Download or read book Transgenesis and Secondary Metabolism written by Sumita Jha and published by Springer. This book was released on 2017-05-16 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook provides comprehensive reference information on the efficient production of secondary metabolites from plants by transgenesis and other genetic manipulation strategies. It reviews and summarizes selected important case studies in genetic methods applied to enhance the production of a given metabolite or a group of related or derived compounds. Readers will find reference information on a multitude of techniques and methods, including traditional breeding and screening; over-expression of genes encoding key enzymes; functional genomics approaches; metabolic engineering of the relevant biosynthetic pathways; indirect genetic approaches to improve metabolite production, including Agrobacterium mediated transformations. Furthermore, combinatorial biochemistry approaches to engineer secondary metabolic pathways are summarized, which can offer access to new structures or to the design of novel compounds. Since many commercially valuable substances are still extracted from plants, being largely inaccessible to efficient modern laboratory synthesis methods, this book provides a valuable resource of information for biotechnological approaches that can help to find alternative and more efficient methods for the production of natural secondary metabolites. Thus adjusted production methods, with the help of tailored plant systems, can potentially help to release the stress on plants, which are currently suffering from extensive human harvesting, and to conserve global biodiversity. Readers will find comprehensive reference information on plant genetic manipulation toward more efficient synthesis, accumulation and production of target secondary metabolites. The handbook will appeal to researchers and professionals, but also graduate students and scholars working in the fields of biotechnology, genetic engineering, medicinal plant research, pharmacy, and phytochemistry.

Book excerpt: Addressing the pear genome, this book covers the current state of knowledge regarding genetic and genomic resources, breeding approaches and strategies, as well as cutting-edge content on how these tools and resources are being / soon will be utilized to pursue genetic improvement efforts that will combine fruit quality, high productivity, precocious fruit bearing, and long postharvest storage life, along with elevated levels of resistance to various major diseases and insect pests. Throughout, the book also explores potential opportunities and challenges in genomic analysis, sequence assembly, structural features, as well as functional studies that will assist in future genetic improvement efforts for pears. The pear (Pyrus), an important tree fruit crop, is grown worldwide, and has several economically relevant cultivars. In recent years, modern genetic and genomic tools have resulted in the development of a wide variety of valuable resources for the pear. In the past few years, completion of whole genome assemblies of ‘Dangshansuli’, an Asian pear, and ‘Bartlett’, a European pear, have paved the way for new discoveries regarding for example, the pear’s genomic structure, chromosome evolution, and patterns of genetic variation. This wealth of new resources will have a major impact on our knowledge of the pear genome; in turn, these resources and knowledge will have significant impacts on future genetic improvement efforts.
Download or read book Physiological and Molecular Changes Induced in Catharanthus Roseus in Response to Phytoplasma Infection written by Melanie Geraldine Tuffen and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Phytoplasmas are specialised plant pathogenic bacteria, transmitted by sap sucking insect vectors and responsible are for a number of economically important crop diseases. Typical disease symptoms include phyllody, virescence, little leaf, increased branching, stunting and yellowing. Catharanthus roseus, or Madagascar periwinkle, is often used as an experimental host for phytoplasma disease due to the fact that infection produces a good range of representative symptoms. Very little is known about the mechanisms of phytoplasma pathogenicity, and the main aim of this study was to learn more about changes induced in C. rose us in response to phytoplasma infection. Sweet potato little leaf (SPLL) infection induces a reduction in leaf size in C. roseus. Leaf size is controlled by two main mechanisms, initially leaves grow via mitotic divisions but when these cease a period of cell expansion occurs. Upper epidermal cells of healthy and SPLL infected plants were investigated for histological changes at the 2nd and 5th leaf stage. At all stages there was a reduction in cell size, though this was not always enough to account for total reduction in leaf size suggesting some inhibition of cell proliferation occurs. The leaf ratio was affected positively in SPLL infected plants, suggesting disease has a greater affect on growth in the width direction than the length. Phyllody is defined as the replacement of flowers with leaf like structures, but very little work has been done on investigating the actual properties of phyllodous leaves. The upper epidermis of flowers from soybean phyllody (SP) infected plants was investigated. In general three cell types were found: conical cells, cells that resembled closely those from the upper epidermis of leaves and cells that appeared to be a hybrid between the two, with a flattened conical cell appearance. Though C. roseus provides a useful host for phytoplasma disease, it lacks the genomic resources available to other species. The Xspecies microarray technique allows the use of a microarray for a species it was not originally designed for. In this instance transcripts from SPLL infected C. rose us were run on the ATH1 Arabidopsis GeneChip®. A hybridisation efficiency of 150 was chosen. The micro array indicated up-regulation of ARF7 and PIN6, genes involved in auxin response and transport, as well as two miRNA processing genes, HASTY and XRN3. Down-regulation of genes involved in photosynthesis was observed. The expression of a number of transcripts was then monitored with quantitative PCR. In general, the qPCR results were not in agreement with the array data. This could be a result of the probes actually binding to other, closely related transcripts within the C. rose us genome. Changes in phytohormones occur in many plant infections, and have been proposed as an explanation for the symptoms seen in phytoplasma infected plants. The levels of cytokinins were measured in the stem, root, leaf and floral tissues of healthy and infected plants, but no significant changes in cytokinin content were seen. A semi-quantitative technique was used to study changes in gene expression in auxin and cytokinin responsive genes. Down-regulation of the cytokinin receptor was seen in all tissues except the leaf. An increase in expression of the auxin influx carrier AUX1 occurred within infected root material, but the transcript was dramatically down regulated in other tissues. It is evident that changes in gene expression occur in infected plants. Gene expression is repressed by DNA methylation. Changes in DNA methylation were monitored using Methylation Sensitive AFLP. Changes in CpNpG methylation were detected in plants infected with Vinca coconut phyllody and Rhemannia glutinosa. Some isolated sequences returned showed homology to the chloroplast and mitochondrial genomes. These organelle genomes were thought to be free of cytosine methylation, raising questions about whether this hypothesis is correct.

Download or read book The Kiwifruit Genome written by Raffaele Testolin and published by Springer. This book was released on 2016-05-02 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the basic botanical features of kiwifruit and its wild relatives, reports on the steps that led to its genome sequencing, and discusses the results obtained with the assembly and annotation. The core chapters provide essential insights into the main gene families that characterize this species as a crop, including the genes controlling sugar and starch metabolism, pigment biosynthesis and degradation, the ascorbic-acid pathway, fruit softening and postharvest metabolism, allergens, and resistance to pests and diseases. The book offers a valuable reference guide for taxonomists, geneticists and horticulturists. Further, since information gained from the genome sequence is extraordinarily useful in assessing the breeding value of individuals based on whole-genome scans, it will especially benefit plant breeders. Accordingly, chapters are included that focus on gene introgression from wild relatives and genome-based breeding.

All of these topics are integrated into a main theme of "enabling plant biotechnology" relevant to the production of secondary metabolites. This book will be of great value to all plant cell biologists and molecular geneticists, and all those interested in the integration of plant science and bioprocess engineering for development of enabling technology relevant to the production of plant secondary metabolites.
Download or read book From Functional Genomics to Biotechnology in Ornamental Plants written by Swee-Suak Ko and published by Frontiers Media SA. This book was released on 2019-07-12 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: For centuries plants of a broad taxonomical background have been bred and commercialized because of the beauty of their flowers. However, until recently genomic analyses of ornamentals remained a challenge because of their large genome sizes and high ploidy levels. In the last decade, increasingly affordable sequencing technologies and powerful bioinformatic approaches resulted in the complete sequencing of several horticultural species genomes and the characterization of their transcriptomes. These developments enabled research on many challenging topics. This Research Topic gives you a primer into them by featuring a broad range of original research contributions on some of the most active areas of ornamental plant research: the genetic basis of flower morphology, scent, and color, the genetic regulation of physiology as well as the epigenetic factors affecting vegetative development. In this context, one of the most significant hurdles to functional genetic studies in ornamentals is achieving efficient genetic transformation. Several articles in this Research Topic describe strategies to tackle this challenge and present insights into the way transgene activity renders novel flower phenotypes.

Download or read book Virus Induced Gene Silencing written by Annette Becker and published by Humana Press. This book was released on 2013-02-06 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants are amazing organisms to study, some are important sources for pharmaceuticals, and others can help to elucidate molecular mechanisms required for a plant’s development and its interactions with the biotic or abiotic environment. Functional genomics is vastly lagging behind the speed of genome sequencing as high-throughput gene function assays are difficult to design, specifically for non-model plants. Bioinformatics tools are useful for gene identification and annotation but are of limited value for predictions concerning gene functions as gene functions are uncovered best by experimental approaches. Virus-Induced-Gene-Silencing (VIGS) is an easy to use, fast, and reliable method to achieve down regulation of target gene expression. Virus-Induced Gene Silencing: Methods and Protocols provides detailed protocols for VIGS experiments in several plant species including model and non-model plants. Also included in this book are recently developed protocols for VIGS-derived microRNA production in the plant or protein over expression, as well as chapters devoted to summarizing the molecular mechanisms of VIGS action and the vector systems developed so far. Written in the successful Methods in Molecular BiologyTM series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, Virus-Induced Gene Silencing: Methods and Protocols serves as a valuable resource for researchers from diverse fields of plant biology interested in experimental approaches to analyzing gene functions.
