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 …

Strains of Soybean Mosaic Virus: Aphid Transmission, Host Passage Effects, and Use in Evaluation of Genetic Resistance in Soybeans
Seven soybean mosaic virus (SMV) strains proved to be aphid transmissible, however, one isolate of strain G5 lost its aphid transmissibility after about 30 successive passages by sap inoculation through a susceptible soybean cultivar Rampage during 20 months. The aphid nontransmissible strain G5 …

The nucleotide sequence of the 3' terminus of soybean mosaic virus
The nucleotide sequence of the 3' terminus of soybean mosaic virus (SMV) VA/G1 RNA has been determined by dideoxynucleotide sequencing of oligo(dT) primed cDNA cloned into a pUC19 cloning vector via EcoR1 linkers. One recombinant plasmid, pSMV49, identified by colony and dot-blot hybridization to …

Genetic resistance to and diversity of soybean mosaic virus
Four soybean (Glycine max (L.) Merrill) cultivars from China were studied to determine the inheritance of their 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 …

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 …

Inheritance of Resistance to Soybean Mosaic Virus in Soybeans and Studies on Seed Transmission
Five tropically adapted soybean (Glycine max (L.) Merrill) lines that varied in their reactions to inoculation with seven strains of soybean mosaic virus (SMV) were used in a study to determine the inheritance of resistance to SMV. F(,1), F(,2), and F(,3) populations were inoculated with SMV …

Identification, Validation, and Mapping of Phytophthora sojae and Soybean Mosaic Virus Resistance Genes in Soybean
… $43 billion annually, the cultivated soybean Glycine max (L.) Merr., is the second most valuable crop in the United States. Soybeans account for 57% of the world oil-seed production and are utilized as a protein source in products such as animal feed. The value of a soybean crop, …

Tracking soybean mosaic virus movement in soybean by leaf imprint immunoassay
The responses of soybean (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 …

Genome and Transcriptome Based Characterization of Low Phytate Soybean and Rsv3-Type Resistance to Soybean Mosaic Virus
Soybean is a dominant oilseed cultivated worldwide for its use in multiple sectors such as food and feed industries, animal husbandry, cosmetics and pharmaceutical sectors, and more recently, in production of biodiesel. Increasing demand of soybean, changing environmental conditions, and evolution …

Soybean Mosaic Virus Hc-Pro Enhances Viral Symptoms, Bean Pod Mottle Virus and Transgene RNA Stability, siRNA Accumulation, and Reduces Soybean Seed Production
The interactions between plant viruses and their hosts are constantly evolving. When plants produce a defense system against viral infection, viruses develop means to overcome this host response. Soybean [Glycine max (L.) Merr.] plants infected with Bean pod mottle virus (BPMV) alone develop acute …

The Effects of Temperature On The Durability Of Resistance Of Soybean To Soybean Mosaic Virus
… temperature sensitivity of alleles of Rsv1 in soybean (Glycine max (L.) Merr.). Soybean cultivars carrying alleles of Rsv were exposed to 1 several heat treatments designed to induce heat shock protein production prior to inoculation with soybean mosaic virus (SMV). The heat treatment methods …

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 …

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 …

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
<I>Bean pod mottle virus </I>(BPMV, Genus <I>Comovirus</I>, Family: <I>Comoviridae</I>)is an important virus in soybean (<I>Glycine max</I> (L.) Merrill), causing quality and yield loss due to seed coat mottling and seed weight reduction. Although BPMV has been known in Virginia since 1958 and has …

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 …

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 …
