In this volume of Recent Advances in Phytochmistry you will find a record of the pioneering attempts of plant biochemists and molecular biologists to modify the patterns of secondary metabolism in plants, as presented at the 33rd annual meeting of the Phytochemical Society of North America, in Asilomar, California, on June 27 -July I, 1993. The studies described here represent a marriage of the newest of technologies with one of the oldest human activities, exploitation of plant chemistry. They also represent the beginning of a new era of phytochemical research, an era that will undoubtedly begin to provide answers to some of the long-standing questions that have absorbed plant biochemists for the past century. There is, for instance, a common deflating experience to which every worker in the area of plant secondary metabolism can probably relate. After hearing about the latest research findings regarding some aspect of remarkable compound "X", someone in the audience finally directs the inevitable question at the hapless speaker. "Tell me, is anything known as to the biological role of compound "X" in the plant?" The answer, in most cases, must be "essentially nothing"! This is a frustrating scenario for both the speaker and the audience, since the very fact that a complex biosynthetic pathway remains encoded in a plant genome points to an associated selective advantage. The problem is that establishing the nature and scale of that advantage is a very complex task.

The contributions of plant genetics to the production of higher yielding crops of superior quality are well documented. These successes have been realized through the application of plant breeding techniques to a diverse array of genetically controlled traits. Such highly effective breeding procedures will continue to be the primary method employed for the development of new crop cultivars; however, new techniques in cell and molecular biology will provide additional approaches for genetic modification. There has been considerable speculation recently concerning the potential impact of new techniques in cell and molecular biology on plant improvement. These genetic engineering techniques should offer unique opportunities to alter the genetic makeup of crops if applied to existing breeding procedures. Many questions must be answered in order to identify specific applications of these new technologies. This search for applications will require input from plant scientists working on various aspects of crop improvement. This volume is intended to assess the interrelationships between conventional plant breeding and genetic engineering.

Isolated protoplasts are a unique tool for genetic manipulation of plants. Since the discovery of a method for the enzymatic isolation of pro-· toplasts by Professor E. C. Cocking in 1960, tremendous progress has been made in this very fascinating area of research. I have witnessed the struggle in the 1960's and early 1970's, when obtaining a clean prepara tion of protoplasts was considered an achievement. I also shared the pioneering excitement and enthusiasm in this field during the 2nd Inter national Congress of Plant Tissue Culture held at Strasbourg in 1970, where Dr. I. Thkebe of Japan presented his work on the induction of division in tobacco protoplasts. This was followed by my participation in three international conferences devoted to plant protoplasts held in 1972 in Salamanca (Spain) and Versailles (France), and then in 1975 in Nottingham (England). The enthusiasm shown by plant scientists at these meetings was ample proof of the bright future of protoplast technology, and it became evident that protoplasts would playa major role in plant biotechnology, especially in genetic engineering. Since then we have never looked back, and now the methods for isolation, fusion, and culture, as well as regeneration of somatic hybrids, have become routine laboratory procedures for most plant species. Currently the focus is on cereal and tree protoplasts. In order to bring about any genetic manipulation through fusion, in corporation of DNA, and transformation, the regeneration of the entire plant through manipulation of protoplasts is a prerequisite.

During the 45 years of communist regimes in Hungary, Poland and Slovakia, agriculture was centrally directed without regard of quality factors and market needs, and was heavily subsidized. Democratization of the countries and adoption of market driven economies, including agriculture, created conditions that require new thinking and approaches to find market areas that will fill the needs of each country, and provide produce that is not redundant for the Common Market. The aim of this book is to facilitate solving common agricultural problems using the tools of biotechnology. The book addresses five themes: Plant Transformations, Plant Genomics, Breeding Plants for Resistance and Legal Aspects of Biotechnology, including risk assessment. Some specific topics dealt with are: The way from fundamental research to start-up company, Crop improvement by transgenic technology; Strategies for improving resistance; Current procedures for applying risk assessment in genetically modified crops; Questions arising from the implementation of the Hungarian gene technology law; Public perception and legislation of Biotechnology in Poland.

Molecular farming has been hailed as the "third wave" of genetically-modified organisms produced through biotechnology for the bio-based economy of the future. Unlike products of the first wave, such as herbicide resistant crop plants, which were perceived to benefit only the farmers who used them and the agrochemical companies who developed them, products of molecular farming are designed specifically for the benefit of the consumer. Such products could be purified from food or non-food organisms for a range of applications in industry, as well as animal and human health. Alternatively, the products of this technology could be consumed more directly in some edible format, such as milk, eggs, fruits or vegetables. There is a rapidly-growing interest Qn the part of the public as well as in the medical community in the role food plays in health, especially in the immunophysiological impact of food over and above the role of basic nutrition.

Most estimates of the total loss of worldwide agricultural production to pests, pathogens and weeds suggest figures of between 20 and 40 percent. A major goal therefore in current plant biotechnology is the modification of plant genomes to produce crops with enhanced resistance to pests, pathogens and herbicides. This will permit crop protection with reduced levels of application of chemical insecticides and fungicides, and the more selective use of herbicides. This book reviews our current knowledge of this rapidly advancing field and will be of great interest to plant biotechnologists and genetic engineers, as well as workers in plant pathology or agricultural entomology wishing to keep abreast of the subject.

New frontiers of science offer exciting opportunities to stretch rice research horizons. Recent advances in understanding symbiotic Rhizobium-legume interactions at the molecular level, the discovery of endophytic interactions of nitrogen-fixing organisms with non-legumes and the ability to introduce new genes into rice through transformation have created an excellent opportunity to investigate the possibilities for incorporating N2 fixation capability in rice. During a think-tank workshop organized by IRRI in 1992, the participants reaffirmed that such opportunities do exist for cereals and recommended that rice be used as a model system. Subsequently, IRRI developed a New Frontier Project to coordinate the worldwide collaborative efforts among research centers committed to reducing dependency of rice on mineral N resources. An international Rice Biological Nitrogen Fixation (BNF) working group was established to review, share research results/materials, and to catalyze research. This volume contains the deliberations made at the second working group meeting, held 13-15 October, 1996 at the National Institute of Biotechnology and Genetic Engineering (NIBGE) in Faisalabad, Pakistan. The papers presented in the meeting deal with the recent findings on different approaches related to the establishment of endophytic association, development of N2-fixing nodules similar to legumes and transfer of nif genes to rice.

Gene Cloning and Manipulation

Author: Christopher Howe,Howe

Publisher: Cambridge University Press

ISBN: 9780521407007

Category: Medical

Page: 210

View: 4050

Gene cloning and manipulation are the basis for almost all research in molecular biology. This book aims to explain these methods to students by stressing the underlying principles of genetic manipulation in a wide range of organisms. Dr. Howe begins by describing the principles behind cloning DNA in E. coli--the enzymes used, the range of cloning vectors available, and how to screen libraries to find particular clones. The author shows how polymerase chain reaction (PCR) can be used as an alternative approach. He then details how sequences can be exploited, once they have been cloned and identified, by site-directed mutagenesis and over-expression. In the final section, he presents the genetic manipulation of other organisms, including other bacteria, yeast and other fungi, Chlamydomonas, plants, insects (including the use of baculoviruses), and mammals.

While preparing the first edition of this textbook I attended an extension short course on writing agricultural publications. The message I remember was "select your audience and write to it. " There has never been any doubt about the audience for which this textbook was written, the introductory course in crop breeding. In addition, it has become a widely used reference for the graduate plant-breeding student and the practicing plant breeder. In its prepa ration, particular attention has been given to advances in plant-breeding theo ry and their utility in plant-breeding practice. The blend of the theoretical with the practical has set this book apart from other plant-breeding textbooks. The basic structure and the objectives of the earlier editions remain un changed. These objectives are (1) to review essential features of plant re production, Mendelian genetic principles, and related genetic developments applicable in plant-breeding practice; (2) to describe and evaluate established and new plant-breeding procedures and techniques, and (3) to discuss plant breeding objectives with emphasis on the importance of proper choice of objec tive for achieving success in variety development. Because plant-breeding activities are normally organized around specific crops, there are chapters describing breeding procedures and objectives for the major crop plants; the crops were chosen for their economic importance or diversity in breeding sys tems. These chapters provide a broad overview of the kinds of problems with which the breeder must cope.
