Plants depend on physiological mechanisms to combat adverse environmental conditions, such as pathogen attack, wounding, drought, cold, freezing, salt, UV, intense light, heavy metals and SO2. Many of these cause excess production of active oxygen species in plant cells. Plants have evolved complex defense systems against such oxidative stress. The study of these mechanisms has become a fast-moving, important field to many biologists. Written and edited by world-leading scientists, Oxidative Stress in Plants explores the current knowledge of the mechanisms by which various biotic and abiotic environmental stress conditions produce oxygen radicals. The text considers the biochemistry and molecular biology of both non-enzymatic (vitamin C, glutathione) and enzymatic systems which eliminate active oxygen species. In addition, the book discusses evidence that active oxygen species and antioxidants act as signals which trigger defense reactions.

Plants depend for their survival on physiological mechanisms with which to combat adverse environmental conditions, such as pathogen attack, wounding, drought, cold, freezig, salt, UV, intense light, hevy metals, and SO2. Many of these cause excess production of active oxygen species in plant cells. Plants in turn have evolved complex defence systems against such oxidative stress. The study of these mechanisms has become a fast-moving, topical firld of importance to many biologists studying the effect of the environment on living organisms.
Written and edited by world-leading scientists, Oxidative Stress in Plants reviews the current knowledge of the mechanisms by which various biotic and abiotic environmental stress conditions produce oxygen eadicals. The biochemistry and molecular biology of both non-enzymatic (Vitamin C; Glutathione) and enzymatic systems which eliminate active oxygen species are considered in detail. In addition, the book discusses evidence that active oxygen species and antioxidants act as signals which trigger defence reactions.

Over the past fifty years plant breeders have achieved impressive improvements in yield, quality and disease resistance. These gains suggest that many more modifications might be introduced if appropriate genes can be identified. Current DNA techniques allow the construction of transgenic plants and this important new book reviews the current state of knowledge. A team of leading researchers provide in-depth reviews at the cutting edge of technology for laboratory techniques for the transformation of important soil microorganisms and recalcitrant plants of economic value. The book is divided into three sections: soil microorganisms; cereal crops; and industrially important plants. The most effective methods used to date are compared, and their merits and limitations discussed. Some chapters emphasise case studies and applications. In cases where obstacles remain to be overcome, an overview of progress to date is given. The book will serve as a general guide and reference tool for those working on transformation in microbiology and plant science.
