Numbers of DEPs in Korla fragrant pear fruits at three developmental stages. A, A clustering heat map of the three developmental stages of Korla pear fruit, indicating the differences and reproducibility among different developmental periods. B, The number of up- and downregulated differentially expressed proteins in three pairwise comparison groups, with the horizontal axis representing the comparison groups and the vertical axis representing the number of differentially expressed proteins. C, D, and E represent the volcano plots for 10 WAF vs. 5 WAF, 15 WAF vs. 5 WAF, and 15 WAF vs. 10 WAF, respectively. The horizontal axis is log2(FC), with values farther from 0 indicating greater differences, with the right side representing upregulation and the left side representing downregulation. The vertical axis is -log10(P value), with values farther from 0 indicating greater significance. Blue dots in the plot represent downregulated differentially expressed proteins, red dots represent upregulated differentially expressed proteins, and gray dots represent non-significant differentially expressed proteins. F, The Venn diagram analysis of differentially expressed proteins in the 10 WAF vs. 5 WAF, 15 WAF vs. 5 WAF, and 15 WAF vs. 10 WAF comparison groups.
