KEGG annotations of differentially expressed genes. All differentially expressed genes in six comparisons (A: 3d vs. 0d; B: 30d vs. 0d; C: 60d vs. 0d; D: 30d vs. 3d; E: 60d vs. 3d; F: 60d vs. 30d) were annotated using the KEGG database for pathway analysis, and were classified according to the six KEGG subcategories ‘metabolism’, ‘GIP (genetic information processing)’, ‘EIP (environmental information processing)’, ‘CP (cellular processes)’, ‘OS (organismal systems)’ and ‘HD (human diseases)’.
