Molecular Biology of Weed Control


Book Description

"Weeds are rarely considered a priority despite the fact that all active farmers know that the majority of their variable costs and time are devoted to eradicating them. Even most crop losses due to pests can be traced directly back to weeds, which harbor the pests as secondary hosts. In the Molecular Biology of Weed Control, Jonathan Gressel focuses attention upon the tools of molecular biology that can be used effectively in the science of weed control. Always keeping his perspective congruent with that of the working farmer, Gressel explains how weed biologists and ecologists are beginning to use recently developed tools to control intransigent weed species in modern as well as less developed areas of the world. With his usual candor, Gressel evaluates past efforts, while also exploring future prospects for replacing chemical herbicides with genetic engineering, to improve a crop's ability to compete against its feral cousins for light, nutrients, and water. Like much of Gressel's work, this book should be mandatory reading for all agriculturists and plant scientists, so that they employ and encourage what is truly effective and efficient in meeting one of this century's most critical challenges: maximizing agricultural productivity.




Herbicide Resistance in Weeds and Crops


Book Description

Herbicide Resistance in Weeds and Crops is a collection of papers presented at the 11th Long Ashton International Symposium in September 1989. The said symposium is held to study about the increasing incidence of herbicide-resistant weeds and the consideration of the production of herbicide-resistant crops. The book includes studies that suggest the delay and prevention of herbicide resistance; the gravity of the infestation of different herbicide-resistant weed; the management of herbicide resistance; and the mechanisms of herbicide tolerance. Also covered in the book are the improvement of different herbicides, as well as the prospective development of genetically engineered herbicide-resistant plants. Botanists, biochemists, and farmers would greatly benefit from the text, especially those who would like to explore and study the phenomenon.




Herbicide-Resistant Crops


Book Description

Edited by a recognized leader in the field, Herbicide-Resistant Crops is the first book to cover all of the issues related to the controversial topic of herbicide-resistant crops. It provides extensive discussions of the modern biotechnological methods that have been used to develop such crops, and reviews the implications - both positive and negative - of developing crops that are resistant to herbicides. The creation and anticipated applications of specific herbicide-resistant crops are also discussed. In addition, the book covers the potential impact of herbicide-resistant crops on weed management practices and the environment, and presents issues related to the regulation and economics of these crops. The editor has brought together a diverse group of professionals, representing the several distinct areas impacted by the new technology of herbicide-resistant crops. The wide range of viewpoints presented in this book creates a balanced and complete survey, providing a notable contribution to the literature.




Temporal and Spatial Regulation of Plant Genes


Book Description

First attempts to isolate plant genes were for those genes that are abun dantly expressed in a particular plant organ at a specific stage of devel opment. However, many important gene products are produced in a very minute quantity and in specialized cell types. Such genes can now be isolated using a variety of approaches, some of which are described in this volume. The rapid progress during the last decade in regeneration of a number of crop plants and the availability of molecular tools to introduce foreign genes in plants is allowing the engineering of specific traits of agri cultural importance. These genes must, however, be regulated in a spatial and temporal manner in order to have desired effects on plant devel opment and productivity. The habitat of plants necessitate adaptive responses with respect to the environmental changes. Starting from germination of the seed, the plant begins to sense environmental cues such as moisture, light, temperature and the presence of pathogens, and begins to respond to them. Little is known about various signal transduction pathways that lead to biochemical and morphogenetic responses, in particular, transition from vegetative to reproductive phase. With the availability of tools to generate specific mutations via transposon tagging, identification and isolation of genes affecting these processes may be facilitated. Transfer of these genes into heterologous environments will allow understanding of the complex processes that control plant development.




Weed and Crop Resistance to Herbicides


Book Description

In recent decades, repeated use of herbicides in the same field has imposed selection for resistance in species that were formerly susceptible. On the other hand, considerable research in the private and public sectors has been directed towards introducing herbicide tolerance into susceptible crop species. The evolution of herbicide resistance, understanding its mechanisms, characterisation of resistant weed biotypes, development of herbicide-tolerant crops and management of resistant weeds are described throughout the 36 chapters of this book. It has been written by leading researchers based on the contributions made at the International Symposium on Weed and Crop Resistance to Herbicides held at Córdoba, Spain. This book will be a good reference source for research scientists and advanced students.
