Cell and Developmental Biology of Arabinogalactan-Proteins


Book Description

Arabinogalactan-proteins are distributed throughout the plant kingdom and are present in leaves, stems, roots, floral parts, and seeds. At the subcellular level, AGPs are localized on the plasma membrane, in the cell wall, in secretory and endocytotic pathway organelles, in stylar and root secretions and in the medium of cultured cells. The widespread distribution of AGPs indicates that they perform important functions. An expansion of knowledge regarding AGPs has been initiated and sustained through new experimental approaches, including the development of monoclonal antibody probes and cloning of cDNAs corresponding to core polypeptides. Regulated expression and other evidence points to the involvement of AGPs in plant reproductive development, pattern formation, and somatic embryogenesis, as well as in the processes of cell division, cell expansion, and cell death. AGPs also have an importance to industry. One example is gum arabic, an exudate from Acacia senegal, a mixture of AGPs and polysaccharides which has unique viscosity and emulsifying properties that have led to many uses in the food as well as other industries.

Somatic Embryogenesis: Fundamental Aspects and Applications


Book Description

This book discusses basic and applied aspects of somatic embryogenesis, one of the most powerful tools in plant biotechnology. It is divided into three parts; Part I includes topics such as the history of this research field, how differentiated plant cells can (re)acquire totipotency, molecular features, as well as the epigenetics and proteomics of somatic embryogenesis. Part II covers the somatic embryogenesis of different crops, such as Agave spp. maize, Cocos nucifera, Bixa orellana, Capsicum spp., Coffea spp., Musa spp., Pinus spp., and Arabidopsis thaliana. Various applications, like scale-up propagation and genetic engineering are discussed in detail in Part III. The book will appeal to plant scientists, plant breeders and experts working in industry.




The Biochemistry of Plants


Book Description

The Biochemistry of Plants, Volume 14: Carbohydrates provides information pertinent to the fundamental aspects of plant biochemistry. This book deals with the function and structure of the plant cell wall by describing the physical and chemical properties of cell wall components. Organized into 11 chapters, this volume begins with an overview of hexose phosphate metabolism in nonphotosynthetic tissues. This text then examines the findings in fructan structures, conformations, and linkages, the enzymes involved in fructan synthesis and degradation, and their cellular regulation, location, and metabolic role in plants. Other chapters consider the methods employing enzymes to determine starch structure. This book discusses as well the different biosynthetic modes of plant cell walls. The final chapter deals with the various environmental factors that influence expression of the ?-amylase gene, suggesting how molecular biology may help in understanding carbohydrate biochemistry and the enzymes involved in carbohydrate synthesis and metabolism. This book is a valuable resource for plant biochemists.




Polarity in Plants


Book Description

The establishment of polarity is a fundamental feature in eukaryotic development. Polarity in Plants provides an account of current research into the mechanisms by which polarity is generated at the level of the cell, organ and organism in plants, drawing especially on recent work with model organisms. The emphasis is on the use of the techniques of molecular genetics to dissect molecular mechanisms. This is the first volume to bring together the diverse aspects of polarity in plant development.




Essentials of Glycobiology


Book Description

Sugar chains (glycans) are often attached to proteins and lipids and have multiple roles in the organization and function of all organisms. "Essentials of Glycobiology" describes their biogenesis and function and offers a useful gateway to the understanding of glycans.




Somatic Embryogenesis


Book Description

Somatic embryogenesis, the initiation of embryos from previously differentiated somatic cells, is a unique process in plants. This volume expands our view of a subject that is important for plant biotechnology, genetics, cell biology, development, and agricultural applications. All chapters present the latest research progress, including functional genomic, genetic, and proteomic approaches. A special focus is placed on the effects of stress, environment, and plant growth regulators on embryogenesis. The role of genes such as Leafy Cotyledons and Baby Boom in defining and maintaining cell competence is discussed.




Plant Cell Walls


Book Description

This work is a comprehensive collection of articles that cover aspects of cell wall research in the genomic era. Some 2500 genes are involved in some way in wall biogenesis and turnover, from generation of substrates, to polysaccharide and lignin synthesis, assembly, and rearrangement in the wall. Although a great number of genes and gene families remain to be characterized, this issue provides a census of the genes that have been discovered so far. The articles comprising this issue not only illustrate the enormous progress made in identifying the wealth of wall-related genes but they also show the future directions and how far we have to go. As cell walls are an enormously important source of raw material, we anticipate that cell-wall-related genes are of significant economic importance. Examples include the modification of pectin-cross-linking or cell-cell adhesion to increase shelf life of fruits and vegetables, the enhancement of dietary fiber contents of cereals, the improvement of yield and quality of fibers, and the relative allocation of carbon to wall biomass for use as biofuels. The book is intended for academic and professional scientists working in the area of plant biology as well as material chemists and engineers, and food scientists who define new ways to use cell walls.




Carbohydrate Bioengineering


Book Description

The Carbohydrate Bioengineering Meeting held in Elsinore, Denmark, April 23-26, 1995, gathered 230 scientists, mostly from Europe, with interest in carbohydrate analysis and structure; carbohydrates in medicine and glycopathology; structure, function, application, and protein engineering of carbohydrate active enzymes; oligo- and polysaccharides of industrial interest; and production of carbohydrate containing new materials. The first chapters address glycoconjugates as modulatory and recognition molecules, structure determination using NMR and mass spectrometry, and microdialysis-chip enzyme-based sensors. Active site mutations coupled with crystal structures and synthetic substrate analogue interactions as well as new three-dimensional structures and binding domains for biotechnological applications are included in the chapters. Carbohydrate active enzymes turned out to be a predominant topic. The rapid development in glycobiology and glycotechnology has resulted in an enormous increase in our knowledge on the structure conversion, and application of carbohydrates in industry and medicine.




Plant Cell Walls


Book Description

Plant cell walls have been relevant for human survival throughout evolution, from cell walls recognised as an essential ingredient in human and livestock nutrition, to their use in energy generation, construction, tool making, paper and clothing. This plant-generated material is at the centre of a myriad of human activities, and it represents the world's most abundant natural resource for fuel, fibre, food and fodder. Plant Cell Walls: Research Milestones and Conceptual Insights provides an overview of the key discoveries of hundreds of years of plant cell wall research. With chapter contributions from prominent scientists in the cell wall field, this book provides a comprehensive treatment of plant cell wall research, accompanied by a historical overview to illustrate how concepts have evolved, and how progress has been enabled by emerging technological advances. Plant Cell Walls: Research Milestones and Conceptual Insights elaborates on the translation of research to application in biotechnology and agriculture, and highlights its relevance for climate change mitigation and adaptation. It will be a key resource for plant cell biologists, biochemists and geneticists.
