Gene duplication and structural diversity of AMPs in N. vitripennis. A. Gene duplication. Chromosome fragments are shown in lines and genes coding AMPs are represented by box, in which gray one stands for signal and pro-peptide and blue one indicates mature peptide. Introns are indicated in triangles with phase 1 in red, phase 2 in green, and phase 0 in cyan; B. Structural diversity in N. vitripennis AMPs. Changes in structure relative to classical insect defensins are circled.
