Key discovered to cold tolerance in corn
Date:8/29/2008

Demand for corn -- the world's number one feed grain and a staple food for many -- is outstripping supply, resulting in large price increases that are forecast to continue over the next several years. If corn's intolerance of low temperatures could be overcome, then the length of the growing season, and yield, could be increased at present sites of cultivation and its range extended into colder regions.

Drs. Dafu Wang, Archie Portis, Steve Moose, and Steve Long in the Department of Crop Sciences and the Institute of Genomic Biology at the University of Illinois may have made a breakthrough on this front, as reported in the September issue of the journal Plant Physiology.

Plants can be divided into two groups based on their strategy for harvesting light energy: C4 and C3. The C4 groups include many of the most agriculturally productive plants known, such as corn, sorghum, and sugar cane. All other major crops, including wheat and rice, are C3. C4 plants differ from C3 by the addition of four extra chemical steps, making these plants more efficient in converting sunlight energy into plant matter.

Until recently, the higher productivity achieved by C4 species was thought to be possible only in warm environments. So while wheat, a C3 plant, may be grown into northern Sweden and Alberta, the C4 grain corn cannot. Even within the Corn Belt and despite record yields, corn cannot be planted much before early May and as such is unable to utilize the high sunlight of spring.

Recently a wild C4 grass related to corn, Miscanthus x giganteus, has been found to be exceptionally productive in cold climates. The Illinois researchers set about trying to discover the basis of this difference, focusing on the four extra chemical reactions that separate C4 from C3 plants.

Each of these reactions is catalyzed by a protein or enzyme. The enzyme for one of these steps, Pyruvate Phosphate Dikinase, or PPDK for shor
