MapMan overview of nucleotide synthesis showing the purine pathway genes that are preferentially expressed in nodule compared to leaf tissue in common bean (A) and soybean (B). Individual genes are represented by small squares. The Log2(nodule/leaf) values for the differentially expressed genes (p < 0.0001, FDR < 0.0015, ≥ 2-fold difference) were false color coded using a scale of -3 to ± 3. The intensity of blue and red colors indicates the degree of preferential expression of the corresponding genes in nodule and leaf, respectively. Color saturates at ± 3 (8-fold difference or higher). See Methods for details. A complete list of the differentially expressed genes, corresponding MapMan functional categories, signal intensities and log ratios are provided in additional file 1 and 2.
