SU Ag Center Receives New Research Grant from USDA-NIFA

Baton Rouge, LA - SU Ag Center has recently received $479,672 funding for three years (2014-2017) from USDA/National Institute of Food and Agriculture (NIFA) Capacity Building Grant Program to undertake a multi-disciplinary research entitled “Urban Tree Interception of UV (A/B) Radiation and Its Genetic Consequences.” The project director is Dr. Yadong Qi, professor of urban forestry and the co-project directors include Dr. Wei Gao, professor and director of USDA UV-B Monitoring and Research Program at Colorado State University, Fort Collins; Dr. Rao Uppu, professor and chairman of environmental toxicology, SUBR; Dr. Wesley Gray, professor of chemistry, SUBR; Dr. Kit L. Chin, professor of horticulture, SU Ag Center; and Dr. Shuju Bai, associate professor of computer science at SUBR.

“This multi-institutional and multi-disciplinary research team represents the best partnership and collaboration in the field of UV-B monitoring and research. The team will have two major tasks:  to develop UV (A/B) interception models to understand how forest canopy influences UV radiation in urban environment, and to investigate UV (A/B) induced DNA damage and associated repair mechanisms in selected group of southern broadleaf tree species,” said Dr. Yadong Qi, PD.

The partnership with Dr. Gao’s group at Colorado State University USDA UV-B Monitoring and Research Network will ensure streamlining SU's portable UV-B monitoring station to be coupled with the Network's Baton Rouge ambient monitoring station. Gao’s group will provide system calibration, participate in canopy UV transfer modeling task, host and train graduate and student interns for the project.

Co-PDs Dr. Uppu and Dr. Gray will participate in DNA damage and repair research task and student advisement. Co-PDs Dr. Shuju Bai and Kit L Chin will participate in measurements and modeling of canopy-UV interaction. The project will provide training opportunities to postdoc scientists, graduate students, and undergraduate interns in urban forestry and environmental toxicology.

Stratospheric ozone depletion has resulted in a significant increase in solar ultraviolet radiation (UVB, 280-315nm and UVA, 315-400nm) on the earth's surface. With the future uncertainty of stratospheric ozone recovery and global climate change, there is a critical need for systematic evaluation of UV impacts on trees and urban forest. In the last 15 years, Dr. Yadong Qi with her team has investigated the biochemical and biophysical mechanisms of UV tolerance in more than 30 southern tree species. The outcomes of the early study warrant the continuation to further evaluate tree interception of UV radiation and its resulting genetic consequences.  

“With this new project, we will focus on discovering the role of DNA damage and repairing mechanism in UV-B tolerance in southern trees and modeling the forest canopy influences on UV radiation in urban environment. The results will contribute to a better understanding of UV effects on the trees' genetic stability and quantification of urban forest effects on ground level UV distribution.  Such knowledge is not only important to the scientific community, but also crucial to planning and management and long-term sustainability of urban forests”, said Dr. Qi.

This new project has also received strong endorsements, technical support and collaboration from several well-know research experts in DNA damage/repair and UV climatology, including  Dr. Gordon Heisler, research meteorologist, USDA-FS Northern Research Station, Dr. Joseph Sullivan, professor in plant physiology at University of Maryland-College Park; Dr. John R. Battista, professor in biological science at LSU; and Dr. Ann E. Stapleton, associate professor in genetics at University of North Carolina in Wilmington.

The knowledge of UV-B tolerance capacity in diverse trees will have implications in predicting forest health and ecosystem productivity and in designing effective urban and community forest management strategies. The project will strengthen our institutional research competitiveness and enhance research and student training capabilities at Southern University.
