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. A description is available at:
