Biology Researcher Receives Outstanding Article Award

C.L. Cheng, associate professor of biological sciences in the University of Iowa College of Liberal Arts and Sciences, has received the 2003 Outstanding Article award from the journal Weed Science.

Her article, "Genetically Engineered Self-Distructions: An Alternative to Herbicides for Cover Crop Systems," was written with co-author Marisha Stanislaus, who earned her doctorate in the biological sciences from the UI in 2001 and currently is a researcher at GlaxoSmithKline's Philadelphia facility. The authors will be honored at the Weed Science Society of America's (WSSA) annual meeting in February 2004 in Kansas City, Mo.

Cheng, who has been at the UI since 1990, is being recognized for her research in the development of a cover crop system. The potential benefits of Cheng's work include decreasing the application of herbicides, protecting soils and replenishing soil nitrogen.

"I am delighted to hear that this USDA-funded work has been recognized," said Cheng. "Our proof-of-concept research, hopefully will be further developed by other researchers into a practical cover crop system."
