Table 1 MapMAN pathway enrichment analysis of genes affected by MtPHD6 transgene or drought stress. DEGs (fold change ≥2 and P-value ≤0.05) were annotated using the Classification SuperViewer Tool. MapMAN was used as the classification source. The original data were presented in Additional file 5: Table S5.The scales of normalized frequency (NF) are as follows
