Preface
New advances in plant sciences particularly related to abiotic stresses are frequently appearing in the literature. It is imperative to keep updated ourselves with advances in plant abiotic stresses such as salinity and water stress to meet the current scientific challenges, particularly to meeting the growing food demand for world population. New technologies are trying to find out ways through which we can better understand how plants respond to environment and how to improve abiotic stress tolerance in crop plants and what effective strategies should be undertaken to overcome/mitigate the adverse effects of different abiotic stresses. This book is presenting a timely and wide-ranging overview of the salinity and water stresses. In the three sections of this book, advanced knowledge about molecular, biochemical and physiological basis of plant salt and water stress tolerance is presented covering a broad range of topics in this connection: • Nature of environmental adversaries that affect plant productivity from the viewpoint of three interrelated disciplines; eco-physiology, breeding, and socio-economics • Potential biochemical and physiological indicators for successful breeding • Molecular biological approaches to identify key genes responsible for traits involved in salt and water stress tolerance • Alternative shotgun approaches to induce stress tolerance • Alternative non-traditional plants that may be grown on stress hit areas and • Economic utilization of salt affected areas by growing halophytes In addition, the strategies economically viable for introducing economically important crops in non-agricultural land are discussed, and this
