POPCAN – Characterization of cuticular waxes in Populus leaves

Research Interests

Plants respond to multiple abiotic and biotic stresses with an intricate chemical language of specialized metabolites (also known as secondary metabolites) that are constantly evolving. My primary interest is to use an integrative approach to understand this biochemical response by exploring how new chemicals are produced, deciphering their ultimate biological function, and understanding how the choice of metabolites depends on the abiotic and biotic environment.

My current project in the laboratory of Dr. Shawn Mansfield is part of a large-scale multidisciplinary genomics project (POPCAN) that is exploring diversity in Populus trichocarpa (black cottonwood) natural populations to facilitate genetic improvement of the species as a bioenergy feedstock. As part of it, I have been studying the natural diversity in P. trichocarpa cuticular waxes. Cuticular waxes are composed of a mixture of lipids that coat the plant surface, and as such they constitute the first barrier against a hostile environment. To assess wax diversity, I examined the variation in composition and abundance among genotypes and developmental stages using gas chromatography (GC) and mass spectrometry (MS). This approach has produced a large metabolite dataset that is being mined in combination with genome and transcriptome data to uncover the genes involved in the biosynthesis and regulation of wax components.
