Download or read book Genetic and Environmental Control of Steviol Glycoside Biosynthesis in Stevia Rebaudiana written by Jennifer Marie Evans and published by . This book was released on 2014 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stevia rebaudiana (stevia) is gaining agricultural importance due to its natural production of non-caloric steviol glycosides, which can be extracted and incorporated into natural, zero-calorie sweeteners. Of the several steviol glycosides produced by stevia, those produced in the largest concentrations, such as rebaudioside A, are often criticized by consumers as having a bitter aftertaste. Other glycosides, such as rebaudioside D, are reported to have a superior flavor profile, but are produced in much smaller concentrations. The environmental and genetic control of steviol glycoside synthesis is poorly understood. The objectives of this research were: 1) to determine how daily light integral (DLI) influences glycoside concentrations and relative proportions, particularly for rebaudioside D and 2) to elucidate the genetic control of rebaudioside D synthesis from rebaudioside A. DLI influenced both glycoside concentration and relative proportion in a glycoside-specific manner. Using traditional breeding, populations were created via controlled crosses where parents varied in the percentage of rebaudioside D calculated from the total of rebaudiosides A and D. The production of rebaudioside D appears to be regulated by a single dominant gene controlling the presence/absence of the precursor compound, rebaudioside A. Some of the individual populations in this study exhibited correlations unique to each population regarding traits of interest, demonstrating the variability in stevia. Future breeding efforts could harness this variability in addition to knowledge of precursor glycoside content as a resource to improve future stevia lines.

Download or read book Handbook of Sweeteners written by S. Marie and published by Springer Science & Business Media. This book was released on 2013-11-21 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of sweetness and sweeteners has recently been an area well served by books at all levels, but this volume was planned to fill what we perceived as a gap in the coverage. There appeared to be no book which attempted to combine a study of sweetness with a thorough but concise coverage of all aspects of sweeteners. We set out to include all the important classes of sweeteners, including materials which do not yet have regulatory approval, so that clear comparisons could be made between them and their technological advantages and disadvantages. To achieve our first aim, of sufficient depth of coverage, the accounts within this volume are comprehensive enough to satisfy the requirements of a demanding readership, but cannot be exhaustive in a single volume of moderate proportions. The second aim, of breadth and conciseness, is satisfied by careful selection of the most pertinent material. For the purposes of this book, a sweetener is assumed to be any substance whose primary effect is to sweeten a food or beverage to be consumed, thus including both the nutritive and non-nutritive varieties, from the ubiquitous sucrose to the lesser known, newer developments in alternative sweeteners. The volume has its contents structured in a logical manner to enable it to be used in an ordered study of the complete subject area or as a convenient reference source.

Download or read book Plant derived Natural Products written by Anne E. Osbourn and published by Springer Science & Business Media. This book was released on 2009-07-07 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants produce a huge array of natural products (secondary metabolites). These compounds have important ecological functions, providing protection against attack by herbivores and microbes and serving as attractants for pollinators and seed-dispersing agents. They may also contribute to competition and invasiveness by suppressing the growth of neighboring plant species (a phenomenon known as allelopathy). Humans exploit natural products as sources of drugs, flavoring agents, fragrances and for a wide range of other applications. Rapid progress has been made in recent years in understanding natural product synthesis, regulation and function and the evolution of metabolic diversity. It is timely to bring this information together with contemporary advances in chemistry, plant biology, ecology, agronomy and human health to provide a comprehensive guide to plant-derived natural products. Plant-derived natural products: synthesis, function and application provides an informative and accessible overview of the different facets of the field, ranging from an introduction to the different classes of natural products through developments in natural product chemistry and biology to ecological interactions and the significance of plant-derived natural products for humans. In the final section of the book a series of chapters on new trends covers metabolic engineering, genome-wide approaches, the metabolic consequences of genetic modification, developments in traditional medicines and nutraceuticals, natural products as leads for drug discovery and novel non-food crops.

Download or read book Thidiazuron From Urea Derivative to Plant Growth Regulator written by Naseem Ahmad and published by Springer. This book was released on 2018-03-23 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant biotechnology is a most interesting branch for academicians and researchers in recent past. Now days, it becomes a very useful tool in agriculture and medicine and is regarded as a popular area of research especially in biological sciences because it makes an integral use of biochemistry, molecular biology and engineering sciences in order to achieve technological application of cultured tissues, cell and microbes. Plant tissue culture (PTC) refers to a technique of cultivation of plant cells and other parts on artificial nutrient medium in controlled environment under aseptic conditions. PTC requires various nutrients, pH, carbon source, gelling agent, temperature, photoperiod, humidity etc. and most importantly the judicious use of plant growth regulators. Various natural, adenine and phenyl urea derivatives are employed for the induction and proliferation of different types of explants. Several phenyl urea derivatives were evaluated and it was observed that thidiazuron (n-phenyl-N”-1,2,3- thidiazol-5-ulurea) was found to be the most active among the plant growth regulators. Thidiazuron (TDZ) was initially developed as a cotton defoliant and showed high cytokinin like activity. In some examples, its activity was 100 times more than BA in tobacco callus assay and produces more number of shoots in cultures than Zeatin and 2iP. TDZ also showed major breakthrough in tissue culture of various recalcitrant legumes and woody species. For the last two decades, number of laboratories has been working on TDZ with different aspect and number of publications has come out. To the best of our knowledge, there is no comprehensive edited volume on this particular topic. Hence th,e edited volume is a deed to consolidate the scattered information on role of TDZ in plant tissue culture and genetic manipulations that would hopefully prove informative to various researches. Thidiazuron: From Urea Derivative to Plant Growth Regulator compiles various aspects of TDZ in Plant Tissue Culture with profitable implications. The book will provides basic material for academicians and researchers who want to initiate work in this fascinating area of research. The book will contain 26 chapters compiled by International dignitaries and thus giving a holistic view to the edited volume.
