Functional GO enrichment analysis of the sets of DDEGs identified in the reference-based transcriptomic analysis. Top 10 enriched GO terms (Biological Process category) identified in the sets of up-regulated (red) and down-regulated (blue) DDEGs in (a) L-CN_vs_L-10, (b) S-CN_vs_S-10, (c) R-CN_vs_R-10, (d) L-CN_vs_L-20, (e) S-CN_vs_S-20, and (f) R-CN_vs_R-20. Only the top 10 (based on enrichment P-Value) enriched GO terms are plotted in function of their enrichment P-value (x axis) and number of genes (y axis). GO terms in sets of up-regulated and down-regulated genes are indicated in red and blue, respectively. Size key indicates the ratio of the number of genes in the test-set/total number of genes, for any given GO term. DDEG = Drought-responsive differentially expressed genes. The complete lists of enriched GO terms are presented in Supplementary Table S6.
