOX) protein also confers glyphosate tolerance.
