Book Description
Soybeans (Glycine max (L.) Merr.) are the most important crop that provides a sustainable source of oil and protein worldwide. Five major fatty acids are known, Palmetic, Stearic, Oleic, Linoleic and Linolenic acid, and each is essential for both nutrition and biodiesel. Oil demand for biodiesel production is constantly on the rise both because of high crude oil prices and because of the search for a sustainable fuel source. In biodiesel production a high level of Oleic Acid is ideal. Commodity soybean oil usually contains around 20% oleic acid. The objective of this research is to increase the Oleic acid content to increase the quantity of biodiesel that can be produced from one bushel of soybeans. With the process of chemical mutagenesis using Ethyl Methanesulfonate (EMS), soybean populations can be produced with varying fatty acid levels. Once these populations are isolated and tested they can be bred into a new cultivar with higher percentages of Oleic acid and grown on a large scale for biodiesel production. From the ‘Forrest’ cultivar that was used in the chemical mutagenesis process, there was one mutant line (FM3 2014-2031) that produced 43.26% Oleic Acid. This was almost twice the concentration of the Forrest wild type that was used as a control which had an Oleic Acid concentration of 23.17%.

Book Description
Soybeans are among seeds the common plant foods that contains high protein contents and high oil. The protein provides about 35 to 38 percent of the seeds calories compared to around 20 to 30 percent in other legumes and many animal products. The quality of soy protein is notable and approaches the quality of meat and milk. Unlike many other good sources of protein, soybeans are low in saturated fat and are cholesterol-free. Its proteins provide all the important amino acids, most the amounts needed by humans (NSRL, 2010). As the most consumed vegetable oil in the world, soybean oil has been used substantially in the food industry (Soystats, 2010). Its utilization is determined by its fatty acid composition, with commodity soybean oil typically 13% palmatic acid (16:0), 4% stearic acid (18:0), 20% oleic acid (18:1), 55% linoleic acid (18:2), and 8% linolenic acid (18:3). The change of fatty acid profiles to improve soybean oil quality has been a long time goal of many researchers throughout the world. Biodiesel is an up and coming trend in energy production. Breeding effort can be undertaken in order to produce a higher energy profile soybean oil. Using ethyl-methanesulfonate (EMS) mutagenesis effects on DNA, significant changes to the genes and gene network underlying the protein and oil profile can be achieved. These changes are hard to accomplish using standard breeding techniques. In addition, high amount of linolenic and stearic acid are very important for fuel and biodiesel production, but are not good for food production due to the fact that such oil is oxidized easily and the food goes rancid quickly. However, soybean oil with elevated amount of oleic acid is desirable for food, because this monounsaturated fatty acid improves the nutrition and oxidative stability of soybean oil compared to other oils. In order to improve the quality of soybean oil and processed foods, chemically mutagenized soybeans have been developed in this project. Seeds harvested from individual M3 and M4 plants (from 2 successive years 2012 and 2013) were analyzed for protein content, oil composition, and content. Moreover, seven phenotypic traits including oil analysis (stearic, palmitic, oleic, linolenic and linoleic), seed protein content, weight of the seeds (High yield), seeds color, stem length, germination rates, and branch architecture were collected and analyzed in this project of soybean `Forrest' mutagenized population. The result of this research showed that there were 25 significantly different lines (p

Book Description
Soybean (Glycine max (L.) Merr.) cyst nematode (SCN) (Heterodera glycines Ichinohe), an obligate sedentary endoparasite, is the most economically destructive pathogen in soybean production and causes over $1 billion in annual losses in the United States. Planting resistant cultivars is the primary management method to control SCN for the long-term purpose, but the nature of genetic resistance is little known. The Rhg1 (Resistance to H. glycines ) locus on chromosome 18 is found as a major quantitative trait locus (QTL) that contributes resistance to SCN. The chemical mutagen ethylmethane sulfonate (EMS) can be utilized to induce genetic mutations in soybean populations, which screened by an efficient reverse genetic strategy known as Targeting Induced Local Lesions IN Genomes (TILLING) for functional gene analyses. The objective of this study was to analyze the function of SNAP gene ( Glyma18g02590 ) at rhg1 allele from `Forrest' (`Peking'-derived SCN resistant cultivar) using TILLING. Soybean cultivar `Forrest' seeds were mutagenized with EMS and grown to generate M1 plants. M1 plants were self-pollinated to produce approximately 3000 M2 plants. Genomic DNAs were extracted from young leaves of individual M2 plants and quantified to normalize concentration of DNAs. The DNA samples were then pooled eight-fold in 96-well plates for mutations screening by TILLING. Moreover, 12 phenotypic traits including chlorophyll deficiency, leaf shape, branch architecture, seed color, seed weight, fatty acid phenotype were identified in the mutagenized population, analyzed and archived in this study.

Book Description
Soybean is one of the most economically important crop species in the world. Allelic series that increase genetic variability are very important resources for crop improvement and gene function studies by reverse genetics. Moreover, mutant varieties are not required to comply with the international Genetically Modified Organism (GMO) regulations, which makes them more acceptable to consumers. Two chemical mutagenized soybean populations of approximately 2,260 and 2,450 M2 families from cultivars 'Forrest' and 'Williams 82' were successfully developed in 2007-2008. A large number of visible morphological phenotypes were identified in these mutagenized populations, such as albinism, abnormal leaflets and black seed coats, which suggested the success of generating genetic variability by mutagenesis. Additionally, a database was established consisting of the pictures of each plant at maturity, some of the morphological and yield characteristics of each plant. Targeting Induced Local Lesions IN Genomes (TILLING) was used to identify the induced mutations in this project.

Book Description
This book examines the application of soybean genome sequences to comparative, structural, and functional genomics. Since the availability of the soybean genome sequence has revolutionized molecular research on this important crop species, the book also describes how the genome sequence has shaped research on transposon biology and applications for gene identification, tilling and positional gene cloning. Further, the book shows how the genome sequence influences research in the areas of genetic mapping, marker development, and genome-wide association mapping for identifying important trait genes and soybean breeding. In closing, the economic and botanical aspects of the soybean are also addressed.
