Figure 4From: Nitrogen-driven stem elongation in poplar is linked with wood modification and gene clusters for stress, photosynthesis and cell wall formationSignificantly enriched and depleted MapMan categories in the main complexes of an N-responsive gene network in the elongation zone of P . trichocarpa. Genes identified in main complexes of the N-responsive network of the poplar elongation zone were assigned to the best Arabidopsis matches (AGI numbers) using Poparray (http://aspendb.uga.edu/poparray) and categorized with Superviewer. Data are means ± SD for 100 bootstraps of the initial data set. Stars indicate: *p < 0.05, **p < 0.01, ***p < 0.001.Back to article page
