Table I. GO enrichment analysis of maturation modules obtained from gene coexpression analysis.

Analysis was performed using AgriGO with the M. truncatula Affymetrix background applying a χ² statistical test method with the Yekutieli multitest adjustment method. The graphical view of the GO enrichment analysis for the FMD module is provided in Supplemental Figures S1 and S2. BG, Number of genes annotated in the GO term in background; FDR, false discovery rate; P, biological process; F, molecular function.
