Distribution and enrichment analysis of DEGs and DEPs (left and right panels, respectively) across different Cluster of Orthologous Group of proteins (COG) functional categories. The DEGs and DEPs were identified by transcriptomics and proteomics, respectively. Significant enrichment is indicated by a single asterisk (the P values less than 0.05 are labeled; two-sided Fisher’s exact test). All exact P values are provided in the data source file. COG functional categories: [C], Energy production and conversion; [D], Cell cycle control, cell division, chromosome partitioning; [E], Amino acid transport and metabolism; [F], Nucleotide transport and metabolism; [G], Carbohydrate transport and metabolism; [H], Coenzyme transport and metabolism; [I], Lipid transport and metabolism; [J], Translation, ribosomal structure and biogenesis; [K], Transcription; [L], Replication, recombination and repair; [M], Cell wall/membrane/envelope biogenesis; [O], Posttranslational modification, protein turnover, chaperones; [P], Inorganic ion transport and metabolism; [S], Function unknown; [T], Signal transduction mechanisms; [U], Intracellular secretion, trafficking, and vesicular transport; [V], Defense mechanisms.
