Proteomics data summary (a) Principal component analysis (PCA) score plot of proteomic data. (b) On the upper right of the diagonal line of the image, the number indicates the correlation value of the two samples, * indicates the degree of significance (* p < 0.05, ** p < 0.01, *** p < 0.001); on the lower left of the diagonal line, the scatter plot of the expression values of the two samples is shown. The red curve is the fitting trend. The larger the slope, the stronger the correlation between the two samples; the diagonal line is the distribution graph of the sample’s own expression level. “S0d to S34d” refers to the type of samples (0d = baseline; 10 = retting samples for 10 days; 34d = retting samples for 34 days), the followed numbers refer to replicate samples
