Fig. 4From: Global transcriptome analysis of Huperzia serrata and identification of critical genes involved in the biosynthesis of huperzine AUnigenes expressed number and level on different tissues. a The number of expressed genes (FPKM ≥ 0.5) in each tissue was labeled over the bars. b Expressional levels of unigenes of all the tissues. c Venn diagram of expressed unigenes in four tissues. A total of 130,297 unigenes (71.9%) were expressed, of which 56,958 genes were common expressed in all four tissues. Unigenes with FPKM ≥ 0.5 were considered as expressed in each tissueBack to article page
