Fig. 3From: Intracellular Ca2+ and K+ concentration in Brassica oleracea leaf induces differential expression of transporter and stress-related genesHierarchical cluster display of genes up- (n = 25) and down-regulated (n = 140) in Ca2+- and K+-dependent manner. The color scale bar at the bottom of the figure indicates the maximum log2 values of selected genes. See also Additional file 7: Figure S4 and Additional file 8: Table S4Back to article page
