Fig. 7From: Primary root response to combined drought and heat stress is regulated via salicylic acid metabolism in maizeWeighted gene coexpression network analysis of the active genes (FPKM > 1). A Hierarchical clustering tree (cluster dendrogram) showing 31 modules of coexpressed genes according to their expression patterns. B Correlations between each module and organic acids. Pearson correlation coefficient and e-value of the module which had significant correlation with metabolites were shown in the figure. Red indicated positive correlation between modules and metabolites, blue indicated negative correlationBack to article page
