To assess the metabolic changes in Populus in response to pathogen stress, Accepted 6 August 2015 Populus stems infected or not with Dothiorella gregaria were analyzed by GCeMS. A total of 4, 051 fea- Available online 18 August 2015 tures were detected and 44 metabolites were identified to be changed significantly in Populus upon infection. The identified responsive metabolites include saccharides, alcohols, organic acids, and amino Keywords: acids and some secondary metabolites and most of the metabolites were detected at increased levels.
