The effectors of the insect immune system are antimicrobial peptides. With the aim of studying the evolution of immune system genes, we identified a gene encoding the antimicrobial peptide defensin from a social insect, the wood ant Formica aquilonia. In this article we report the identification and characterization of this gene. We also compare the ant defensin gene structure to that previously obtained from two other hymenopteran species, the honeybee, Apis mellifera, and the bumblebee, Bombus ignitus. The ant defensin gene structure differs from both of these bee defensins with respect to the number and length of introns and exons.
