The Biosaline Concept


Book Description

There are many areas on this world which might lend themselves to agricultural development and which are, at the present, not used for this purpose. Two of the most obvious are desert areas where the salt concentration is very high, both land and water areas. With the development of new approaches and careful research, considerably more productive capability could be developed in these. This volume points out some of the possible approaches as well as results ob tained by a combination of creative research, practical understanding of the problems involved and inventive ways to overcome some of the handicaps of utilizing biosaline areas. This volume grew out of the "International Workshop on Biosaline Research" organized by Mr. Gilbert Devey of the Division of Interna tional programs of the National Science Foundation and directed by Dr. Anthony San Pietro of the Department of Biology of Indiana Uni versity. Since the proceedings of the workshop appeared somewhat limited, it was thought to broaden the spectra of chapters and in clude several topics briefly discussed at the Kiawah workshop.




Biosalinity in Action: Bioproduction with Saline Water


Book Description

Historically, scientists and laymen have regarded salinity as a hazar dous, detrimental phenomenon. This negative view was a principal reason for the lack of agricultural development of most arid and semi arid zones of the world where the major sources of water for biological production are saline. The late Hugo Boyko was probably the first scientist in recent times to challenge this commonly held, pessimistic view of salinity. His research in Israel indicated that many plants can be irrigated with saline water, even at seawater strength, if they are in sandy soil - a technique that could open much barren land to agriculture. This new, even radical, approach to salinity was clearly enunciated in the book he edited and most appropriately entitled 'Salinity and Aridity: New Approaches to Old Problems' (1966). A decade later, three members of the United States National Science Foundation (NSF), Lewis Mayfield, James Aller and Oskar Zaborsky, formulated the 'Biosaline Concept'; namely, that poor soils, high solar insolation and saline water, which prevail in arid lands, should be viewed as useful resources rather than as disadvantages, and that these resources can be used for non-traditional production of food, fuels and chemicals. The First International Workshop on Biosaline Research was con vened at Kiawah Island, South Carolina, in 1977 by A. San Pietro.




Genetic Engineering of Osmoregulation


Book Description

The plant world represents a vast renewable resource for production of food, chemicals and energy. The utilization of this resource is frequently limited by moisture, temperature or salt stress. The emphasis of this volume is on the molecular basis of osmoregulation, adaptation to salt and water stress and applica tions for plant improvement. A unified concept of drought, salt, thermal and other forms of stress is proposed and discussed in the publication. The volume developed from a symposium entitled "Genetic Engi neering of Osmoregulation: Impact on Plant Productivity for Food, Chemicals and Energy," organized by D. W. Rains and R. C. Valentine in cooperation with Brookhaven National Laboratory and directed by D. W. Rains and A. Hollaender. The program was supported by a grant from the National Science Founda~ion, Division of Problem Focused Research, Problem Analysis Group, and the Department of Energy. This symposium is one of several in the past and pending which deal with potential applications of genetic engineering in agri culture. Since the question was raised several times during the meeting it is perhaps a convenient time to attempt to define gene tic engineering in the context of the meeting. • Genetic engineering of osmoregulation is simply the application of the science of genetics toward osmo tically tolerant microbes and plants. • Recombinant DNA is regarded as just another tool along with conventional genetics to be utilized for improvement of microbes and plants.

Prospects for Saline Agriculture


Book Description

Saline land is a resource capable of significant production. Recent advances in research in breeding for salt tolerance in wheat, biotechnology in rice, and selection and rehabilitation of salt-tolerant plants are of economic importance in arid/saline conditions. This book gives some practical approaches for saline agriculture and afforestation, and describes examples of cultivating salt-tolerant/halophytic plants for commercial interest on salt-affected land or with highly salinized water in Australia, China, Central Asia, Egypt, Pakistan, and Russia. It also explores the possibilities of arid/saline agriculture and afforestation in UAE.




Genetic Engineering of Plants


Book Description

William C. Taylor Department of Genetics University of California Berkeley, California 94720 It is evident by now that there is a great deal of interest in exploiting the new technologies to genetically engineer new forms of plants. A purpose of this meeting is to assess the possibilities. The papers that follow are concerned with the analysis of single genes or small gene families. We will read about genes found within the nucleus, plastids, and bacteria which are responsible for agri culturally important traits. Given that these genes can be isolated by recombinant DNA techniques, there are two possible strategies for plant engineering. One involves isolating a gene from a cultivated plant, changing it in a specific way and then inserting it back into the same plant where it produces an altered gene product. An example might be changing the amino acid composition of a seed pro tein so as to make the seed a more efficient food source. A second strategy is to isolate a gene from one species and transfer it to another species where it produces a desirable feature. An example might be the transfer of a gene which encodes a more efficient pho tosynthetic enzyme from a wild relative into a cultivated species. There are three technical hurdles which must be overcome for either strategy to work. The gene of interest must be physically isolated.







Water Resources and Agricultural Development in the Tropics


Book Description

First published in 1988. There are many excellent texts on water supply and irrigation engineering, irrigation economics, agricultural development and the problems which often plague such efforts. Few syntheses of such writings have been made, despite a clear need for them from people interested in water resources and agricultural development: students of geography, economics, development studies and agricultural management, administrators, planners and aid agency staff. This book attempts to provide a broad interdisciplinary introduction for such people.
