Bioinformatics analysis of the GFE vs. PFE groups

(a) Gene ontology annotation of the differentially regulated proteins based on cellular component, biological process and molecular function (GFE vs. PFE groups). The number above the bars represented the enrichment factor. (b) Biological process-based clustering analysis. (c) Cellular component-based clustering analysis. (d) Molecular function-based clustering analysis. DEPs were divided into Q1 (< 0.67), Q2 (0.67-1), Q3 (1-1.5) and Q4 (> 1.5) according to fold changes (GFE vs. PFE). The redder the color of the blocks, the more significant the enrichment. The greyer the color of the blocks, the lower the significant of enrichment
