The main expression patterns of 2,646 transcripts analyzed by model profile and the two significant patterns (profile No. 2 and No. 76). A, Each box represents a model expression profile. The upper number in the profile box is the model profile number, and the lower one is the p-value used to summarize the different gene expression patterns. In total, 22 expression patterns of genes showed significant p-values (p < 0.05). The same color represents the same group. The model profiles marked with red (group I) represent the upregulated expression patterns, whereas the green profile boxes (group II) represent the downregulated expression patterns. Profile No. 55 and 58 (group III) belong to the pattern that was upregulated first then downregulated, whereas the remaining profile boxes (group IV) belong to the opposite pattern with group III. B, Profile No. 2 increased in expression and profile No. 76 decreased in expression during seed germination. The horizontal axis represents the germination phase, and the vertical axis shows the time series of gene expression levels for the gene after Log2 normalized transformation.
