While horizontal gene transfer (HGT) is well documented in bacteria, the role and frequency of HGT across eukaryotes remains poorly understood. Kominek et al. identified a horizontal operon transfer (HOT) event, with clear evidence for selection to facilitate gene expression, that has allowed a group of yeasts to scavenge iron using bacterially derived genes.
