ASU's Lisko receives INBRE Student Travel award
for biomedical research work
August 7, 2008 --
Katherine Lisko of Stuttgart, Ark., a student at Arkansas
State University, received the Student Travel Award from the IDeA
Networks of Biomedical Research Excellence (INBRE) Program of the
National Center for ResearchResources.
Lisko accepted a $1,000 award at the symposium August 6 in Washington,
The award is based on her work, “Elevated Vitamin C Enhances Growth,
Stress Tolerance, and Phytoremediation Potential in Arabidopsis,”
authored by Lisko, R. Shea Harris, and Dr. Argelia Lorence, assistant
professor of Metabolic Engineering in the Arkansas Biosciences Institute
(ABI) on the ASU campus.
Recipients of the award were selected based on rating and peer review of
a submitted abstract and were evaluated by the scientific committee
organizing the Second Biennial National IDeA Symposium of Biomedical
In Lisko’s study under Dr. Lorence, she worked with lines of the model
plant Arabidopsis, commonly known as mouse-ear cress. These plant lines
were engineered by Dr. Lorence’s lab to contain elevated levels of
vitamin C, a key antioxidant that is essential for human and plant
Lisko has been studying how the high vitamin C lines respond when they
are exposed to stressful conditions. The Lorence lab found that plants
with elevated vitamin C grow better, are more vigorous, and better
tolerate stressful conditions such as heat, cold, salt, high light and
the herbicide Paraquat.
R. Shea Harris, an environmental science master’s degree student who
also works in Dr. Lorence’s lab, found that these plants are tolerant to
pollutants, such as trichloroethylene and pyrene, commonly found in the
water and soil of various sites in the United States.
Funding for the project was obtained by Dr. Lorence through a sub-award
from the National Institutes of Health Grant from INBRE and the program
of the National Center for Research Resources.
Lisko is the daughter of Freddy and Babs Lisko of Stuttgart. She holds a
bachelor of science degree in forensic science from Arkansas State and
currently works in Dr. Lorence’s lab. She has been accepted into ASU’s
molecular biosciences graduate program to obtain her doctoral degree.
