KEGG pathways enrichment of DEPs
KEGG analysis was used to identify the significant functional pathways
enriched with differentially expressed proteins. Of the DEPs we obtained
9 significant KEGG pathways (FDR < 0.1; Table 1). These DEPs
were mainly classified into oocyte meiosis, nucleotide excision repair,
ErbB signaling pathway, gap junction, GnRH signaling pathway, vascular
smooth muscle contraction, RNA transport, protein processing in
endoplasmic reticulum (FDR < 0.05), and other pathways related
to metabolic processes (FDR < 0.1). Among all the DEPs, the
GnRH signaling pathway, and the protein processing pathway were most
strongly related to the known difference in seasonal reproductive timing
in resident and migrant juncos.
