Figure 2:

Box-and-whisker plots showing relative expression of potassium channel genes in electric organ and skeletal muscle of Brienomyrus brachyistius. Many potassium channel genes were undetectable in the EO, this graph displays only those that were detectable. Note that Kcna7a is the predominantly expressed potassium channel in electric organ and Kcna7b is the predominantly expressed potassium channel in skeletal muscle. Accession numbers for all potassium channels utilized in this figure are listed in Table S5. See also Tables S1 and S2.
