The Iowa Corn Promotion Board is the recipient of a newly issued patent from the U.S. Patent and Trademark Office. This is the first U.S. patent that the Iowa Corn Promotion Board has received for its work in nitrogen use efficiency in corn and related to transgenic plants that have increased nitrogen use efficiency, and/or increased yield using a patented gene.

Specifically, patent 8,692,070, Plants with Improved Nitrogen Utilization and Stress Tolerance demonstrates Iowa Corn's commitment to improving farmer productivity even to the gene level.

"The Iowa Corn Promotion Board collaborated with Strathkirn Inc. and Athenix Corp. to develop improved corn plants that are more efficient in using nitrogen fertilizer," said Larry Klever, a farmer from Audubon and chair of the Iowa Corn Research and Business Development Committee. "This new trait could result in improved economics on the farm, reduced impact on the environment and reduced energy requirements to grow a corn crop."

The objectives of the research are either to increase yield without increasing the amount of nitrogen fertilizer or obtain the same yield with less fertilizer. Data indicates this patented gene assimilates more nitrogen and increases kernel number, which could translate to greater yields for Iowa farmers.

By patenting this technology, the Iowa Corn Promotion Board is able to provide protection for partners who would like to license this technology. "The goal is to get this trait licensed and commercialized by seed companies for commercialization so that farmers, like me, can benefit," said Klever.

The Plants with Improved Nitrogen Utilization and Stress Tolerance patent number is 8,692,070 and was issued on April 8, 2014. A patent for this technology has also been awarded to the Iowa Corn Promotion Board by South Africa. Patents for this gene in other countries are still pending approval of the respective patent offices.
