TABLE 2.

The Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis of differentially expressed genes in spleen tissues on ED18 of incubation, LNV and DNV treatments, and day 7 post-hatch, LPHV, DPHV, LIV, and DIV treatments, that were exposed to green monochromatic light during incubation, were subjected to the DAVID database for pathway enrichment analysis.

Group	KEGG ID	Pathway terms	Fold enrichment	Entrez IDs of genes
LNV vs. DNV	gga00190 gga04620 gga03020	-Oxidative phosphorylation -Toll-like receptor signaling pathway -RNA polymerase	3.05 2.5 1.5	-PPA2, NDUFA5, NDUFS6, COX7C, UQCRFS1, NDUFB5 -NFKBIA, PIK3CG, TOLLIP, MAPK12, IRAK4 -POLR1D, POLR2F, POLR2D
LPHV vs. DPHV	gga01100 gga03320	-Metabolic pathways -PPAR signaling pathway	14.3 2.9	-PNLIPRP1, PSPH, ALDOB, SIIL, PLA2G1B, ATP5A1W, CEL, FUT9, ADH1C, GATM, TCIRG1, HPD, PLA2G1BL, AMY2A, UGT1A1 -SCD, APOC3, FABP1
LIV vs. DIV	gga01100	-Metabolic pathways	12.5	-PNLIPRP1, SIIL, PLA2G1B, CEL, PLA2G1BL, FUT9, AMY2A

All the pathways with a modified Fisher exact P-value < 0.05 and a threshold gene count of 2 were considered enriched.
