Poplar Biomass Interactome Project

(Project Personnel)

General overview

The development of whole-genome microarrays for Arabidopsis and poplar has led to the identification of hundreds of new wood-associated genes, which, in turn, has facilitated reverse genetics and in vitro experiments revealing protein-protein and protein-DNA interactions that dramatically influence wood formation. Such results illustrate the value of integrating transcriptomics with interactomics to identify regulatory networks important to the production of woody biomass. We are identifying protein-protein interactions relevant to genes expressed in wood-forming tissues of Populus trichocarpa.
