Book Description
One of the points clearly stressed in the beginning of this book is that the essential feature of any dynamic system is change and that, where there is change, there may also be growth and evolution. Plant breeding and plant protection have grown and evolved considerably during the past century; they have also witnessed several, important Hegelian changes. This book, by R.A.Robinson, is just such a change in scientific thinking. It is unique in presenting an entirely new insight to plant-parasite relationships, and in providing a practical guide for managing plant pathosystems for man's advantage in agriculture. The author brings together for the first time in a holistic manner the various plant protection and breeding disciplines; he analyses their past limitations and deficiencies and throws useful new light on the nature of parasitism. From this he is able to gain a clear understanding of the functions of the various pathosystem components. On the basis of this understanding he then proposes practical ways for using these components to achieve and maintain the type of balance which is the basis of survival in any evolutionary system, including that of man himself. All this is done in a lively and elegant manner, using logic as the main driving force to elucidate and define entirely new concepts without obstruse mathematical or biochemical formulae.

Book Description
Studies in the Agricultural and Food Sciences: Plant Breeding for Pest and Disease Resistance presents a critical review of the development of resistant varieties of plant to pests and diseases. It discusses the economic impact of pests and diseases; the methods of controlling these pests and diseases; and the challenges being faced by a plant breeder. Some of the topics covered in the book are the general principles and methods of breeding for resistance; importance of parasite variability to the plant breeder; methods of testing for resistance; requirements for successful inoculation; production of resistant varieties; and economic importance of fungal diseases; and variability in fungal pathogen. Pathogenic fungi and fungal diseases are also covered. The control of fungal diseases by resistant varieties is discussed. An in-depth analysis of diseases in plants is provided. The characteristics of bacteria and bacterial diseases are also presented. A chapter is devoted to epidemiology of diseases associated with mycoplasma-like organisms and rickettsia-like organisms. The book can provide useful information to farmers, botanists, students, and researchers.

Book Description
Below-grownd interactions are often seen as the 'dark side' of agroecosystems, especially when more than one crop is grown on the same piece of land at he same time. this book aims to review the amount of light he past decade of research has shed on this topic. It also aims to review ohw far we have come in unravelling the positive and negative aspects of these interactions and how, in dialogue with farmers, we can use the generic principles that are now emerging to look for sita-specifics solutions.

Book Description
Energy and agriculture are both extremely broad subjects and their interactions - the subject of this book - cover almost the full spectrum of the agricultural sciences. Yet the subject is a relatively new one whose importance first received widespread recognition barely a decade ago, following the dramatic increase in oil prices during 1973. The impact of this increase was such as to promote a world-wide debate on the future direction that agriculture should take. This debate was, and is, of particular concern in countries where agriculture plays a leading role in economic and social development. During the last half century many national agricultural systems have been transformed from almost closed, self-sufficient systems with few locally produced inputs geared to satisfy local requirements, to intensive, open systems, utilizing large quantities of energy-rich inputs such as fossil fuel for manufactured agro-chemicals, water distribution and imported animal feedstuffs to produce a range of sophisticated products, often for export, which in tum require many energy-rich inputs for their marketing. This industrialization of agriculture has proved to be very successful in many respects and indeed was accepted as a general model for agricultural development allowing increased productivity and efficiency per unit land, labor and water, even in areas with limited natural resources.

Book Description
The semi-arid zones of the world are fragile ecosystems which are being sub stantially modified by the activities of mankind. Increasing human populations have resulted in greater demands on semi-arid zones for providing human susten ance and the possibility that this may enhance desertification is a grave concern. These zones are harsh habitats for humans. The famines that resulted from drought during the late 1960's and the 1970's in the African Sahel illustrated the unreliability of present agricultural systems in this zone. Large fluctuations in ag ricultural production have occurred in semi-arid zones of Australia, North Ameri ca, and the Soviet Union due to periodic droughts, even though considerable ag ricultural technology has been devoted to agricultural development in these zones. The challenge to mankind is to manage these different semi-arid zones so that pro ductivity is increased and stabilized, and environmental deterioration is decreased. Irrigation can be used to increase and stabilize agricultural production in semi-arid zones as discussed in Volume 5 of this series, Arid Zone Irrigation. The present volume, Agriculture in Semi-Arid Environments, focuses on dryland farming in semi-arid zones, and is relevant to the large areas of the world where rainfall is limiting and where water is not available for irrigation. This volume is designed to assist agricultural development in these areas and consists of reviews and analyses of available information by scientists working in Africa, Australia, and at the U ni versity of California.

Book Description
As befits a volume in the Advanced Series in Agricultural Sciences, this book was written with problems of practical agriculture in mind. One of the ways of controlling plant disease is by using resistant cultivars; and from the wide literature of genetics and biochemistry in plant pathology I have emphasized what seems to bear most closely on breeding for disease resistance. This has a double advantage, for it happens all to the good that this emphasis is also an emphasis on primary causes of disease, as distinct from subsequent processes of symptom expression and other secondary effects. The chapters are entirely modern in outlook. The great revolution in biology this century had its high moments in the elucidation of the DNA double helix in 1953 and the deciphering of the genetic code in 1961. This book, so far as I know, is the first in plant pathology to be conceived within the framework of this new biology. Half the book could not have been written 20 years ago, even if there had then been available all the literature that has since accumulated on the genetics and chemistry of plant disease. The new biology is the cement this book uses to bind the literature together. Another feature of this book is an emphasis on thermodynamics.

Book Description
Since the Russian edition of this book was published in 1975 many new research works have appeared which have made necessary some additions for the English edition, to reflect progress in molecular developmental genetics. Recent important findings in this field have brought about essential corrections to the concept of genetic regulation of the process of cell differentiation. The discovery of the mosaic structure of a gene prompted the re evaluation of our considerations about the regulation of gene activity in eukaryotes, and the data about transcriptional events during ontogenesis are of great importance as well. Formerly it was generally accepted that a derepression of genes was responsible for cell differentiation in the process of develop ment. Recently three important conclusions have been derived (Davidson and Britten, 1979) which help to pose the problem in a new way: 1) Only a small part of single copy sequences of DNA is represented in nuclear RNA of a given type of cell or tissue: 10% to 20% in sea urchin embryos, 11 % in rat liver, 4% to 6% in Drosophila cell culture, etc. Since only about 10% of single copy sequences represent the structural genes (Davidson and Britten, 1973), transcription of almost the whole set of structural genes occurs.
