Construction and evaluation of infectious cDNA clones and analysis of packaging determinants of Soybean dwarf virus
Soybean dwarf virus (SbDV) is a phloem-limited, aphid-transmitted luteovirus that causes dwarfing of soybean plants. In the present study, infectious clones of two dwarfing isolates of SbDV were constructed, and methods for Agrobacterium-mediated inoculation of plants were standardized and used to …

The effect of irradiance on the activation state of ribulose bisphosphate carboxylase in soybean leaves
… (RuBP Case) activities was investigated in soybean (Glycine max cv. Will) leaves. Initial RuBP Case activity (IA), present in a leaf extract prepared at 0°C and assayed without prior activation, was used as an estimate of in vivo activity. Total activity (TA) was measured in leaf extracts …

Soybean Mosaic Virus Hc-Pro Enhances Viral Symptoms, Bean Pod Mottle Virus and Transgene RNA Stability, siRNA Accumulation, and Reduces Soybean Seed Production
… 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 symptoms that nearly disappear as …

Soybean and Phialophora gregata interactions: Implications for evaluating resistance to brown stem rot of soybean
Resistance of soybean to brown stem rot (BSR), caused by Phialophora gregata (Allington and Chamberlain) W. Gams, has become an important aspect of soybean breeding programs in the north central United States. The discovery of variability of P. gregata isolates from different states has increased …

3D machine vision system for robotic weeding and plant phenotyping
… system should be capable of differentiating crop plants and weeds to avoid contaminating crops with herbicide or damaging them with mechanical tools. For the plant genetics industry, automated high-throughput phenotyping technology is critical to profiling seedlings at a large scale to facilitate …

Inheritance of virulence in the root rot pathogen Phytophthora sojae
… Phytophthora sojae causes stem and root rot of soybean plants. The interaction of pathogen avirulence (Avr) and host resistance (R)-genes determine the disease outcome. The Avr3a mRNA transcript level is variable among P. sojae strains and determines virulence towards the R-gene Rps3a. To study …

Exploring the Genomic, Plant Growth Promoting, and Biocontrol Potential of a novum species 'Candidatus Pseudomonas auctus' JDE115 with its description
… and fluorescent bacterium isolated from soybean (Glycine max) root nodules in Virginia. Growth occurred at 0–5.0% NaCl (optimum 1%), pH 6.0–10.0 (optimum 7.0), and 10–40°C (optimum 28°C). Phylogenetic analysis based on the 16S rRNA gene and whole-genome sequencing placed JDE115 within the …

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 disease research on green stem disorder, effects of seed treatments on Sclerotinia stem rot, and resistance to Cercospora leaf blight
Soybean plants often exhibit varying delayed maturity symptoms at the end of the growing season. One delayed maturity malady known as green stem disorder (GSD) is the occurrence of non-senescent, fleshy green stems at harvest maturity with normal, fully mature pods and seeds. Data on GSD incidence …

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 …

Predator-prey interactions involving the soybean aphid (Hemiptera: Aphididae) in Missouri
The recently introduced soybean aphid, Aphis glycines Matsumura, is found in all soybean growing areas within Missouri. Despite soybean aphid's widespread distribution, it has reached economic threshold in few soybean fields in Missouri. We hypothesized that a predator complex suppresses soybean …

Enhancing Seed Quality and Application of Soybean through High Test Weigh and Low Trypsin Inhibitors
Soybean is an integral oilseed crop that is used all over the world. Despite this, soybean has been experiencing a decrease in seed quality seen by the decreasing trend in test weight, and is limited in its uses due to the antinutritional factor, trypsin inhibitor (TI). This project first worked to …
