Module-trait relationships from the weighted gene co-expression network analysis. Module-phosphate treatment/scion/rootstock genotype correlation coefficients and corresponding p-values (in parenthesis) are given in each cell. The left panel shows the 26 modules and the number of module member genes. The colour scale on right shows module-trait correlation from −1 (blue) to 1 (red). HP: high phosphate, LP: low phosphate; PN: Vitis vinifera cv. Pinot noir; 1103P: V. rupestris x V. berlandieri cv. 1103 Paulsen (1103P)
