ABSTRACT. ORFs 10 and 14 from Bombyx mori multiple nucleopolyhedrovirus (BmMNPV) were amplified, cloned and sequenced. Nucleotide analysis of these genes and those of other baculoviruses showed that these genes are highly conserved. The p10 protein from BmMNPV ORF10 has 70 amino acid residues similar to that of the four other known BmNPV strains. The BmMNPV ORF14 alignment showed a higher identity with the nucleopolyhedrovirus ORF14 from the baculovirus BmNPV and from Autographa californica multiple nucleopolyhedrovirus. The BmMNPV ORF14 protein has a putative transmembrane domain in the C-terminal region, which is similar to that of other baculoviruses. A phylogenetic analysis showed that BmMNPV ORF14 protein has higher similarity with BmNPV ORF14 and ORF23 of A. californica multicapsid nucleopolyhedrovirus (Ac23). We conclude that proteins produced by ORFs 10 and 14 from BmNPV and BmMNPV are highly conserved in NPVs and MNPVs. The high degree of conservation among members of these genera indicates the importance of these proteins, which could mean an important function that is active throughout the infection cycle.

Baculoviruses are insect-specific viruses. These large DNA viruses encode many genes in addition to those required to replicate and build new virions. These auxiliary genes provide selective advantages to the virus for invading and infecting host insects. Eight of these genes, which help the virus overcome insect defenses against invasion, are discussed. These include genes whose products help the virus traverse physical or physiological barriers and those that overcome host immune defenses.

“…Among these genes, alk-exo was conserved in all baculovirus and fgf and was conserved in all lepidopteran baculoviruses [20]. Actin rearrangement-inducing factor-1 (arif-1) and ptp-1 was another two auxiliary genes, but absent in EupsNPV [26]. Homologous repeat sequences (hrs)…”

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.
