Morphology and genome of Euproctis pseudoconspersa nucleopolyhedrovirus
Virus Genes 38 (3), 495-506
Abstract: Euproctis pseudoconspersa NPV (EupsNPV) is pathogenic to the tea tussock (E. pseudoconspersa), one of the major pests of tea bushes in East Asia, and has been used to control the pest. Electron microscope observation showed there were two modes for the virions embedded in each polyhedron, single-nucleocapsid and double-nucleocapsid. The EupsNPV genome contained 141,291 bp and had a G + C content of 40.4%. Of 139 potential ORFs predicted from the sequence, 126 had a homology in other baculoviruses; 13 were unique to EupsNPV. Four homologous repeat sequences (hrs) were present in the EupsNPV genome and the repeat sequences were different between these hrs. Three ORFs were identified to contain two homologues in the EupsNPV genome, including bro, p26 and dbp. Gene parity plots, percent identities of gene homologues and phylogenetic analysis all suggested that EupsNPV is most closely related to EcobNPV in Group II NPV, although its genomic organization was highly distinct.
