My laboratory uses genetic and genomic tools to understand the genetic regulation of growth and development of forest trees. A major focus is determining the genes and mechanisms that regulate wood formation. Currently there are three main projects in my lab:

  • We are determining the genetic and molecular mechanisms regulating wood properties important for drought tolerance in trees, in collaboration with Isabelle Henry at the UC Davis Genome Center.
  • In collaboration with Vladimir Filkov at UC Davis, we are determining the transcriptional networks regulating the vascular cambium and wood formation in the model forest tree genus, Populus (funded by USDA AFRI).
  • In collaboration with Luca Comai and Isabelle Henry at UC Davis, we are determining the mechanisms responsible for superior performance of Populus hybrids for bioenergy production. This research is funded by the joint DOE/USDA Plant Feedstock Genomics program, and will provide new genomic tools for poplar breeders to identify germplasm with unique genotypes and increased biomass yields, and develop techniques for creating poplar hybrids with unique combinations of chromosomal regions.
  • We are investigating methods for evolution and development (evo-devo) studies of wood formation in trees. Evo-devo studies could give important insights into the evolutionary origins and diversification of woody growth, and could ultimately provide new approaches for developing applications for bioenergy, carbon sequestration, and conservation.
Research Interest
I am working towards providing fundamental information about tree growth and development and the genetic and cell biology levels, with an emphasis on wood formation.

Research Highlights

Wood Biology Breakthrough

Year: 2016
Forest Service scientists determined how trees alter wood development to reorient stems in response to mechanical stress and gravity.

Gene-sequenced Poplars Potential Research Boon for Bioenergy

Year: 2016
A large population of poplar trees with altered gene dosage has been developed for bioenergy feedstock research. Each of the trees has been subjected to full genome sequencing, which identifies genetic variation, which is in turn correlated with specific traits pertinent to tree growth and biomass p...

Breakthroughs in Poplar Genomics Improve Bioenergy Feedstock Options

Year: 2014
Developing fast growing poplar cultivars for biofuels production is a major step towards renewable, tree-based energy. Optimal properties of short-rotation poplar cultivars grown for biofuels differ from previous timber-based cultivars, presenting a major challenge for tree breeders. Forest Service ...

Regulation of bark and wood growth in trees

Year: 2011
The dividing cells of the cambium meristem provide cells that differentiate in either wood or bark. Although fundamental to how trees grow, regulation of these processes is poorly understood. We identified and characterized specific genes that regulate where the cambium forms, and how the bark and w...

Historic Critchfield Memorial Herbarium Goes Digital: Believed to Be the Largest Collection of Pine Specimens in the World

Year: 2010
The USDA Forest Service's Pacific SouthwestResearch Station, Institute of Forest Genetics, Placerville, CA, has released the online version of its historic Critchfield Memorial Herbarium. The website includes collection information as well Memorial Herbarium. Note the collection has a photograph of ...
