The WGCNA analysis revealed the correlation between DEGs and physiological traits related to drought stress regulated by melatonin. A The heatmap clearly shows the correlation between gene expression modules and physiological traits related to drought stress regulated by melatonin. B A module classification tree was constructed through hierarchical clustering analysis of WGCNA, demonstrating the similarity and difference between gene expression modules. C In the MEblue module, a detailed co-expression network of DEGs is depicted. D In the MEgreen module, a detailed co-expression network of DEGs is depicted. E In the MEblack module, a detailed co-expression network of DEGs is depicted. F In the Meyellow module, a detailed co-expression network of DEGs is depicted
