a Hierarchical cluster tree revealing gene co-expression modules identified by WGCNA. The branches contain 15 modules labeled in different colors. Except the gray module, the modules are named ME1 to ME15. b Module-trait associations. Columns correspond to chlorophyll content, and rows correspond to the characteristic genes of the modules. The correlation between two is shown in cell by Pearson correlation coefficient, and p-value is in parentheses. Cell color ranges from red (high positive correlation) to blue (high negative correlation)
