Download or read book Molecular Characterization of the Low Molecular Weight Glutenin Subunit Gene Family Members and Their Effect on Wheat Quality written by Maria Itria Ibba and published by . This book was released on 2018 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gluten is a macro polymer responsible for the unique viscoelastic properties of wheat dough and it is formed from the interaction of wheat seed storage proteins. The low-molecular-weight glutenin subunits (LMW-GSs) are one of the major components of gluten and play a critical role in the determination of wheat end-use quality. However, a clear association between different LMW-GSs and wheat quality is not well understood. The LMW-GSs are in fact hard to differentiate both at genic and protein level. They are encoded by a multigene family located on the short arm of the homoeologous group 1 chromosomes at the Glu-3 loci. The number of LMW-GS genes in each wheat variety differs and there is evidence that genes at each Glu-3 locus are divided by large intergenic and highly recombinogenic regions. Also, LMW-GSs are highly similar in structure among themselves and with many gliadins making them difficult to differentiate at the protein level. For these reasons, the identification of different LMW-GS protein profiles has been challenging, and conflicting results on the association between LMW-GS alleles and wheat end-use quality have been reported. The objective of this project was to develop a better understanding of the genetics of the LMW-GSs and of the role that each LMW-GS gene has in the determination of wheat end-use quality. First a set of common wheat varieties identified as standards for the Glu-3 alleles were analyzed for their LMW-GS genic profile to verify whether there was an association between a specific genic profile and the relative Glu-3 allele. Then, the genetic linkage between the LMW-GS genes at each Glu-3 locus was investigated to develop a better understanding of the Glu-3 loci structure. The results obtained from the two previous analyses were used to better interpret and characterize the LMW-GS profile of a set of elite bread wheat varieties and to correlate specific LMW-GS genes to different dough rheology parameters. Finally, a set of molecular markers specific for each LMW-GS haplotype was developed to facilitate the analysis of the LMW-GSs in wheat breeding programs. Results of this project will greatly improve the current knowledge of the LMW-GSs.

This book was released on 2020-03-17 with total page 557 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wheat Quality for Improving Processing and Human Health brings together an international group of leading wheat scientists to outline highly relevant and diverse aspects and the latest advances in understanding of the world’s most consumed cereal. Topics covered include LMW glutenins, starch-related proteins, and the impact of processing on composition and consumer health. Individual chapters focus on important factors such as FODMAPs, protein structure, dough viscoelasticity and fumonisins. The environmental effects on allergen content are comprehensively covered, as are phenolic compounds and molecular markers. The major quality screening tools and genetic resources are reviewed in depth. Gluten is a major focus of this work with chapters dedicated to health effects, analytical methods and standards, proteomics and mutant proteins. Starting in 2015, wheat quality scientists from across the globe have united to develop the Expert Working Group for Improving Wheat Quality for Processing and Health under the umbrella of the Wheat Initiative. This joint effort provides a framework to establish strategic research and organisation priorities for wheat research at the international level in both developed and developing countries. This Expert Working Group aims to maintain and improve wheat quality for processing and health under varying environmental conditions. The Group focuses on a broad range of wheat quality issues including seed proteins, carbohydrates, nutrition quality and micronutrient content, grain processing and food safety. Bioactive compounds are also considered, both those with negative effects such as allergens and mycotoxins, and those with positive effects such as antioxidants and fibre. The Group also works in the development of germplasm sets and other tools that promote wheat quality research. Wheat quality specialists working on the wheat value chain, and nutritionists will find this book a useful resource to increase and update their knowledge of wheat quality, nutrition and health issues.

Download or read book Genetics and Genomics of the Triticeae written by Catherine Feuillet and published by Springer Science & Business Media. This book was released on 2009-06-10 with total page 774 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sequencing of the model plant genomes such as those of A. thaliana and rice has revolutionized our understanding of plant biology but it has yet to translate into the improvement of major crop species such as maize, wheat, or barley. Moreover, the comparative genomic studies in cereals that have been performed in the past decade have revealed the limits of conservation between rice and the other cereal genomes. This has necessitated the development of genomic resources and programs for maize, sorghum, wheat, and barley to serve as the foundation for future genome sequencing and the acceleration of genomic based improvement of these critically important crops. Cereals constitute over 50% of total crop production worldwide (http://www.fao.org/) and cereal seeds are one of the most important renewable resources for food, feed, and industrial raw materials. Crop species of the Triticeae tribe that comprise wheat, barley, and rye are essential components of human and domestic animal nutrition. With 17% of all crop area, wheat is the staple food for 40% of the world’s population, while barley ranks fifth in the world production. Their domestication in the Fertile Crescent 10,000 years ago ushered in the beginning of agriculture and signified an important breakthrough in the advancement of civilization. Rye is second after wheat among grains most commonly used in the production of bread and is also very important for mixed animal feeds. It can be cultivated in poor soils and climates that are generally not suitable for other cereals. Extensive genetics and cytogenetics studies performed in the Triticeae species over the last 50 years have led to the characterization of their chromosomal composition and origins and have supported intensive work to create new genetic resources. Cytogenetic studies in wheat have allowed the identification and characterization of the different homoeologous genomes and have demonstrated the utility of studying wheat genome evolution as a model for the analysis of polyploidization, a major force in the evolution of the eukaryotic genomes. Barley with its diploid genome shows high collinearity with the other Triticeae genomes and therefore serves as a good template for supporting genomic analyses in the wheat and rye genomes. The knowledge gained from genetic studies in the Triticeae has also been used to produce Triticale, the first human made hybrid crop that results from a cross between wheat and rye and combines the nutrition quality and productivity of wheat with the ruggedness of rye. Despite the economic importance of the Triticeae species and the need for accelerated crop improvement based on genomics studies, the size (1.7 Gb for the bread wheat genome, i.e., 5x the human genome and 40 times the rice genome), high repeat content (>80%), and complexity (polyploidy in wheat) of their genomes often have been considered too challenging for efficient molecular analysis and genetic improvement in these species. Consequently, Triticeae genomics has lagged behind the genomic advances of other cereal crops for many years. Recently, however, the situation has changed dramatically and robust genomic programs can be established in the Triticeae as a result of the convergence of several technology developments that have led to new, more efficient scientific capabilities and resources such as whole-genome and chromosome-specific BAC libraries, extensive EST collections, transformation systems, wild germplasm and mutant collections, as well as DNA chips. Currently, the Triticeae genomics "toolbox" is comprised of: - 9 publicly available BAC libraries from diploid (5), tetraploid (1) and hexaploid (3) wheat; 3 publicly available BAC libraries from barley and one BAC library from rye; - 3 wheat chromosome specific BAC libraries; - DNA chips including commercially available first generation chips from AFFYMETRIX containing 55’000 wheat and 22,000 barley genes; - A large number of wheat and barley genetic maps that are saturated by a significant number of markers; - The largest plant EST collection with 870’000 wheat ESTs, 440’000 barley ESTs and about 10’000 rye ESTs; - Established protocols for stable transformation by biolistic and agrobacterium as well as a transient expression system using VIGS in wheat and barley; and - Large collections of well characterized cultivated and wild genetic resources. International consortia, such as the International Triticeae Mapping Initiative (ITMI), have advanced synergies in the Triticeae genetics community in the development of additional mapping populations and markers that have led to a dramatic improvement in the resolution of the genetic maps and the amount of molecular markers in the three species resulting in the accelerated utilization of molecular markers in selection programs. Together, with the development of the genomic resources, the isolation of the first genes of agronomic interest by map-based cloning has been enabled and has proven the feasibility of forging the link between genotype and phenotype in the Triticeae species. Moreover, the first analyses of BAC sequences from wheat and barley have allowed preliminary characterizations of their genome organization and composition as well as the first inter- and intra-specific comparative genomic studies. These later have revealed important evolutionary mechanisms (e.g. unequal crossing over, illegitimate recombination) that have shaped the wheat and barley genomes during their evolution. These breakthroughs have demonstrated the feasibility of developing efficient genomic studies in the Triticeae and have led to the recent establishment of the International Wheat Genome Sequencing Consortium (IWGSC) (http//:www.wheatgenome.org) and the International Barley Sequencing Consortium (www.isbc.org) that aim to sequence, respectively, the hexaploid wheat and barley genomes to accelerate gene discovery and crop improvement in the next decade. Large projects aiming at the establishment of the physical maps as well as a better characterization of their composition and organization through large scale random sequencing projects have been initiated already. Concurrently, a number of projects have been launched to develop high throughput functional genomics in wheat and barley. Transcriptomics, proteomics, and metabolomics analyses of traits of agronomic importance, such as quality, disease resistance, drought, and salt tolerance, are underway in both species. Combined with the development of physical maps, efficient gene isolation will be enabled and improved sequencing technologies and reduced sequencing costs will permit ultimately genome sequencing and access to the entire wheat and barley gene regulatory elements repertoire. Because rye is closely related to wheat and barley in Triticeae evolution, the latest developments in wheat and barley genomics will be of great use for developing rye genomics and for providing tools for rye improvement. Finally, a new model for temperate grasses has emerged in the past year with the development of the genetics and genomics (including a 8x whole genome shotgun sequencing project) of Brachypodium, a member of the Poeae family that is more closely related to the Triticeae than rice and can provide valuable information for supporting Triticeae genomics in the near future. These recent breakthroughs have yet to be reviewed in a single source of literature and current handbooks on wheat, barley, or rye are dedicated mainly to progress in genetics. In "Genetics and Genomics of the Triticeae", we will aim to comprehensively review the recent progress in the development of structural and functional genomics tools in the Triticeae species and review the understanding of wheat, barley, and rye biology that has resulted from these new resources as well as to illuminate how this new found knowledge can be applied for the improvement of these essential species. The book will be the seventh volume in the ambitious series of books, Plant Genetics and Genomics (Richard A. Jorgensen, series editor) that will attempt to bring the field up-to-date on the genetics and genomics of important crop plants and genetic models. It is our hope that the publication will be a useful and timely tool for researchers and students alike working with the Triticeae.
Download or read book Advances in Seed Biology written by Paolo A. Sabelli and published by Frontiers Media SA. This book was released on 2015-11-11 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The seed plays a fundamental role in plant reproduction as well as a key source of energy, nutrients and raw materials for developing and sustaining humanity. With an expanding and generally more affluent world population projected to reach nine billion by mid-century, coupled to diminishing availability of inputs, agriculture is facing increasing challenges to ensure sufficient grain production. A deeper understanding of seed development, evolution and physiology will undoubtedly provide a fundamental basis to improve plant breeding practices and ultimately crop yields. Recent advances in genetic, biochemical, molecular and physiological research, mostly brought about by the deployment of novel high-throughput and high-sensitivity technologies, have begun to uncover and connect the molecular networks that control and integrate different aspects of seed development and help determine the economic value of grain crops with unprecedented details. The objective of this e-book is to provide a compilation of original research articles, reviews, hypotheses and perspectives that have recently been published in Frontiers in Plant Science, Plant Evolution and Development as part of the Research Topic entitled "Advances in Seed Biology". Editing this Research Topic has been an extremely interesting, educational and rewarding experience, and we sincerely thank all authors who contributed their expertise and in-depth knowledge of the different topics discussed. We hope that the information presented here will help to establish the state of the art of this field and will convey how exciting and important studying seeds is and hopefully will stimulate a new crop of scientists devoted to investigating the biology of seeds.
