In particular we are interested in the proteins that are involved in the synthesis of DNA and also those that are responsible for the production of complete genomes. The specific aims are as follows: 1. Investigations on genome replication and processing. Our current evidence suggests that alkaline nuclease is involved in recombination-dependent replication and is required for the production of full length genomes. In addition, we have evidence that baculovirus DNA is partitioned in the infected cell into packaged and unpackaged DNA with the latter likely being involved in late gene transcription. We will continue these investigations as follows: a Recombination-dependent replication in another insect cell line.

Rohrmann, George F. Abstract This is the 4th edition of a book that was initiated with the annotation of the function of all the genes in the most commonly studied baculovirus, AcMNPV.
It has been almost six years since I reviewed this literature. As with the previous editions, this information is then integrated into chapters covering the major processes central to the replication and pathology of baculoviruses. Topics including taxonomy, the application of baculoviruses as insecticides, the molecular basis for the remarkable ability of these viruses to express genes at high levels, and the interrelationships of baculovirus and transposable elements are also covered.
The 4th edition includes 47 figures and 13 tables, all available for download. Some of the most extensive recent reports cover the reaction of cells during viral infection.
Whereas, the viral data is fairly straightforward because of the limited number of genes involved, the data from the host involves thousands of genes or their products. Therefore, although much data has become available, it is up to the researcher to find and interpret it in terms of their own specific interests. For much of the coming metagenomic and proteomic data, this appears to be our future.
Baculovirus molecular biology
Sajar One of the major methods that we use as a basis for characterization of the biochemical properties of proteins is to overexpress them in recombinant baculoviruses. The rabbit virus is a member of the herpesviridae and is a member of a primate lineage of these viruses. Transfer, incorporation, and substitution of envelope fusion proteins among members of the Baculoviridae, Orthomyxoviridae, and Metaviridae insect retrovirus families. Wei Sheng Wu Xue Bao. Baculovirus Molecular Biology — NCBI Bookshelf The establishment of solid bases to recognize their molscular relationships is necessary to facilitate the generation of new knowledge and the development of better methodologies.
Historical influence[ edit ] The earliest records of baculoviruses can be found in the literature from as early as the sixteenth century in reports of "wilting disease" infecting silkworm larvae. Since the s they have been employed to produce complex eukaryotic proteins in insect cell cultures see Sf21 , High Five cells. These recombinant proteins have been used in research and as vaccines in both human and veterinary medical treatments for example, the most widely used vaccine for prevention of H5N1 avian influenza in chickens was produced in a baculovirus expression vector. More recently it has been found that baculoviruses can transduce mammalian cells with a suitable promoter.
