Figure 2. Sequence alignment between piscidins.

Multiple sequence alignments of the Nile tilapia piscidin peptides with selected piscidin or with other members of the piscidin family. Gaps were inserted to obtain maximum homology. Sequences used for comparison with the references for GenBank accession numbers are described in Supplementary Table 3. All gene sequences of the coding region were input into the dendogram for alignment. The same amino acid is indicated by the same color, such as methionine (M) being indicated by yellow.
