Fig. 4From: Comparative transcriptome analysis and identification of candidate R2R3-MYB genes involved in anthraquinone biosynthesis in Rheum palmatum L.Comparison of the transcriptomes of the CK and MeJA treatment groups of R. palmatum. A The PCA analysis of unigenes based on the expression levels in the CK and MeJA treatment groups; each treatment was performed in three replicates. B The volcano plot of DEGs between the CK and MeJA treatment groups. C The statistical analysis of DEGs between the CK and MeJA treatment groups. D KEGG enrichment analysis of DEGs between the CK and MeJA treatment groups. E The heatmap of differentially abundant MYBs and key enzyme unigenes in the anthraquinone biosynthesis pathway in R. palmatumBack to article page
