The newest installment in this superb series presents descriptions of the latest DNA recombinants molecule technology. The text combines reports on basic research in genetics with discussions of specific new industrial applications (as well as refinements of older ones) that are likely to prove highly profitable in the years to come.

This volume, as with the previous books in the series, presents state-of-the-art discussions in genetics and genetic engineering by focusing on plant science and technology, agriculture, cell biology, and medical research.

Volume 18 explores the latest advances in recombinant DNA molecule techniques and how they are revolutionizing basic research in biology. Chapters discuss obtaining good expression of genetically engineered pest-resistant genes introduced in crop plants, cloning DNAs containing palindromes, and identifying genes by 3' terminal exon trapping and much more.

Volume 17 of this highly acclaimed series features discussions on a new method of mapping and manipulating DNA with the use of RecA protein in combination with restriction enzymes, RNA pseudoknots, and platelet-derived growth factors and their receptors in cell differentiation and cell cycle control.

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).

The current volume covers human gene therapy, improving the nutritional value of maize, restriction-modification enzymes, and eight other subjects.

Sixteen contributions cover such topics as the polymerase chain reaction; regulation of alternative splicing; human retinoblastoma susceptibility gene; control of translation initiation in mammalian cells; the utility of streptomycetes as hosts for gene cloning; folding of eukaryotic proteins produc

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.
