STC-GO analysis. (A) The most significant gene expression tendencies of profiles 4, 7, 8, and 13 showed predominantly down-regulation patterns of gene expression. The horizontal axis represents stages, and the vertical axis shows the time series of gene expression levels for the gene after Log normalized transformation. The value in brackets after the profile represents the variation intensity, the genes assigned represent the gene number in each profile, the genes expected represent the theoretical gene number in each profile, and the p-value indicates significance. (B) The significant enriched GO terms in profiles 4, 7, 8, and 13.
