GO enrichment in response to Al stress across three rice genotypes. Significantly, enriched GO categories in the up-regulated genes in tolerant genotype AR (a) and susceptible genotype IR (B) and TH (C) are shown. The genes were analyzed using BiNGO and the biological process terms showing significant enrichment are shown. Node size is proportional to the number of genes in each category and shades represent the significance level (yellow—no significant difference; red −>log2 fold upregulated; green − <log2 fold downregulated; scale, P = 005 to P < 00000005).
