The Arthur M. Sackler Colloquia of the National Academy of Sciences address scientific topics of broad and current interest, cutting across the boundaries of traditional disciplines. Each year, four or five such colloquia are scheduled, typically two days in length and international in scope. Colloquia are organized by a member of the Academy, often with the assistance of an organizing committee, and feature presentations by leading scientists in the field and discussions with a hundred or more researchers with an interest in the topic. Colloquia presentations are recorded and posted on the National Academy of Sciences Sackler colloquia website and published on CD-ROM. These Colloquia are made possible by a generous gift from Mrs. Jill Sackler, in memory of her husband, Arthur M. Sackler.

This book assesses the scientific value and merit of research on human genetic differencesâ€"including a collection of DNA samples that represents the whole of human genetic diversityâ€"and the ethical, organizational, and policy issues surrounding such research. Evaluating Human Genetic Diversity discusses the potential uses of such collection, such as providing insight into human evolution and origins and serving as a springboard for important medical research. It also addresses issues of confidentiality and individual privacy for participants in genetic diversity research studies.

Two decades ago, recombinant DNA technology or genetic engineering ushered in a new era in the study of plant viruses. The major breakthrough came in the eighties, primarily due to the development of new methods for RNA reverse transcription and cDNA cloning, along with restriction enzyme mapping and rapid nucleotide sequencing. An information explosion in various molecular aspects of plant viruses was caused by these studies. Current research efforts investigate the study of viral genomes, genetic maps, genes and gene expression, gene products, and genetic basis of virus functions and biological properties. Molecular Biology of Plant Viruses analyzes, collates and reviews such published information. Additionally, it demonstrates the mechanisms of genetic variability; brings out the molecular basis of virus transport in plants and of virus transmission by vectors and of disease symptomatology; and discusses molecular biology of viroids and transgenic plants. It also treats the recently discovered genetic phenomenon of gene silencing and the gene-for-gene interactions between the hosts and plant viruses. Molecular Biology of Plant Viruses is an excellent reference, providing insight into the exciting research developments made in the field.

The purpose of this book is to present a new theory of mutation-driven evolution, which is based on recent advances in genomics and evolutionary developmental biology. This theory asserts that the driving force of evolution is mutation and natural selection is of secondary importance.

Virus as Composition, Complexity, Quasispecies, Dynamics, and Biological Implications, Second Edition, explains the fundamental concepts surrounding viruses as complex populations during replication in infected hosts. Fundamental phenomena in virus behavior, such as adaptation to changing environments, capacity to produce disease, and the probability to be transmitted or respond to treatment all depend on virus population numbers. Concepts such as quasispecies dynamics, mutations rates, viral fitness, the effect of bottleneck events, population numbers in virus transmission and disease emergence, and new antiviral strategies are included. The book's main concepts are framed by recent observations on general virus diversity derived from metagenomic studies and current views on the origin and role of viruses in the evolution of the biosphere. Features current views on key steps in the origin of life and origins of viruses Includes examples relating ancestral features of viruses with their current adaptive capacity Explains complex phenomena in an organized and coherent fashion that is easy to comprehend and enjoyable to read Considers quasispecies as a framework to understand virus adaptability and disease processes
