Soybean mosaic virus: strains, ultrastructure and movement
Two Virginia isolates of soybean mosaic virus (SHV), VA and OCM, were classified as G1 and G3 strains, respectively, according to a soybean differential cultivar system. G1/VA and G3/OCM differed in the symptom severity induced on soybean (Glycine max [L.]Merr.) plants and by the production by …

Soybean mosaic virus-soybean interactions: molecular, biochemical, physiological, and immunological analysis of resistance responses of soybean to soybean mosaic virus
… conditioned by a single dominant gene in soybean cv. York inoculated with SMV-G1, revealed no symptoms and no detectable viral replication (R). Unlike the hypersensitive response (HR), the R response did not result in localized virus and induction of a series of defense responses, but in …

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 …

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 …

Genetics of reactions to soybean mosaic virus in soybean
The genetic interactions among 9 soybean [<i>Glycine max</i> (L.) Merr.] 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 …

Genetic analysis of soybean reactions to soybean mosaic virus
The soybean [<i>Glycine max</i> (L.) Merr.] 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 …

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 Mosaic Virus Resistance in Soybean
… was conducted to analyze the genetics of soybean mosaic virus (SMV) resistance in soybean [Glycine max (L.) Merr.] and to determine allelic relationships of SMV resistance genes and their interactions with SMV strain groups. In the first part of this study, the inheritance of SMV …

Molecular genetic analysis of host resistance to soybean mosaic virus
Soybean mosaic virus (SMV), a potyvirus detected worldwide, can cause serious diseases in soybean (Glycine max L. Merr.). Host resistance to SMV conferred by a single dominant gene, Rsvl, was studied as a model to gain insights of plant virus resistance genes, and to facilitate the breeding of …

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 …

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 …

Characterization of soybean mosaic virus coat protein-mediated resistance in transgenic soybeans
<p>Soybean plants transformed with the coat protein (CP) gene from soybean mosaic virus, strain N, were obtained by using Agribacterium tumefaciens mediated transformation. Polymerase chain reaction and Southern blot analyses were used to detect the transgene. Four insertion events were detected in …

Strain differentiation and screening for resistance against isolates of soybean mosaic virus
The first part of this project attempted to develop 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 …

Mapping and Characterization of Phytophthora sojae and Soybean Mosaic Virus Resistance in Soybean
… the causal organism of stem and root rot, and <i>Soybean mosaic virus</i> (SMV) cause two of the most highly destructive diseases of soybean (<i>Glycine max</i> L. Merr). <i>P. sojae</i> can be managed either through deployment of race-specific resistance or through quantitative resistance termed …

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 …

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 …
