Washington University unveils draft sequence of c...( Feb. 25 2008 -- A team of scientists...)

Feb. 25, 2008 -- A team of scientists led by Washington University in St. Louis has begun to unlock the genetic secrets of corn, a crop vital to U.S. agriculture. The researchers have completed a working draft of the corn genome, an accomplishment that should accelerate efforts to develop better crop varieties to meet society's growing demands for food, livestock feed and fuel.

Corn, also known as maize, underlies myriads of products, from breakfast cereal, meat and milk to toothpaste, shoe polish and ethanol.

The genetic blueprint will be announced on Thursday, Feb. 28, by the project's leader, Richard K. Wilson, Ph.D., director of Washington University's Genome Sequencing Center, at the 50th Annual Maize Genetics Conference in Washington, D.C.

"This first draft of the genome sequence is exciting because it's the first comprehensive glimpse at the blueprint for the corn plant," Wilson says. "Scientists now will be able to accurately and efficiently probe the corn genome to find ways to improve breeding and subsequently increase crop yields and resistance to drought and disease."

The $29.5 million project was initiated in 2005 and is funded by the National Science Foundation (NSF), the U.S. Department of Agriculture and the U.S. Department of Energy. "Corn is one of the most economically important crops for our nation," says NSF director Arden L. Bement Jr. "Completing this draft sequence of the corn genome constitutes a significant scientific advance and will foster growth of the agricultural community and the economy as a whole."

The team working on the endeavor, including scientists at the University of Arizona in Tucson, Cold Spring Harbor Laboratory in New York and Iowa State University, has already made the sequencing information accessible to scientists worldwide by depositing it in GenBank, an online public DNA database. The genetic data is also available at maizesequ
