Investigations into the viral molecular determinants of lethality of Punta Toro virus (Bunyaviridae, phlebovirus) in the Syrian hamster.
… reflect the absence of naturally occurring viral reassortants and in vitro reassortment experiments demonstrate segment segregation preferences amongst the RNA segments during replication and/or packaging. Viral reassortants were utilized to investigate the viral genome segment(s) responsible for …

Grapevine Fanleaf Virus: Biology, Biotechnology And Resistance
… depended on the identity of the GFLV strains or reassortants, on coapplication of heterologous silencing suppressors and on lower ambient temperatures. No natural sources of resistance to GFLV exist within Vitis spp., but certain herbaceous hosts such as N. tabacum (tobacco) are resistant. This …

Prevalence and Genetic Characterization of Avian Influenza Virus in Ring-billed and Franklin's Gulls in Minnesota
… FRGU H13N2, H13N6, and H13N8 AIV detected were reassortants with AIV genes of North American and Eurasian lineage primarily from other gull species but also commonly containing gene segments from North American duck species. The implications for not finding H5 AIV by rRT-PCR could mean that …

Matrix Gene Splicing and Emergence of Highly Pathogenic Avian Influenza
… viruses and for increased response times when reassortants or novel HPAI strains emerge in nature and threaten public health.

Virologic Factors Contributing to the Genetic Diversification of Influenza Viruses Circulating in North American Swine
… assessed the viral fitness of human HA and NA reassortants on both of the swine virus backbones. There were no observable differences with the human H3 and N2 on either of the swine backbones when compared to the parental swine backbones. However, we did see some viral fitness attenuation when …

Assessment of the Zoonotic Potential of a Novel Bovine Influenza Virus
… of the corresponding genes from ICV and viable reassortants were produced. It is unclear, however, the biologic impact of these reassortments. The answer to this and other aspects of our work will require a resolution to the current US Governments pause on gain-of-function research. This …

Reassortment of bluetongue virus vaccine serotypes in cattle
… cattle between BTV serotypes 11 and 17 where six reassortants with unique genetic profiles were described. In 2008, in Europe, segment 5 of BTV serotype 16 was identical to the South African vaccine strain of BTV serotype 2. In India in 2013 studies showed that in some isolates obtained from an …

Phylogenetic approaches for quantifying the genotypic diversity of influenza viruses
… prevalently facilitating the genesis of novel reassortants of pandemic concern, or whether there are similar internal genotypes circulating. There is therefore a need to characterize the observed and unobserved genotypic diversity of the internal genes of avian influenza viruses across the …
