Fig. 4From: The purplish bifurcate mussel Mytilisepta virgata gene expression atlas reveals a remarkable tissue functional specializationPanel (a) cumulative gene expression of the 1000 most expressed genes per tissue. The gene expression level on the Y axis is measured as TPM. Panel (b) Venn diagram displaying the overlap between highly expressed transcripts (TPMÂ >Â 100) among the five tissues subjected to RNA-seqBack to article page
