“…So far, the TS gene has been reported in three insect viruses (Hz-1 virus, CIV and MsEPV) and two insect species ( D. melanogaster and B. mori ), yet differential relationships among them were detected. CIV was isolated from rice stem borer Chilo suppressalis ( Lepidoptera ) (Fukaya & Nasu, 1966), and can infect a number of herbivore insects that damage agricultural crops (Smith, 1976). MsEPV infects the North American migratory grasshopper Melanoplus sanguinipes as well as two related grasshopper species M. differentialitis and M. packardiibelongs , and the desert locust ( Locusta migratoria ) (Streett et al , 1990) and belongs to genus B of Entomopoxvirus subfamily that infects orthopterans and lepidopterans (Goodwin et al , 1991).…”

The sequence analysis of a thymidylate synthase gene was identified in the Hz-1 virus HindIII-D fragment. The viral thymidylate synthase gene encodes a protein of 295 amino acids, and is closely related to that of insect, mammals and herpesvirus. The thymidylate synthase gene identified was a genuine viral gene in that it was only detected in cells infected with Hz-1 virus but not in the mock infected cells, by Southern blot analysis and by RT-PCR. Results of phylogenetic analysis based on non-synonymous and amino acid distances suggested that the TS gene of Hz-1 virus was grouped closely with that of Bombyx mori. High bootstrap values confirmed that the thymidylate synthase of Hz-1 virus was acquired by a capture event from its lepidopteran host. Results of both sequence divergences and phylogenetic analysis suggested that TS genes in insect viruses, Hz-1, CIV, and MsEPV may have a different history or originated from different capture events.
