Relationship between net charges of the propiece and mature peptide in avian and primate cathelicidins. a Separate linear regression lines were drawn for avian (y = −0.70x + 0.73; r = −0.38; p = 0.03) and primate CAMP (y = −0.32x − 0.18; r = −0.38; p = 0.02) genes. b Changes in the net charge of the propiece and mature peptide, as inferred to have occurred during evolution based on ancestral sequence reconstruction. Separate linear regression lines were drawn for avian (y = −0.42x + 0.17; r = −0.35; p = 0.01) and primate (y = −0.30x − 0.01; r = −0.36; p = 0.01) data points
