Abstract DNA photolyase genes (phr) encode photoreactive enzymes, which are involved in the repair of UV-damaged DNA. Cyclobutane pyrimidine dimer (CPD) specific photolyase genes are present in nucleopolyhedroviruses isolated from Chrysodeixis chalcites (ChchNPV) and Trichoplusia ni (TnSNPV) insects belonging to the Plusiinae subfamily (Noctuidae). To better understand the occurrence and evolution of these genes in baculoviruses, we investigated their possible conservation in other group II NPVs, which infect plusiine insects. A PCR based strategy using degenerate phr-specific primers was designed and validated to detect and analyze possible photolyase genes. Six additional Plusiinae-infecting NPVs were analyzed and all but one contained one or more phr-like sequences. Thysanoplusia orichalcea NPV A28-1 appeared to be a group I NPV, and did not contain a phr homologue. Phylogenetic analysis revealed that all photolyase genes of the tested Plusiinaeinfecting baculoviruses group in a single clade. Moreover, the phylogeny of the polyhedrin sequences of these viruses confirmed that the analyzed viruses also formed a single clade in group II NPVs. We hypothesize that all plusiine group II NPVs contain one or more photolyase genes and that these have a common ancestor. The correlation between baculoviruses having phr genes and the behaviour of their plusiine hosts will be discussed.
