'A-maize-ing' discovery could lead to higher corn yields for food, feed and fuel
Date:3/25/2010

Pittsburgh, PA -- Scientists may have made an "a-maize-ing" discovery that could lead to higher corn yields in the United States. In a new research report published in the March 2010 issue of the journal Genetics (http://www.genetics.org), scientists used tropical maize from Mexico and Thailand to discover chromosome regions responsible for detecting seasonal changes in flowering time (called the "photoperiod response"). This discovery may lead to higher crop yields, improved disease resistance, and heartier plants able to withstand severe weather. As one of the United States' largest crops, corn is used for food, feed, sweetener, fuel, plastics, and more.

"Photoperiod response is the major barrier to using tropical maize for the improvement of temperate maize varieties," said James B. Holland, Ph.D, a researcher involved in the work from the U.S. Department of Agriculture, Agricultural Research Service, Plant Science Research Unit at North Carolina State University. "By understanding the genetics of this barrier, we hope to be able to overcome it more quickly to broaden the genetic diversity of temperate maize."

To discover these important regions of the plant's genome, researchers interbred two tropical, photoperiod-sensitive corn lines (one from Mexico; one from Thailand) with two photoperiod-insensitive corn lines from the United States, and grew out hundreds of progeny lines in North Carolina (long day-length summers) and in Florida (short day-length winters). Lines with strong photoperiod response were identified as those flowering much later in North Carolina, compared to Florida. Researchers then genetically mapped all of the lines and identified DNA markers associated with the photoperiod response. The genomic regions carrying the major photoperiod response genes were then identified.

In addition to allowing for improved strains of domestic corn, the research also is importan
