Gene co-expression modules and eQTL mapping. a Heat map of the correlations between the detected modules (M1 to M33) and stone cell, lignin, and cellulose contents. Numbers within the heatmap represent correlation coefficients (r values) and P values (in parentheses). The color scale at the right-top corner indicates module-trait r values. b GO enrichment analysis for M13, M14, M25, and M26. The top 10 enriched GO terms are shown. c Genomic distribution of eQTLs identified in stone cell formation modules in the pear fruit flesh. The x-axis indicates the physical positions of eQTLs, and the y-axis shows the physical positions of expressed genes. The gray lines separate the 17 pear chromosomes. The P value of each eQTL was analyzed using a Bonferroni test and is represented by three spot colors in the plot, red for the top 20%, blue for the bottom 20%, and gray for the rest
