A cytogenetic map for the genomic studies of the West Nile Virus vector Culex tarsalis
Culex tarsalis is a major vector of West Nile Virus (WNV) in North America. Although the genome for this species was recently sequenced, the physical genome map has not developed. Unlike other Culex species, that have sex-determination locus on chromosome 1, the sex locus in Cx. tarsalis is located …

Development and Characterization of A Recombinant Orf Virus Vector Expressing the Spike Protein of Porcine Epidemic Diarrhea Virus
<p>Orf virus (ORFV), the type member of the genus <em>Parapoxvirus</em> of the family <em>Poxviridae</em>, causes orf or cutaneous pustular dermatitis in sheep and goats. ORFV is a ubiquitous virus capable of re-infecting its hosts multiple times over time. ORFV causes a non-systemic, self-limiting …

Engineering and use of plant viral expression vectors
Different plant virus-based expression systems were developed and compared using the colorectal cancer antibody CO17-1A and the corresponding antigen GA733-2 as model proteins. Tobacco mosaic virus (TMV) and alfalfa mosaic virus (AlMV) were used to construct the vector backbones of four systems to …

Persistent viruses in Capsicum annuum plants: Understanding the mystery guests
Most work on plant viruses focuses on their pathogenicity, but recent studies suggest viruses may benefit their hosts, at least under some conditions. Plant-infecting viruses of the Partitiviridae and Endornaviridae are transmitted only vertically, via pollen and seed, generally cause no disease …
