Dr. Davis granted provisional patent

Dr. George Davis, associate professor, Department of Biological and Allied Health Sciences, and his colleague Dr. Mark Stocksdale, Department of Chemistry at Earlham College, have been granted a provisional patent for their invention  “'Trojan Horse' targeted delivery system for crop species” as listed on the Penn State “Technologies Available for Licensing” page. This invention uses the iron uptake system found in grasses to deliver nutrients / minerals, growth regulators, herbicides, and fertilizers to a wide range of plants that have been genetically engineered to express the iron transporter. This technology has the potential to promote more vigorous growth in crop plants and to reduce the detrimental environmental impacts of fertilizers. The provisional patent allows protection for the development of the technology until April, 2017.
