The seminal text Plant Virology is now in its fifth edition. It has been 10 years since the publication of the fourth edition, during which there has been an explosion of conceptual and factual advances. The fifth edition of Plant Virology updates and revises many details of the previous edition while retaining the important earlier results that constitute the field's conceptual foundation. Revamped art, along with fully updated references and increased focus on molecular biology, transgenic resistance, aphid transmission, and new, cutting-edge topics, bring the volume up to date and maintain its value as an essential reference for researchers and students in the field. - Thumbnail sketches of each genera and family groups - Genome maps of all genera for which they are known - Genetic engineered resistance strategies for virus disease control - Latest understanding of virus interactions with plants, including gene silencing - Interactions between viruses and insect, fungal, and nematode vectors - Contains over 300 full-color illustrations

This book describes the history of tobacco genomics, from its “discovery” by Europeans to next-generation omics approaches in plant science. The authors primarily focus on the allotetraploid common tobacco plant (N. tabacum); however, separate chapters are dedicated to closely related Nicotiana species, such as N. benthamiana and N. attenuata, for which substantial progress in omics data analysis has been already achieved. While genetic maps, transcriptomes, and physical maps of BAC libraries have significantly enhanced our understanding of the tobacco plant, the genome of tobacco and related Nicotiana species has opened a new era in modern tobacco research. This book addresses current and future industrial and research applications as well as central challenges in tobacco science, including diseases, low variability of cultivars, the genome’s large size, polyploidy, and gene duplication.

The pharmacopoeias of most African countries are available and contain an impressive number of medicinal plants used for various therapeutic purposes. Many African scholars have distinguished themselves in the fields of organic chemistry, pharmacology, and pharmacognosy and other areas related to the study of plant medicinal plants. However, until now, there is no global standard book on the nature and specificity of chemicals isolated in African medicinal plants, as well as a book bringing together and discussing the main bioactive metabolites of these plants. This book explores the essence of natural substances from African medicinal plants and their pharmacological potential. In light of possible academic use, this book also scans the bulk of African medicinal plants extract having promising pharmacological activities. - The book contains data of biologically active plants of Africa, plant occurring compounds and synthesis pathways of secondary metabolites - This book explores the essence of natural substances from African medicinal plants and their pharmacological potential - The authors are world reknowned African Scientists

The agricultural sector of medicinal (including plant stimulants) and aromatic plants is characterized by an enormous number and diversity of species. Only a few of them can be considered cultivated crops in which significant breeding efforts are made. For most species, however, breeding is performed in short-term projects only. Therefore, basic knowledge about these species is still fragmentary. Our intention is to compile and organize the available information on the most commonly utilized plant species into one publication, thereby providing a standardized resource for the researchers and the grower community. This book therefore provides reference source materials for a wide variety of plant species used for human consumption due to their flavor, medicinal or recreational properties. It is divided into a section of general topics on genetic resources, breeding adaptation of analytic methods and a compilation of basic data for DNA content, chromosome number and mating system followed by a section of 20 monographs on a species or species groups.

Computational Non-coding RNA Biology is a resource for the computation of non-coding RNAs. The book covers computational methods for the identification and quantification of non-coding RNAs, including miRNAs, tasiRNAs, phasiRNAs, lariat originated circRNAs and back-spliced circRNAs, the identification of miRNA/siRNA targets, and the identification of mutations and editing sites in miRNAs. The book introduces basic ideas of computational methods, along with their detailed computational steps, a critical component in the development of high throughput sequencing technologies for identifying different classes of non-coding RNAs and predicting the possible functions of these molecules. Finding, quantifying, and visualizing non-coding RNAs from high throughput sequencing datasets at high volume is complex. Therefore, it is usually possible for biologists to complete all of the necessary steps for analysis. - Presents a comprehensive resource of computational methods for the identification and quantification of non-coding RNAs - Introduces 23 practical computational pipelines for various topics of non-coding RNAs - Provides a guide to assist biologists and other researchers dealing with complex datasets - Introduces basic computational methods and provides guidelines for their replication by researchers - Offers a solution to researchers approaching large and complex sequencing datasets

This book provides for the first time a single comprehensive source of information on the analytical chemistry of nicotine and related alkaloids. The editors have brought together scientists from academia and the tobacco industry to describe the state-of-the-art of the chemistry and analytical methods for measurement of nicotine. Both the scope and detail of the book are impressive. Chapters describe the history, pharmacology and toxicology of nicotine, the biosynthesis of nicotine and other alkaloids in the tobacco plant, the general chemistry of nicotine and the analytical methodologies that have been used to measure nicotine and related alkaloids in biological specimens, in tobacco and pharmaceutical products and in tobacco smoke. There is also a comprehensive review of the chemistry and toxicology of nicotine-derived nitrosamines, an important class of tobacco carcinogens.

This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.
