Current Research Projects
Marker Aided Selection in Trees (2007-2011, USDA): Discovery and genotyping of single-nucleotide polymorphisms have become affordable in recent years, but methods for applying these technologies to tree improvement programs are still lacking. As part of the Conifer Translational Genomics Network (lead by David Neal), my current research focuses on using markers in tree breeding, specifically in prediction of breeding values (using the mixed model theory and BLUP) in Pinus taeda breeding populations (with Ross Whettena and Steve McKeand).
Genetic Improvement of Pine for Fusiform Rust Disease Resistance (Forest Industry): A major threat to pine plantations in the southern USA. Research on fusiform rust disease includes new disease resistant gene discovery in elite pine clones, utilization of resistance genes in pine breeding programs (gene stacking, genotyping and association with disease occurance) and study of host pine genotypes by pathogen interactions (with Ross Whetten, Steve McKeand, Saul Garcia).
Regulation and Modeling of Lignin Biosynthesis (2009-2012, NSF): The mechanisms of regulation of lignin biosynthesis are largely unknown. The project seeks to build models to describe how the pathway is regulated and to reveal new control mechanisms, leading to lignin polymers. The project will use the model woody plant, Populus trichocarpa (black cottonwood) and a systems approach including advanced quantitative methods of genomics, proteomics, biochemistry and structural chemistry, to provide a comprehensive analysis of the regulation of lignin biosynthesis (with Vincent Chiang, Ron Sederoff, Joel Ducoste and John Ralph).
