Genetic Engineering: Principles and Methods presents state-of-the-art discussions in modern genetics and genetic engineering. Recent volumes have covered gene therapy research, genetic mapping, plant science and technology, transport protein biochemistry, and viral vectors in gene therapy, among many other topics. Key features of Volume 27 include: - Identification and Analysis of Micrornas - Dormancy and the Cell Cycle - Long distance peptide and metal transport in plants - Signaling in plant response to temperature and water stresses - Nutrient transport and metabolism in plants - Salt Stress Signaling and Mechanisms of Plant Salt Tolerance - Gene cloning and expression - Assisted folding and assembly of proteins

Over the past decade, our laboratory and others have been concerned with molecular archaeological studies aimed at revealing the origins and evolutionary histories of permeases (1). These studies have revealed that several different families, defined on the basis of sequence similarities, arose independently of each other, at different times in evolutionary history, following different routes. When complete microbial genomes first became available for analysis, we adapted p- existing software and designed new programs that allowed us quickly to identify probable transmembrane proteins, estimate their topologies and determine the likelihood that they function in transport (2). This work allowed us to expand previously-recognized families and to identify dozens of new families. All of this work then led us to attempt to design a rational but comprehensive classification system that would be applicable to the complete complement of transport systems found in all living organisms (3). The classification system that we have devised is based primarily on mode of transport and energy coupling mechanism, secondarily on molecular phylogeny, and lastly on the substrate specificities of the individual permeases (4).

Genetic Engineering, Volume 24 contains discussions of contemporary and relevant topics in genetics, including: -Gene silencing: principles and applications, -Integrins and the myocardium, -Plant virus gene vectors: biotechnology and applications in agriculture and medicine, -Novel approaches to controlling transcription, -Use of DNA polymorphisms in genetic mapping, -Application of FLP/FRT site-specific DNA recombination system in plants. This principles and methods approach to genetics and genetic engineering is essential reading for all academics, bench scientists, and industry professionals wishing to take advantage of the latest and greatest in this continuously emerging field.

Aspects of genetic engineering research emphasized in this volume are applications to plants (crop plants and grass, both important for human needs) and new methodologies, such as Tar cloning, which make it much easier to isolate specific regions from complex genomes. Another subject discussed is linear DNA replication of prokaryotes.

This volume is the first of a series concerning a new tech nology which is revolutionizing the study of biology, perhaps as profoundly as the discovery of the gene. As pointed out in the introductory chapter, we look forward to the future impact of the technology, but cannot see where it might take us. The purpose of these volumes is to follow closely the explosion of new tech niques and information that is occurring as a result of the newly acquired ability to make particular kinds of precise cuts in DNA molecules. Thus we are particularly committed to rapid publication. Jane K. Setlow Alexander Hollaender v INTRODUCTION AND HISTORICAL BACKGROUND 1 Maxine F.
