Phylogenetic evidence is provided for horizontal transfer of a natterin-like toxin encoding gene from fungi into the genome of the coral Acropora digitifera.  Sequencing analysis of the coral tissues supported that a fungal taxon predicted to be the most likely gene donor was represented in the coral microbiome. Further bioinformatics data suggested widespread recruitment of the natterin-like gene into venomous terrestrial invertebrates, and repositioning of this gene to non-toxic functions in non-venomous teleost fish.
