Proteomics of Leaf Tissues from Populus

Abstract

Trees of the genus Populus are farmed commercially for wood and fiber, and are a potential bioenergy crop. As a scientific model organism, P. trichocarpa was the first forest tree for which the genome sequence has been determined. Knowledge of the Populus proteome will provide a deeper understanding of gene expression patterns in various tissues of the plant. To build on our previous profile of the proteome of xylem tissue in Populus (Kalluri et al., Proteomics 2009, 9, 4871), we are currently developing methods for studying the proteome of Populus leaves.
