Identification and characterization of a DNA photolyase-containing baculovirus from Chrysodeixis chalcites.

A hitherto unknown single nucleocapsid nucleopolyhedrovirus (SNPV) with a unique property was isolated from larvae of the looper Chrysodeixis chalcites (Lepidoptera, Noctuidae, Plusiinae). Polyhedrin, lef-8, and pif-2 gene sequences were obtained by PCR with degenerate primers and used for phylogenetic analysis. ChchNPV belonged to class II NPVs and its polyhedrin sequence was most similar to that of class II NPVs of other members of the subfamily Plusiinae.
