MON 87460 contains a gene that expresses cold shock protein B (CSPB) from Bacillus subtilis. Expression of this gene confers a yield advantage when yield is limited by water availability. Compositional analyses of MON 87460 and a conventional corn variety with similar background genetics were conducted on forage and grain harvested from multiple replicated field sites across the United States during the 2006 growing season and across Chile during the 2006−2007 growing season. The U.S. field trials were conducted under typical agronomic practices, whereas the Chilean field trials incorporated a strip-plot design that included well-watered and water-limited treatments. Results demonstrated that levels of the components analyzed were comparable between MON 87460, the conventional control, and the commercially available corn hybrids.
