Evidence of a major role of GP64 in group I alphabaculovirus evolution

Virus Research, 2009
Previous investigations suggest that the divergence of the group I alphabaculoviruses was later than that of the group II alphabaculoviruses, however, there is no quantitative data to support this hypothesis. To examine this theory, the evolutionary rates of the 30 core genes that are conserved among all baculoviruses and the 11 unique genes among ...

An alphabaculovirus from the zebra caterpillar, Melanchra picta Harris, is an isolate of species Alphabaculovirus maconfiguratae

Journal of Invertebrate Pathology
A baculovirus had been previously identified in larvae of the zebra caterpillar, Melanchra (formerly Ceramica) picta Harris. To further characterize this virus, two isolates, Melanchra picta nucleopolyhedrovirus-185 (MepiNPV-185) and MepiNPV-600, were fully sequenced.

Morphological, genetic and biological characterisation of a novel alphabaculovirus isolated from Cryptophlebia peltastica (Lepidoptera: Tortricidae)

Journal of Invertebrate Pathology, 2018
Cryptophlebia peltastica is an agricultural pest of litchis and macadamias in South Africa with phytosanitary status for certain markets. Current control methods rely on chemical, cultural and classical biological control. However, a microbial control option has not been developed. An Alphabaculovirus from C.

A new Group II alphabaculovirus isolated from Spodoptera ornithogalli

2016
El gusano soldado de rayas amarillas es una polilla de la familia Noctuidae, común en Norte, Centro y Sudamérica, y en muchas islas del Caribe. Esta especie había sido reportada en muchos vegetales y otros cultivos incluyen sorgo, soja, remolacha azucarera y tabaco. Las larvas dañan las plantas principalmente por el consumo de follaje. S.

Mutations in the polyhedrin NLS affect the assembly and polyhedral shape of alphabaculovirus occlusion bodies

Biochemical and Biophysical Research Communications, 2022
Alphabaculoviruses produce occlusion bodies (OBs) in the nucleus of the infected cells at the late stage of infection. OBs are mainly composed of a single viral protein called polyhedrin (POLH). Autographa californica multiple nucleopolyhedrovirus (AcMNPV) POLH possesses a monopartite nuclear localization signal sequence (NLS), KRKK, from 32nd to 35th ...

Virus-host coevolutionary analyses of an Alphabaculovirus with a wide host range

Journal of General Virology
Baculoviruses are highly host specific, and their host range is usually restricted to a single or a few closely related insect species, except for few virus species, e.g. Alphabaculovirus aucalifonicae and Alphabaculovirus mabrassicae. In this study, two new alphabaculovirus isolates were isolated from the larvae of Mamestra brassicae and Mythimna ...

A betabaculovirus DNA polymerase cannot substitute for the DNA polymerase of the alphabaculovirus Autographa californica nucleopolyhedrovirus

Archives of Virology, 2017
DNA polymerase (DNApol) is present in all baculoviruses and plays a crucial role in viral DNA replication. Previously we showed that the DNApol of the alphabaculovirus group II Spodoptera litura nucleopolyhedrovirus (SpltNPV) could partially substitute for the DNApol of a group I alphabaculovirus, Autographa californica multiple nucleopolyhedrovirus ...

Evolutionary analysis and biological characterization of a novel alphabaculovirus isolated from Mythimna separata

Journal of General Virology
Baculoviruses are insect-specific pathogens. Novel baculovirus isolates provide new options for the biological control of pests. Therefore, research into the biological characteristics of newly isolated baculoviruses, including accurate classification and nomenclature, is important.
