Fig. 2From: Comprehensive dissection of transcript and metabolite shifts during seed germination and post-germination stages in poplarIdentification of unique stage-specific expression trends by K-means clustering. a Twenty-four clusters representing 10,148 genes with distinct stage-specific expression patterns. These clusters were further grouped into nine superclusters (SC1–SC9). The red dot in each cluster is the stage with the greatest combined fold-change of genes. b Enriched MapMan categories for each of the nine superclusters (SC1–SC9). Significant enrichment is indicated by a low p-value. Numbers in parentheses represent the number of genes included in each superfamily. c Distribution of transcription factors in each cluster. Genes that are expressed at only one stage are boxed in redBack to article page
