Soybean meal is the most commonly used protein source in animal feeds. Among the undesirable attributes of soybean meal is the high level of β-mannan, which was determined to be detrimental to the growth performance of animals. β-Mannan is a type of hemicellulose in the plant cell wall and can be hydrolyzed by endo-β-mannanase. The goal of this study is to(More)
Soybean cyst nematode (SCN) is the most devastating pathogen of soybean. Information about the molecular basis of soybean-SCN interactions is needed to assist future development of effective management tools against this pathogen. Toward this end, soybean transcript abundance was measured using the Affymetrix Soybean Genome Array in a susceptible and a(More)
Salicylic acid plays a critical role in activating plant defence responses after pathogen attack. Salicylic acid methyltransferase (SAMT) modulates the level of salicylic acid by converting salicylic acid to methyl salicylate. Here, we report that a SAMT gene from soybean (GmSAMT1) plays a role in soybean defence against soybean cyst nematode (Heterodera(More)
and a decreasing supply (Golbitz, 1999), suggest that oil productivity of soybean should be improved. Previous Protein meal and oil are the two commodities produced from research indicated that seed oil concentration is con-soybean [Glycine max (L.) Merr.] that give the crop its value. Increasing seed concentrations of either or both may add value.(More)
Introduction Cultivar improvements in yield have allowed the soybean [Glycine max (L.) Merr.] to become the most important source of vegetable protein and oil in the world and the second most important crop in the U.S. In 2012, the estimated seed yield of soybean in the U.S. was 82 million metric tons harvested from 31.2 million hectares of land (Soy Stats,(More)
Soybean (Glycine max (L.) Merr.) salicylic acid methyl transferase (GmSAMT1) catalyses the conversion of salicylic acid to methyl salicylate. Prior results showed that when GmSAMT1 was overexpressed in transgenic soybean hairy roots, resistance is conferred against soybean cyst nematode (SCN), Heterodera glycines Ichinohe. In this study, we produced(More)
Project leader for the soybean breeding and genetics program. Basic and applied classical and molecular genetic research and development targeting genetically improved germplasm and new cultivars with enhanced productivity, disease resistance, herbicide tolerance, and tolerance to biotic and abiotic stresses. Development of lines with added value from(More)
This study explored the feasibility of near-infrared (NIR) quantitative and qualitative models for soybean inorganic phosphorus (Pi), which is complementary to phytic acid, a component of nutritional and environmental importance. Spectra, consisting of diffuse reflectance (1100-2500 nm) of ground meal and single-bean transmittance (600-1900 nm) of whole(More)
