Analysis of differentially expressed genes (DEGs) between ZX978 and ND476.
(A.) Heat map showing clustering analysis of DEGs between the two cultivars after drought stress treatment (SD_TD). (B.) Scatter plot showing the (log10 FPKM) expression of the DEGs in the SD_TD. (C.) Venn diagram showing the number of DEGs between SC_TC and SD_TD. Area III: 1305 DEGs only expressed in SD_TD.

GO enrichment of 13 important terms.
The “rich factor” shows the ratio of the number of the DEGs to the total gene number (Background number) in certain GO terms.
