Table 1 Selected modules from WGCNA and their correlation with heat stress (H) or control conditions (C). G represents the significant correlation (positive or negative) with the tolerant genotype (Topas); such a module also displays the opposite correlation with sensitive cultivar(s). Significantly enriched KEGG pathways [20] and corresponding adjusted p-values are indicated at each module
