COG function classification and functional annotation of differentially expressed genes (DEGs). a COG function classification of DEGs on day 5. R5_vs_Y5 means gene set obtained by differential expression analysis on day 5, the upregulated (up) and downregulated (down) DEGs indicated that the expression level of the gene was significantly higher and lower (|Log2FC|> 1, FDR  < 0.05) on the 5th day of nitrogen deficiency (Y5) than that in the control group (R5), respectively. b Changes of the number of DEGs in TFs, TRs, and PKs. TFs means transcription factors; TRs means transcription regulators; PKs means protein kinases. TF_Up and TF_Down represent the upregulated and downregulated transcription factors, respectively, and so on
