A new real-time PCR method using capturing oligo-immobilized PCR tubes is described. This method was used to detect specific genes for soybean and genetically modified (GM) soybean in food matrices. In a standard reaction using soybean genomic DNA and a capturing oligo for the lectin gene (Le1) immobilized on the tube, we examined the effects of such hybridization conditions as the location, le...

We estimated the economic benefits resulting from controlling soybean aphid infestation by using a multi-regional competitive dynamic equilibrium model. Results indicate that the reduction of soybean production resulting from a soybean aphid infestation is largely absorbed by reducing soybean exports, due to the higher price elasticity of export demand compared to domestic demand. Producer bene...

The standard fenoxycarb fire ant bait formulation (Logic), composed of pregel defatted corn grits and soybean oil toxicant, was modified by eliminating the soybean oil. This formulation without soybean oil contained greater than 2 times more fenoxycarb and was as effective as the standard bait formulation against laboratory colonies of red imported fire ant, Solenopsis invicta Buren. In field t...

Plant terpene synthase genes (TPSs) have roles in diverse biological processes. Here, we report the functional characterization of one member of the soybean TPS gene family, which was designated GmAFS. Recombinant GmAFS produced in Escherichia coli catalysed the formation of a sesquiterpene (E,E)-α-farnesene. GmAFS is closely related to (E,E)-α-farnesene synthase gene from apple, both phylogene...

Pearl millet and soybean flour were used in this study. Investigation showed that the major fraction of pearl millet protein was the prolamin followed by globulin and glutelin, while that of soybean was the globulin followed by glutelin and lesser amounts of albumin and prolamin. Cooking of pearl millet or soybean was found to decrease the globulin and true-prolamin fractions, while the prolami...

Soybean is a major ingredient in non-ruminant animal diets throughout the world. There is an extensive body of information suggesting that soybean is an excellent source of high quality protein, whereas less attention has been paid to soybean oligosaccharides. Soybean oligosaccharides, also referred to as ┙-galacto-oligosaccharides, oligosaccharides of the raffinose family or simply ┙-galactosi...

derrnatitis, we found 16 allergenic proteins in the soybean. i) About two-thirds of soybean-sensitive patients examined was shown to have IgE antibodies binding to the 30-kDa protein narned Gly m Bd 30K. This finding suggests that Gly m Bd 30K is a major allergen in the soybean and that it may be a target allergen for hypoallergenization of soybean products. Gly m Bd 30K has been purified to ho...

U.S. soybean producers have been cooperatively investing in both production research and demand promotion for nearly four decades to enhance the profitability and international competitiveness of their industry. Have producers benefitted from their contributions to soybean checkoff program activities over the years? How has the return to investments in soybean production research compared to th...

This study aimed at evaluating the response of the Normalized Difference Vegetation Index NDVI (MODIS sensor, TERRA satellite) of soybean to interannual variability of rainfall and evapotranspiration in Campos Gerais, a region of the state of Parana in southern Brazil. Landsat TM 5 and 7 images were selected for analyzing the spatial soybean field distribution for the region from 2000/01 to 200...

Glyphosate-resistant (GR) soybean [Glycine max (L.) Merr.] was developed by stable integration of a foreign gene that codes insensitive enzyme 5-enolpyruvylshikimate-3-phosphate synthase, an enzyme in the shikimate pathway, the target pathway of glyphosate. Application of glyphosate to GR soybean results in injury under certain conditions. It was hypothesized that if GR soybean is completely re...
