Evolutionary analysis of the ubiquitin gene of baculovirus and insect hosts

S. S. Ma, Zhang, Z., Xia, H. C., Chen, L., Yang, Y. H., Yao, Q., and Chen, K. P., Evolutionary analysis of the ubiquitin gene of baculovirus and insect hosts, vol. 14, pp. 9963-9973, 2015.

Baculovirus is the only virus that has been found to encode the ubiquitin protein. In this study, ubiquitin sequences from 16 insects and 49 viruses were collected and compared. The resulting sequences were aligned with virus genomes. Then MAGE 5.0, k-estimated software, as well as other software programs were used for systemic evolutionary, selection pressure, and evolutionary distance analysis.

Bombyx mori pylorus infection by Alphabaculovirus

M. P. D. Baggio, Ribeiro, L. F. C., Vessaro-Silva, S. A., and Brancalhão, R. M. C., Bombyx mori pylorus infection by Alphabaculovirus, vol. 13, pp. 6332-6339, 2014.

Alphabaculovirus is an entomopathogenic virus genus that infects Bombyx mori, which is known as the Bombyx mori multiple nucleopolyedrovirus (BmMNPV). This virus is polyorganotrophic, and a series of tissues are known as targets; however, there is currently no information regarding infection in the pylorus, the segment of the hindgut that is present in the midgut transition and is responsible for food passage control. Thus, in the present study, we aimed to analyze infection of the B. mori pylorus by BmMNPV. To do so, hybrid B.

Cells of the rectum of Bombyx mori affected by experimental inoculation with Alphabaculovirus

S. A. Vessaro-Silva, Brancalhão, R. M. C., Baggio, M. P. D., and Ribeiro, L. F. C., Cells of the rectum of Bombyx mori affected by experimental inoculation with Alphabaculovirus, vol. 13, pp. 6885-6891, 2014.

Bombyx mori is an insect whose cocoon is used in the sericulture industry, which is an important activity in parts of southern Brazil. When parasitized by Bombyx mori nucleopolyhedrovirus (BmNPV) of the genus Alphabaculovirus (alphaBV), it develops nuclear polyhedrosis disease. In Brazil, an alphaBV was isolated from larvae of B. mori and various target tissues were identified. However, how this geographic viral isolate affects the rectum of silk moths was unknown.

Conserved baculoviral ORFs 10 and 14 from Bombyx mori multiple nucleopolyhedrovirus

S. A. Santos, Silva, J. L. C., Balani, V. A., Seixas, F. A. V., and Fernandez, M. A., Conserved baculoviral ORFs 10 and 14 from Bombyx mori multiple nucleopolyhedrovirus, vol. 9, pp. 457-470, 2010.

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.
