    Abstract Soybean [Glycine max (L.) Merr.] is important for the high protein meal used for livestock feed formulations. Carbohydrates contribute positively or negatively to the potential metabolizable energy in soybean meal. The positive carbohydrate present in soybean meal consists primarily of sucrose, whereas the negative carbohydrate components are the raffinose family of oligosaccharides (RFOs), raffinose and stachyose. Increasing sucrose and decreasing raffinose and stachyose are critical targets to improve soybean. In three recently characterized lines, variant alleles of the soybean raffinose synthase 2 (RS2) gene were associated with increased sucrose and decreased RFOs. The objective of this research was to compare the environmental stability of seed carbohydrates in soybean lines containing wild-type or variant alleles of RS2 utilizing a field location study and a date of planting study. The results define the carbohydrate variation in distinct regional and temporal environments using soybean lines with different alleles of the RS2 gene.

    Abstract Soybean is the preferred protein source for both poultry and swine feed. However, this preferred status is being challenged due to competition from alternative feed ingredients. To overcome this, it becomes necessary for breeders to develop soybean cultivars that contain higher protein and better nutritional composition. In this study, we have developed experimental soybean lines that not only contain significantly higher amounts of protein but also improved sulfur amino acid content. This objective was achieved by crossing a O-acetylserine sulfhydrylase (OASS) overexpressing transgenic soybean line with elevated levels of sulfur amino acid content (CS) with a high protein Korean soybean cultivar (Lee 5). Introgression of high protein and overexpression of OASS was monitored in the experimental lines at each successive generation (F2-F6) by measuring protein content and OASS activity. The average protein content of transgenic CS and Lee 5 seeds were 34.8 % and 44.7 %, while in the experimental soybean lines the protein content ranged from 41.3 %–47.7 %, respectively. HPLC and inductively coupled plasma-mass spectrometry analyses revealed that all the experimental lines developed in this study contained significantly higher amounts of sulfur containing amino acids and elemental sulfur in the seeds. The sulfur amino acid (cysteine + methionine) content of the experimental lines ranged from 1.1 % to 1.26 % while the parents Lee 5 and CS had 0.79 % and 1.1 %, respectively. SDS-PAGE and western blot analysis demonstrated that the accumulation of Bowman-Birk protease inhibitor and lunasin, two sulfur amino acid rich peptides, were elevated in experimental soybean lines. High-resolution 2D-gel electrophoresis and Delta2D gel analysis validated that an overall increase in the different subunits of 7S β-conglycinin and 11S glycinin were mainly responsible for the observed increase in the total amount of protein in experimental lines.

    Abstract Corn (Zea mays) stover is an attractive choice for cellulosic ethanol production because it is readily available and easily obtainable. Understanding how corn stover removal affects soybean (Glycine max) emergence and yield is essential to developing appropriate management recommendations for both crops in a corn–soybean rotation. The objectives of this study were to determine (i) the effects of corn stover removal on soybean emergence and yield and (ii) if cover crops ameliorate any of the possible negative effects to soybean from corn stover removal. Removing stover allowed soil temperature to increase, slightly, but cover crops had little or no effect. Stover removal and cover crops had no effect on three soybean emergence parameters except stover removal resulted in a more nearly uniform stand in 1 yr. Soybean stand density increased with stover removal. Soybean grain yield was not affected by either stover removal or the use of cover crops. Removing corn stover may have long term effects on important soil characteristics and these may impact future grain-crop productivity.

    Abstract Soybean [ (L.) Merr.] contains several health promoting compounds including phytosterols, isoflavones, phytic acid, and protease inhibitors. The two abundant protease inhibitors of soybean seeds are the Kunitz trypsin inhibitor and the Bowman-Birk inhibitor (BBI). Bowman-Birk inhibitor has been touted as a potential cancer chemopreventive agent for humans. Little information is available on the effect of growing location on the accumulation of this cancer chemopreventive agent. In this study we have examined the protein profile of eight soybean varieties that were grown in three Missouri locations in 2009 and 2010. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) analysis demonstrated that soybean varieties that were grown in Grand Pass contained elevated levels of the subunit of -conglycinin and reduced amounts of BBI. This observation was further confirmed by Western blot analysis. This difference in the levels of BBI was also reflected in the chymotrypsin inhibitor activity. Growing location also influenced the overall S content of soybean seeds as evidenced by inductively coupled plasma mass spectrometry analysis. Seeds grown in Grand Pass had lower amounts of total S content in both 2009 and 2010. Our results demonstrate that growing location has a profound effect on the accumulation of BBI and it is possible to modulate the concentration of this cancer chemopreventive agent by simple changes in agronomic practices.
