Pathways enriched in DEGs from two sorghum genotypes in response to sugarcane aphid herbivory. Pathways were compared among the 2-wk old resistant sorghum a, 2-wk old susceptible sorghum b, 6-wk old resistant sorghum c, and the 6-wk old susceptible sorghum (d) Pathways (FDR corrected p-value < 0.05) with significant numbers of up-regulated or down-regulated genes were identified by comparing gene expression in response to aphid herbivory and control (aphid-free plants). Color of the bars refers to the –log2 corrected p-value of the respective pathway. Red colored bars indicate enriched pathways in up-regulated genes, and blue colored bars indicate enriched pathways in down-regulated genes. The darker the red color the higher statistical significance. Length of the bar represents the number of genes within the respective GO term
