DP202216 maize was genetically modified to increase and extend the expression of the zmm28 gene relative to native zmm28 gene expression, resulting in plants with enhanced grain yield potential. Standard nutritional and compositional parameters for maize grain and forage (e.g., proximates, fiber, minerals, amino acids, fatty acids, vitamins, anti-nutrients, secondary metabolites) from DP202216 maize were compared to grain and forage from non-modified near-isoline maize (control). Three amino acids (glycine, methionine, and serine) and two vitamins (vitamin B1 and vitamin B3) were statistically different between DP202216 and control maize grain but were not statistically different when adjusted using the false discovery rate method. These analyte values also fell within the ranges of natural variation of non-modified commercial maize varieties supporting that statistical differences were not biologically relevant. The composition of grain and forage from DP202216 maize is comparable to grain and forage from non-modified maize with a history of safe use.

转基因DP202216玉米的饲料和谷物成分与未改良的常规玉米（Zea mays L.）相同。

相对于天然zmm28基因表达，对DP202216玉米进行了基因修饰，以增加和扩展zmm28基因的表达，从而使植株具有更高的谷物产量潜力。将来自DP202216玉米的玉米谷物和牧草的标准营养和成分参数（例如，接近，纤维，矿物质，氨基酸，脂肪酸，维生素，抗营养剂，次生代谢产物）与未经修饰的近等值线的谷物和牧草进行了比较玉米（对照）。DP202216和对照玉米籽粒中的三种氨基酸（甘氨酸，蛋氨酸和丝氨酸）和两种维生素（维生素B1和维生素B3）在统计学上是不同的，但使用错误发现率方法进行调整时，在统计学上没有差异。这些分析物值也落在未修饰的商业玉米品种的自然变异范围内，支持统计差异与生物学无关。具有安全使用历史的DP202216玉米谷物和牧草的成分与未经修饰的玉米谷物和牧草的成分相当。
