Fig. 1From: Comparative analysis of powdery mildew resistant and susceptible cultivated cucumber (Cucumis sativus L.) varieties to reveal the metabolic responses to Sphaerotheca fuliginea infectionAnalysis of the differentially expressed genes (DEGs) under S. fuliginea infection. a Heatmap for cluster analysis of the differentially expressed genes by K-mean method. Red indicated high expressed genes and green indicated low expressed genes. The heatmap scale ranges from − 2 to + 2 on a log2 scale. b MeV cluster analysis of the DEGs from the gene expression profiles. c The number of up- and down-regulated genes in different comparisonsBack to article page
