Project Title

GRO FORTH: Genomic Resource Optimization for Forest Health

Project Description

This project aims to develop a reference quality genome sequence for Fraser fir trees and tissue specific gene expression information of loblolly pine trees. This information will refine current knowledge of defense gene sequences in these species and help identify sequences for the development of genetically-improved Fraser fir and loblolly pine trees, which will positively impact forest health and Christmas tree production in the southeastern United States and beyond. 

Researchers will also recruit and educate a graduate student to apply molecular technologies for rapid improvements to forest health and productivity. With increasing temperatures driving unprecedented numbers of outbreaks of forest insect pests and diseases, the recruitment and training of well-trained specialists that can develop and implement these technologies is the primary means to combat the inevitable outcomes associated with a changing climate.

Principal Investigators

• Justin Whitehill, director
• Ross Whetten
• Jack Wang 

Collaborators

This project unites faculty members from across the Department of Forestry and Environmental Resources who have complimentary strengths in the area of forest genetics and genomics. 

Expected Outcomes

• A more robust, efficient and sustainable Christmas tree industry in the Southeast
• Development of a reference-quality genome for Fraser fir and tissue-specific gene expression libraries for loblolly pine to support future research
• Utilization and evaluation of genomic resources to advance understanding of conifer defense genes in Fraser fir and loblolly pine
• Identification of major and minor components of loblolly pine and Fraser fir oleoresin
• Target gene sequences of oleoresin metabolites to enable CRISPR-based genome editing for enhanced Fraser fir clones and improved loblolly pine forest health
• Training of a graduate student in modern genomics techniques to improve forest health and productivity
