Book Description
Plants have numerous fatty acid desaturase (FAD) enzymes regulating the unsaturation of fatty acids, which are encoded by a FAD gene family. The FAD2 genes belong to such family and play a vital role in converting monounsaturated oleic acid to polyunsaturated linoleic acid. Oleic acid has the health benefits for humans, such as reduction in cholesterol level, antioxidation property, and industrial benefits like longer shelf life. The development of genotypes with high oleic acid content in seeds has become one of the primary goals in breeding oilseed plants. The identification and characterization of the FAD2 genes in plants have been an important step to better manipulate gene expression to improve the seed oil quality. The induction of mutations in FAD2 genes to reduce FAD2 enzyme activity has been an integral approach to generate genotypes with high oleic acid. This chapter will describe the FAD2 gene family in the model organism soybean and the correction of mutations in FAD2 genes with the increase of oleic acid content. Leveraging advanced research of FAD2 gene family in soybean promotes the study of FAD2 genes in other legume species, including peanut. The future perspectives and challenges associated with mutations in FAD2 genes will be discussed.

Book Description
Soybean (Glycine max L. (Merr)) is one of the most important crops worldwide. Soybean seeds are vital for both protein meal and vegetable oil. Soybean was domesticated in China, and since last 4-5 decades it has become one of the most widely grown crops around the globe. The crop is grown on an anticipated 6% of the world’s arable land, and since the 1970s, the area in soybean production has the highest percentage increase compared to any other major crop. It is a major crop in the United States, Brazil, China and Argentina and important in many other countries. The cultivated soybean has one wild annual relative, G. soja, and 23 wild perennial relatives. Soybean has spread to many Asian countries two to three thousand years ago, but was not known in the West until the 18th century. Among the various constraints responsible for decrease in soybean yields are the biotic and abiotic stresses which have recently increased as a result of changing climatic scenarios at global level. A lot of work has been done for cultivar development and germplasm enhancement through conventional plant breeding. This has resulted in development of numerous high yielding and climate resilient soybean varieties. Despite of this development, plant breeding is long-term by nature, resource dependent and climate dependent. Due to the advancement in genomics and phenomics, significant insights have been gained in the identification of genes for yield improvement, tolerance to biotic and abiotic stress and increased quality parameters in soybean. Molecular breeding has become routine and with the advent of next generation sequencing technologies resulting in SNP based molecular markers, soybean improvement has taken a new dimension and resulted in mapping of genes for various traits that include disease resistance, insect resistance, high oil content and improved yield. This book includes chapters from renowned potential soybean scientists to discuss the latest updates on soybean molecular and genetic perspectives to elucidate the complex mechanisms to develop biotic and abiotic stress resilience in soybean. Recent studies on the improvement of oil quality and yield in soybean have also been incorporated.

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.

Book Description
Plants are an important source of fats and oils, which are essential for the human diet. In recent years, genomics of oil biosynthesis in plants have attracted great interest, especially in high oil-bearing plants, such as sesame, olive, sunflower, and palm. Considering that, genome sequencing projects of these plants have been undertaken with the help of advanced genomics tools such as next generation sequencing. Several genome sequencing projects of oil crops are in progress and many others are en route. In addition to genome information, advanced genomics approaches are discussed such as transcriptomics, genomics-assisted breeding, genome-wide association study (GWAS), genotyping by sequencing (GBS), and CRISPR. These have all improved our understanding of the oil biosynthesis mechanism and breeding strategies for oil production. There is, however, no book that covers the genomes and genomics of oil crops. For this reason, in this volume we collected the most recent knowledge of oil crop genomics for researchers who study oil crop genomes, genomics, biotechnology, pharmacology, and medicine. This book covers all genome-sequenced oil crops as well as the plants producing important oil metabolites. Throughout this book, the latest genomics developments and discoveries are highlighted as well as open problems and future challenges in oil crop genomics. In doing so, we have covered the state-of-the-art of developments and trends of oil crop genomics.

Book Description
Soybean is the most important oilseed and livestock feed crop in the world. These dual uses are attributed to the crop's high protein content (nearly 40% of seed weight) and oil content (approximately 20%); characteristics that are not rivaled by any other agronomic crop. Across the 10-year period from 2001 to 2010, world soybean production increased from 168 to 258 million metric tons (54% increase). Against the backdrop of soybean's striking ascendancy is increased research interest in the crop throughout the world. Information in this book presents a comprehensive view of research efforts in genetics, plant physiology, agronomy, agricultural economics, and nitrogen relationships that will benefit soybean stakeholders and scientists throughout the world. We hope you enjoy the book.

Book Description
Model plants are required for research when targeted plant species are difficult to study or when research material is unavailable. Importantly, knowledge gained from model plants can be generally translated to other related plant species because many key cellular and molecular processes are conserved and regulated by ‘blueprint’ genes inherited from a common ancestor. Model Organisms in Plant Genetics addresses characteristics of model plants such as Arabidopsis, moss, soybean, maize, and cotton, highlighting their advantages and limitations as well as their importance in studies of plant development, plant genome polyploidization, adaptive selection, evolution, and domestication, as well as their importance in crop improvement.

Book Description
Soybean [Glycine max (L.) Merr.] is the largest oilseed crop produced and consumed worldwide. As an oilseed, soybean provides high quality protein for livestock and poultry feed, and the oil is used extensively in the cooking and food manufacturing industries across the world. Soybean producers have targeted improved oil traits as a priority area of research to enhance the market share of U.S. soybean. Soybean seed is approximately 18% oil and standard commodity soybean oil is a mixture of five fatty acids; palmitic (11%), stearic (4%), oleic (22%), linoleic (53%), and linolenic (8%). Oils high in monounsaturated fatty acids possess increased oxidative stability which negates the need for hydrogenation and eliminates the production of trans-fats. Food products containing trans-fatty acids are currently a major health concern and as such, soybean breeders and molecular geneticists have been challenged to efficiently alter the fatty acid composition to meet the specific needs of the various industries. Fatty acid desaturases are enzymes responsible for the insertion of double bonds (normally in the Z or cis conformation) into alkyl chains, following the abstraction of two hydrogen atoms. The physical properties and nutritional value of many animal and plant storage lipids are determined by desaturases. The quality of soybean oil is of paramount importance both economically and from a nutritional stand point and depends to a large extent on the ratio of polyunsaturated to monounsaturated fatty acid. Temperature also plays an important role in the final lipid content of oil seed plants. In this study, we designed and used gene-specific primers to the following fatty acid desaturases; stearoyl-ACP desaturase (SACPD), omega-6 fatty acid desaturase (FAD2-1), and omega-3 fatty acid desaturase (FAD3), to characterize soybean varieties. We further determined the effect of temperature on the expression of these desaturase genes by quantifying transcript accumulation at various.
