Experiments were conducted using clonal trees under greenhouse conditions at the University of British Columbia. We used the 15.5K poplar cDNA microarray platform previously described by Ralph et al. (Molecular Ecology 2006, 15:1275-1297). Differentially expressed genes were determined using three criteria: fold-change between treated and untreated control leaves > 1.5-fold, P value < 0.05 and Q value < 0.05. This study identified > 3,000 differentially expressed genes in response to simulated insect feeding damage, which possess distinct source/sink and treated/systemic patterns.2009/06/03GSE16366GSM364136GSM364147GSM364165GSM364161GSM364162GSM364163GSM364164GSM364160592116366 PopulusPopulus trichocarpa x Populus deltoides
