Abstract The Israeli acute paralysis virus IAPV is a honeybee-infecting virus that was found to be associated with colony collapse disorder. The IAPV genome contains two genes encoding a structural and a nonstructural polyprotein. We applied a recently developed method for the estimation of selection in overlapping genes to detect purifying selection and hence functionality. We provide evolutionary evidence for the existence of a functional overlapping gene which is translated in the 1 reading frame of the structural polyprotein gene. Conserved orthologs of this putative gene which we provisionally call pog predicted overlapping gene were also found in the genomes of a monophyletic clade of dicistroviruses that includes IAPV acute bee paralysis virus Kashmir bee virus and Solenopsis invicta red imported fire ant virus 1. Background Colony collapse disorder CCD is a syndrome characterized by the mass disappearance of honeybees from hives 1 . CCD imperils a global resource estimated at approximately 200 billion 2 . For example it has been estimated that up to 35 of .
