Abstract

A recombinant form of the nuclear polyhedrosis virus Autographa californica that does not produce an occlusion body in Trichoplusia ni insect larva can persist over several successive rounds of infection and has a multiplicity of infection of between 4 and 5 virus genomes per cell. The recombinant virus was co-occluded with the wild-type virus and used to infect fifth instar larvae.

Abstract

The gene coding for juvenile hormone esterase (jhe) was inserted into the genome of a Baculovirus containing a synthetic viral promoter. JHE was detected 12 hours after infection of Spondoptera frugiperda cells. Immunoblotting showed that the JHE produced was heterogenous, due probably to differential glycosylation. The recombinant gene was also expressed in vivo, however, no significant differences in weight, development or time of mortality was detected between larvae infected with jhe-expressing or -non-expressing virus.

Abstract

Research reveals that a genomic parasite in artificial nucleopolyhedrovirus cell cultures is maintained through cell propagation in insects. Results show that a few-polyhedra mutant of nucleopolyhedroviruses is able to persisit in equilibrium with the wild-type strain during serial rounds of infection.

25. LABORATORY STUDIES TO DETERMINE THE HIGH DOSE STATUS OF VIPCOT™ COTTON.

Author

O'Reilly, David R., Walters, Fred, Palekar, Narendra, Boyer, Ashley, and Kurtz, Ryan W.

Abstract

Syngenta is currently developing VipCot™, a transgenic insect-resistant cotton that expresses both Vip3A and Cry1Ab insecticidal proteins. These proteins were combined through the traditional breeding of two independent events, each expressing one of the two proteins. The mode-of-action of Vip3A is different from that of Cry1Ab, and there is no cross-resistance between these proteins. Therefore, from an Insect Resistance Management (IRM) perspective, a stack of Vip3A and Cry1Ab will represent an excellent and sustainable product for cotton lepidopteran pest control. We are currently evaluating the high dose status of VipCot™ to support the IRM strategy proposed for the product. In this paper, data from two laboratory-based methods assessing the high dose status of VipCot™ are presented. [ABSTRACT FROM AUTHOR]

Abstract

Syngenta is currently developing cotton varieties that express both Vip3A and Cry1Ab toxins. The mode-of-action of Vip3A is different to that of Cry1Ab, and there is no cross-resistance between Vip3A and Cry toxins, so that a stack of Vip3A and Cry1Ab will represent an excellent product from the Insect Resistance Management (IRM) perspective. We are currently evaluating the high dose status of the components of this stack to help formulate the IRM strategy that we will propose for the product. In this paper, laboratory and field data assessing the high dose status of candidate Cry1Ab components of the stack are presented. [ABSTRACT FROM AUTHOR]

42. Use of Baculovirus Expression Vectors.

Author

Walker, John M., Tuan, Rocky S., and O'Reilly, David R.

Abstract

The baculovirus expression vector system is a helper-independent system that has found extensive use in the past decade for the expression of heterologous genes. Its popularity stems from a combination of high levels of expression with the ability to carry out most eukaryotic posttranslational modifications in an authentic manner. As a consequence, the system has an excellent track record for the production of functional eukaryotic gene products. (See ref. 1 for a detailed recent review of the expression vector system and the basic biology that underlies it.) Baculoviruses are a large family of DNA viruses that have only been isolated from arthropods, with the majority found in insects. Autographa californica nuclear polyhedrosis virus (AcMNPV), the prototype baculovirus strain and the virus most commonly used in expression vector systems, infects a number of lepidopteran species. Like most baculoviruses, it has two distinct morphological types. The budded virus form comprises single virus particles surrounded by a lipid envelope, whereas the occluded virus form comprises multiple virus particles embedded in a matrix composed almost exclusively of a protein called polyhedrin. The bodies containing the occluded virus particles are known as occlusion bodies or polyhedral inclusion bodies. Up to 100 such occlusion bodies may form in the nucleus of an infected cell.

Abstract

A system is described for the rapid generation of Bombyx mori nucleopolyhedrovirus (BmNPV)-based expression vectors. A series of novel BmNPV genomes, that include a mini-F replicon and therefore can be maintained in Escherichia coli, have been generated. These genomes lack a portion of the essential ORF1629 gene and cannot replicate independently in insect cells. However, they can be used as parental genomes for the generation of expression vectors by cotransfection with a transfer plasmid that includes an intact ORF1629. Only recombinant viruses that have acquired the ORF1629 gene from the transfer vector, and have therefore also acquired the foreign gene of interest, can replicate after cotransfection. Parental genomes with and without a polyhedrin gene are described, enabling the generation of occlusion-positive and occlusion-negative recombinant viruses. Occlusion-positive expression vectors enable the oral infection of B. mori larvae and can therefore be used for the mass production of a foreign protein in infected insects. [ABSTRACT FROM AUTHOR]

47. Genetic Engineering of Helicoverpa armigeraSingle-Nucleocapsid Nucleopolyhedrovirus as an Improved Pesticide

Author

Chen, Xinwen, Sun, Xiulian, Hu, Zhihong, Li, Mei, O'Reilly, David R., Zuidema, Douwe, and Vlak, Just M.

Abstract

The Helicoverpa armigerasingle-nucleocapsid nucleopolyhedrovirus (HearNPV) has been registered and is commercially produced in China as a biopesticide to control the bollworm in cotton. However, the virus has a relatively slow speed of action. To improve its efficacy, recombinant HearNPVs were generated by deleting the ecdysteroid UDP-glucosyltransferase (egt) gene (HaCXW1 and HaLM2) or by inserting the insect-specific toxin gene AaIT in the egtlocus (HaCXW2) of HearNPV using conventional recombination strategies in insect cell culture. The various recombinants remained genetically stable when cultured in HzAM1 insect cells. Bioassay data showed a significant reduction in the time required for all HearNPV recombinants to kill second instar H. armigeralarvae. The LT50of the egtdeletion recombinants HaCXW1 and HaLM2 was about 27% faster than that of wild-type HearNPV. The largest reduction in LT50was achieved by inserting the gene for the insect-specific neurotoxin, AaIT, in the egtlocus, giving a reduction in LT50of 32% compared to wild-type HearNPV. The ability to genetically improve the properties of HearNPV as a biopesticide provides a further opportunity to develop this virus into a commercially viable product to control the bollworm in China.
