(a) Overrepresented GO annotations for 472 differentially expressed genes (DEGs) in the fat body after 2 h of flight. The bar represents the proportion of the genes of one GO term in the DEGs (red) and all annotated genes (black). (b) Proportion of multi-copy (blue) and single-copy (green) genes for DEGs (right) and non-DEGs (left), respectively. (c) Expanded genes (red) involved in energy mobilization processes in the L. migratoria genome. PAT, perilipin; TAG, triacylglycerol; DAG, diacylglycerol; FA, fatty acid; ER, endoplasmic reticulum; FABP, fatty-acid-binding protein; Prdx6, 9 I cysteine peroxiredoxins; GST, glutathione S-transferase. (d) Gene copy number variation in energy-related metabolic pathways between two insect species, A. mellifera (AME) and D. melanogaster (DME), which primarily use glucose as an energy source during flight, and two insect species, D. plexippus (DPL) and L. migratoria (LMI), which primarily use fatty acids. ACAA2, acetyl-CoA acyltransferase 2; TCA, tricarboxylic acid cycle; CS, citrate synthase; ECHS1, enoyl-CoA hydratase; GAPDH, glyceraldehyde 3-phosphate dehydrogenase; IDH, isocitrate dehydrogenase; NDUFB9, NADH dehydrogenase (ubiquinone) 1β subcomplex 9; NDUFB4, NADH dehydrogenase (ubiquinone) 1β subcomplex 4; OXPHOS, Oxidative phosphorylation; NDUFS5, NADH dehydrogenase (ubiquinone) Fe-S protein 5; and QCR7, ubiquinol–cytochrome c reductase subunit 7.
