MapMan metabolism overview maps showing differences in transcript levels (0 versus 12 and 24 versus 36 HAI) during seed germination. A, 0 vs. 12 HAI. B, 24 vs. 36 HAI. Log2 ratios for average transcript abundance were based on three replicates of Affymetrix GeneChip® Wheat Genome Array. The resulting file was loaded into the MapMan Image Annotator module to generate the metabolism overview map. On the logarithmic color scale, blue represents downregulated transcripts, and red represents upregulated transcripts.
