Fig. 5From: Comparative transcriptome analysis reveals key cadmium transport-related genes in roots of two pak choi (Brassica rapa L. ssp. chinensis) cultivarsHierarchical cluster analysis of transport-related genes expression profiles among four comparisons. The heat map represents cluster analysis of 135 differentially expressed unigenes. The log2 of readcount ratio for each unigene was used for hierarchical analysis in each of four comparisons: BCd10 vs. BCd0, KCd0 vs. KCd10, KCd0 vs. BCd0, and KCd10 vs. BCd10. Red and blue colors indicate up- and down-regulated unigenes in each comparison, respectively. The bar represents the scale of relative gene expressionBack to article page
