New genes from old: redeployment of dUTPase by herpesviruses.

abstract：:Some strains of the protozoan parasite genus Leishmania are persistently infected with single-segmented double-stranded RNA viruses, which are termed LRV. The function of these cytoplasmic viruses is unknown. In order to address the question of whether LRV affects the parasite's phenotype, pairs of isogenic LRV(+)-LRV...
