Phylogenetic relationship of all potential AMPs. A multiple sequence alignment of 606 potential AMPs was used to calculate a matrix with the genetic distances for each pair of the sequences. Based on this matrix, successive clustering of lineages was done to construct the unrooted phylogenetic tree of all potential AMPs gene using the maximum-likelihood algorithm with 1000 bootstrap replicates. Only branches supported by a bootstrap value of at least 50 % are indicated. Tree was generated using JalView [9]. The tree includes 606 sequences, and therefore only major nodes and global clusters are depicted. The labeling of the subfamilies is based on the location of AMPs that have experimentally confirmed function
