Tracking soybean mosaic virus movement in soybean by leaf imprint immunoassay
… (Glycine max (L.) Merr.) to soybean mosaic virus (SMV) include mosaic, necrosis and no symptoms, and vary with virus strain and allele of the gene for resistance (Rsv) carried by the host. Genetic studies have shown that plants giving mosaic are susceptible, and that plants giving either the …

Biochemical and histological investigations of viral localisation in the hypersensitive reaction of Phaselous vulgaris L. var Pinto to tobacco mosaic virus infection
… vulgaris L. var Pinto to tobacco mosaic virus infection. The infection of Phaseolus vulgaris L. var Pinto with tobacco mosaic virus (TMV) results in the production of distinct necrotic lesions confining the virus to restricted areas of the leaf surface. Biochemical and histological …

Cellular Functions of the Squash Leaf Curl Geminivirus Movement Proteins BL1 and BR1
Plant viruses encode what are typically called movement proteins (MPs). These are defined as proteins dispensable for viral replication and encapsidation, but essential for cell to cell movement of the virus to the phloem and eventually leading to systemic infection of the plant. Unlike most plant …

Host-parasite interactions of barley yellow dwarf virus and oats: Physiological and immunological studies
… stresses. The pathogen, barley yellow dwarf virus (BYDV) is restricted in its host to phloem tissue, and phloem blockage leads to the accumulation of photosynthate in the foliage. Diagnosis of the disease usually entails virus detection with strain-specific antibodies. Fourteen virus-specific …

<i>Maize fine streak virus</i> (MFSV) gene expression and protein interaction
<i>Maize fine streak virus</i> (MFSV) belongs to the family Rhabdoviridae, and is transmitted by the leafhopper <i>Graminella nigrifrons</i>. The MFSV genome is a 13,782 nucleotide, non-segmented, negative-sense RNA that encodes five core structural proteins: the nucleocapsid protein (N), the …

Virus-host interactions in the cassava brown streak disease pathosystem
The research seeks to understand the virus-host plant interactions for cassava brown streak disease (CBSD) caused by two viruses, Cassava brown streak virus (CBSV) and Ugandan Cassava brown streak virus (UCBSV) of the genus Ipomovirus, family Potyviridae. The diversity of six CBSD isolates from the …

Interactions of soybean Rsv genes and Soybean mosaic virus
Soybean mosaic virus (SMV; Genus Potyvirus; Family Potyviridae) is one of the most widespread viruses in soybean (Glycine max [L.] Merr.). Hutcheson, a cultivar developed in Virginia, is resistant to the common strains of SMV. However, new resistance-breaking (RB) isolates of SMV have emerged in …

Controlling Tobacco Mosaic Virus in Tobacco through Resistance
Tobacco mosaic virus (TMV) infects all classes of tobacco (Nicotiana tabacum L.) and causes losses worldwide. The N gene is the most effective means of controlling TMV; however, this gene is associated with reduced yield and quality in flue-cured tobacco. The mode of inheritance of TMV resistance …

Studies on improvement of Chinese wheat cultivars for resistance against an endemic virus using transgenesis and virus-wheat interactions at the molecular and ultrastructural levels
… for resistance to Soil-borne wheat mosaic virus (SBWMV) by transgenesis, and an examination of virus movement by studying the complementation of movement proteins (MPs) from Tobacco mosaic virus (TMV) and SBWMV using a TMV-based virus vector.<br/><br/>A number of SBWMV coding sequences, …

Prevalence and Genetic Characterization of Avian Influenza Virus in Ring-billed and Franklin's Gulls in Minnesota
The natural reservoirs for avian influenza virus (AIV) are wild waterbirds such as ducks and gulls. In Minnesota, gulls are abundant and known to visit poultry farms, yet are underrepresented in AIV wild bird surveillance efforts. The purpose of this research was to fill part of this surveillance …

Genomic and genetic resource for soybean disease resistance improvement
… and abiotic stress resistance. Soybean mosaic virus (SMV) causes significant reductions in soybean yield and seed quality. In North America, seedborne infections are the primary sources of inoculum for SMV infections. Therefore, host-plant resistance to SMV seed transmission provides a means to …
