Abstract:
... MON 87460 (D1) maize contains a gene that expresses the cold shock protein B (CSPB) from Bacillus subtilis to confer a yield advantage when yield is limited by water availability. This study evaluated the composition of grain from the D1-containing combined-trait maize hybrids D1 × NK603, D1 × MON 89034 × NK603, and D1 × MON 89034 × MON 88017. These stacks offer a combination of insect protec ...

Abstract:
... New transgenic (GM) crops are subjected to extensive safety assessments that include compositional comparisons with conventional counterparts as a cornerstone of the process. The influence of germplasm, location, environment, and agronomic treatments on compositional variability is, however, often obscured in these pair-wise comparisons. Furthermore, classical statistical significance testing can ...

Monsanto Co. has developed biotechnology-derived MON 87427 maize with tissue-selective glyphosate tolerance to facilitate the production of hybrid maize seed. MON 87427 utilizes a specific promoter and intron combination ...

Abstract:
... In this study, we show that compositional differences in grain harvested from genetically modified (GM) maize hybrids derived from near-isogenic trait-positive and trait-negative segregant inbreds are more likely related to backcrossing practices than to the GM trait. To demonstrate this, four paired GM trait-positive (NK603: herbicide tolerance) and trait-negative near-isogenic inbred male lines ...

Abstract:
... Here, we show that differences between genetically modified (GM) and non‐GM comparators cannot be attributed unequivocally to the GM trait, but arise because of minor genomic differences in near‐isogenic lines. Specifically, this study contrasted the effect of three GM traits (drought tolerance, MON 87460; herbicide resistance, NK603; insect protection, MON 89034) on maize grain composition relati ...

Abstract:
... Advances in biotechnology continue to drive the development of a wide range of insect-protected, herbicide-tolerant, stress-tolerant, and nutritionally enhanced genetically modified (GM) crops, yet societal and public policy considerations may slow their commercialization. Such restrictions may disproportionately affect developing countries, as well as smaller entrepreneurial and public sector ini ...
