Molecular Mapping Of A Soybean Mosaic Virus (SMV) Resistance Gene In Soybean (Glycine Max)
Soybean mosaic virus (SMV) is the major virus disease reported all over the world in soybean crop. This disease causes reduction in the yield and quality of soybean crop. Three independent genes Rsv1, Rsv3, and Rsv4, were found to provide host resistance in soybean. Rsv1 confers resistance to all …

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 …

Genetic analysis of soybean reactions to soybean mosaic virus
… mosaic disease, caused by soybean mosaic virus (SMV), is one of the most important soybean diseases in many areas of the world. This research, conducted in four separate studies, was designed to identify and characterize new sources of genes for resistance to SMV and to investigate the …

Assessing the Distribution and Impact of <I>Bean pod mottle virus</I> (BPMV) as a Re-emerging Virus, and <I>Soybean mosaic virus </I>(SMV) in Soybean Grown in Virginia
… studied, alone or with Soybean mosaic virus (SMV, Genus Potyvirus, Family Potyviridae) strain SMV G1, and isolates S98-51 and S98-52, on selected soybean cultivars. Individual isolates of BPMV showed variable symptom severity, and resulted in yield loss of between 40.4 to 58.1%, while SMV …

Tracking soybean mosaic virus movement in soybean by leaf imprint immunoassay
… 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 …

Genetics of reactions to soybean mosaic virus in soybean
… cultivars and 6 strains of soybean mosaic virus (SMV) were investigated. The objectives were to identify genes and/or alleles conditioning resistant and necrotic reactions to SMV and to determine the genetic relationships among resistance genes from cultivars exhibiting differential responses to …

Genetic resistance to and diversity of soybean mosaic virus
… resistant reactions to soybean mosaic virus (SMV) strain G1. Each of the cultivars was crossed with a susceptible cultivar Williams to determine the number of genes for resistance. The four cultivars were also crossed with lines with known genes for resistance to SMV to test for allelism. The …

Fine Mapping and Candidate Gene Discovery at the Rsv3 Locus
Soybean mosaic virus (SMV) is the most common member of the viral genus Potyvirus to infect soybeans (Glycine max [L.] Merr.) worldwide. SMV has been traditionally controlled by the deployment of single dominant, strain specific resistance genes, referred to as Rsv genes. Rsv1 is the most widely …

The Effects of Temperature On The Durability Of Resistance Of Soybean To Soybean Mosaic Virus
… prior to inoculation with soybean mosaic virus (SMV). The heat treatment methods were similar to those employed in the research with N gene-tobacco mosaic virus studies. The soybean cultivars used were Lee 69, York, Kwanggyo, Ogden and PI96983, carrying the Rsv, Rsv1-y, Rsv1-k, Rsv1-t, and Rsv1 …

High-Resolution Mapping of the Region around the Soybean Virus Resistance Genes, Rsv1 and Rpv1
Soybean mosaic virus (SMV) and peanut mottle virus (PMV) are potyviruses that can cause serious yield reductions in soybean [Glycine max (L.) Merr.]. Virus resistant soybean cultivars have been released with alleles at the Rsv1 and Rpv1 locus that confer resistance to SMV and PMV, respectively. A …

Strain differentiation and screening for resistance against isolates of soybean mosaic virus
… a method for the specific detection of the SMV G1 strain. The techniques were based on nucleotide sequence differences in that part of the SMV genome that spans the mid-region of the coat protein gene to the end of the non-coding region (NCR), and in the CI protein-coding region of the …

Characterization of the soybean genome in regions surrounding two loci for resistance to soybean mosaic virus
Soybean mosaic virus (SMV), has been the cause of numerous and often devastating disease epidemics, causing reduction in both the quality and quantity of soybeans worldwide. Two important genes for resistance to SMV are Rsv1 and Rsv4. Alleles at the Rsv1 locus have been shown to control resistance …

Role of virus genes in seed and aphid transmission and development of a virus-induced gene silencing system to study seed development in soybean
Soybean mosaic virus (SMV) and Tobacco streak virus (TSV) are two important seed transmitted virus that infect soybean. SMV is a member of the family Potyviridae genus Potyvirus, and is transmitted by seed and aphids in soybean. The symptoms of SMV infection on soybean typically include mosaic and …

The effect of varying mixtures of soybean and cereals on the landing rates of aphid vectors and spread of soybean mosaic virus (SMV) and maize dwarf mosaic virus (MDMV)
… plant viruses such as soybean mosaic virus (SMV) and maize dwarf mosaic virus (MDMV), and also on the landing rates of the aphid vectors that transmit them. The uniqueness of this study is that it gives an insight as to how the same aphids spread two foregut-borne non-persistently transmitted …

Soybean mosaic virus: strains, ultrastructure and movement
… The tolerant reaction of soybean to the 3 mild SMV strains was correlated with production of cytoplasmic strands. Soybean plants were most susceptible to G1/VA and peanut stunt virus (PSV) when the primary leaves were inoculated at 50-75% of their full expansion. Plants developed more severe …

Molecular Studies on Soybean Mosaic Virus-Soybean Interations
In the U.S., soybean mosaic virus (SMV) is classified into seven strain groups, designated G1 to G7, based on their different responses on resistant soybean [Glycine max (L.) Merr.] cultivars. These responses are: symptomless or resistant (R), necrotic (N), and mosaic or susceptible (S). The …
