Fig. 3From: Full-length transcriptome sequencing reveals the low-temperature-tolerance mechanism of Medicago falcata rootsClustering analysis of the DEGs. a, Hierarchical clustering of the 11,369 DEGs on the basis of the averaged log2(FPKM+ 1) values of all genes in each cluster. b, The six subclusters of the 11,369 DEGs were clustered. The number of genes in each subcluster is shown at the top of the subcluster. The blue line shows the average values of the relative expression levels in each subcluster, and the gray lines represent the relative gene expression levels of each gene in each subclusterBack to article page
