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 …

Rheological Properties of Soybean and Soybean-Solute Systems
… the young. Concentrated intermediate moisture soybean beverages, if successfully developed, would represent a partial solution to both the above problems.

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 …

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 …

Effects of selective genetic introgression from wild soybean to soybean
Commercial soybean [Glycine max (L.) Merr.] breeding in the U.S. currently relies on a narrow genetic base in which more than half of the genetic contribution, calculated by pedigree analysis, comes from only 5 ancestral lines. For decades, but more intensely in recent years, efforts have been made …

Dynamics of soybean leaf hydraulic conductance and diurnal soybean transcriptome analysis
… both short and long time scales, the capacity of soybean Kleaf to acclimate to environmental conditions is of interest, particularly with regard to potential hydraulic limitations to photosynthesis. This dissertation research examines the acclimation responses of soybean Kleaf to climate change …

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 …

Diaporthe, Soybean Cyst Nematode, and Soybean Aphid: An Evaluation of Potential Interactions Occurring Among Pests on Soybean in South Dakota
<p>Soybean <em>Glycine max</em> (L.) Merr., is an important crop grown in South Dakota, with an estimated production of $2.33 billion in 2015. However, soybean production in South Dakota is compromised by four pests, the fungal pathogens <em>Diaporthe longicolla</em> (Hobbs) Santos, Vrandecic, and …

Pseudomonas spp. Isolated from Soybean Nodules Promote Soybean Growth and Nitrogen Fixation
Nitrogen-fixing bacteria in soybean nodules convert atmospheric nitrogen to plant-available forms in exchange for carbon from the plant, but other non-nitrogen-fixing bacteria also reside in nodules, and their role in the nodule is not well understood. This study was conducted to determine the …

Evaluation and Identification of Soybean Aphid Resistance Sources and Mapping of Soybean Aphid Resistance Loci in Early Maturing Soybean Germplasm Accessions
<p>Soybean aphid (Aphis glycines Matsumura) has been a major pest of soybean [Glycine max (L.) Merr.] in North America particularly in the northern United States and three Canadian provinces. At least four biotypes of soybean aphid have been confirmed in the United States. Identification of soybean …

Molecular Approaches to Facilitate Marker-Assisted Selection for Soybean Aphid Resistance in Soybean
… including yield in two elite Midwest adapted soybean backgrounds. This study was done because sometimes the introgression of resistance genes from nonadapted sources can carry undesirable genes through genetic linkages. To test for associated effects, field evaluations of two backcross …

Evaluation of soybean aphid resistance, yield qtl confirmation, and genetic gain in soybean
Soybean Aphid Resistance in Exotic Soybean Lines The soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), is a common insect pest of soybean [Glycine max (L.) Merr] in China and is also found frequently in other Asian countries. It was identified in the US in 2000 and has since spread …

Whole genomic structural variant calling in soybean: Analysis on 481 different soybean lines
Soybean (Glycine max) is an important crop worldwide, with utilities as protein source and rotation crop. Often, soybean variant discovery is conducted using alignment methods and largely yields short variants such as SNP(s) and short indel(s). We conducted variant discovery on 481 soybean lines …

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 …

SPECTROSCOPIC CHARACTERIZATIONS OF THE COMPOUND II INTERMEDIATE OF SOYBEAN PEROXIDASE FROM SOYBEAN SEED COATINGS
Spectroscopic characterization of ferric soybean peroxidase with peroxides were studied to determine the ligand coordination and to characterize the structure of the heme active site and its intermediates (ferryl species). The lifetime, chemical reactivity and distinctive colors of the ferryl …
