This Small Business Innovation Research Phase I project will generate novel parental lines of hybrid industrial corn. These F1 hybrids, grown by U.S. farmers, will produce F2 seeds with much higher levels of starch and no embryos. This innovation will allow for an easier and more cost effective processing of corn at the plant for all industrial applications of starch. We have dual research objectives: i) the genetic engineering of germless kernels, and ii) the timely expression of the germless trait to the F2 seeds. Molecular constructs have been prepared and will be transformed into corn during Phase I. This technology will facilitate starch extraction leading to a cleaner stream of starch and capturing value for farmers, processors and end-users.The broader impact/commercial potential of this project includes the following societal and economical benefits: i) the development of new and cost-effective industrial methods to extract starch from corn and other crops; ii) the partitioning of the U.S. crop into industrial (starch for biomaterials, ethanol and other applications) and conventional (feed and food) acreage for more efficient land use; iii) reducing the need for petroleum by replacing products historically derived from oil with eco-friendly bioplastics, biofilms and other biomaterials derived from starch; and iv) an opportunity to lower fertilizer inputs to the corn crop when grown to supply the industrial production of starch. Phase I is designed to achieve all these achievements by merging and further developing technologies from plant molecular biology, seed physiology, cereal processing, fermentation biology and process engineering.

这个小企业创新研究第一阶段项目将产生新的杂交工业玉米亲本系。这些由美国农民种植的F1杂交品种将产生淀粉含量高得多的F2种子，而且没有胚胎。这一创新将使玉米在工厂的加工更容易，成本效益更高，适用于淀粉的所有工业应用。我们有两个研究目标：1)无芽核的基因工程，2)无芽性状在F2种子上的及时表达。分子结构已经准备好，并将在第一阶段转化为玉米。这项技术将促进淀粉提取，导致更清洁的淀粉流，并为农民、加工商和最终用户创造价值。该项目的广泛影响/商业潜力包括以下社会和经济效益：i)开发新的和具有成本效益的工业方法，从玉米和其他作物中提取淀粉；ii)将美国作物划分为工业（用于生物材料、乙醇和其他应用的淀粉）和传统（饲料和食品）种植面积，以更有效地利用土地；Iii)减少对石油的需求，用从淀粉中提取的生态友好型生物塑料、生物膜和其他生物材料取代以往从石油中提取的产品；iv)当玉米种植以供应淀粉的工业生产时，有机会降低肥料投入。第一阶段旨在通过融合和进一步发展植物分子生物学、种子生理学、谷物加工、发酵生物学和工艺工程等技术来实现所有这些成就。
