| molecular characterization of the major virion protein gene from the trichoplusia ni ascovirus. | ascoviruses (avs) belong to a family of double-stranded dna viruses that infect lepidoptera insects and cause the unique pathology of forming virion-containing vesicles in the hemolymph of infected hosts. virions of avs are large and contain more than 12 polypeptides. a gene, tnav-cp, encoding the major structural protein of the trichoplusia ni ascovirus 2a (tnav-2a) was cloned by immunoscreening an expression library with antibodies against total tnav virion proteins. tnav-cp is an intronless g ... | 2003 | 12913362 |
