Fig. 4.

Module-trait relationship heatmap for different traits and gene modules provided by weighted gene co-expression network analysis (WGCNA). The value in the box indicates the correlation coefficient between the module and the trait, followed by the corresponding p-value (in brackets). The boxes are colored based on the correlation of the module with the trait: red is a strong positive correlation, while blue is a strong negative correlation. The heat-tolerant cultivar (Topas) is highlighted in orange
